Redefining Imported Attributes

About Redefining Imported Attributes

When you import geometry, you can revise imported attributes to determine whether

an imported feature should be a solid or whether adjacent surfaces should be joined.

To Redefine Imported Attributes

1. Select the feature in the Model Tree and right-click.

2. Click Edit Definition on the shortcut menu.

Alternatively, select the feature and click Edit > Definition.

3. Click Edit > Feature Properties. The Properties menu appears.

4. Select one the following:

o Make Solid—Generates a solid feature from the imported data. When not

selected, a surface feature is generated.

o Join Surfs—Joins surfaces that share the same boundary whenever

possible.

o Join Layers—Joins layers of all selected surfaces.

Note: Make Solid and Join Surfs work in combination. That is, when you select

Make Solid, Join Surfs is automatically selected and a closed volume with

material is created. Conversely, if you do not select Join Surfs, Make Solid is

also not selected. If the imported geometry has been converted into a solid

protrusion, both Make Solid and Join Surfs are selected.

To Delete Selected Entities of an Imported Surface

1. Select a feature in the Model Tree and right-click.


Alternatively, click Edit > Definition.

3. Click Edit > Delete. The DELETE ENT menu appears.

4. Clear the selections for the types of entities that you do not want to select. The

entity types are:

o Point—Selects points for deletion (selected by default).

o Datum Plane—Selects datum planes for deletion (selected by default).

o Curve—Selects curves for deletion (selected by default).

o Surface—Selects surfaces for deletion.

Import DataDoctor - Help Topic Collection

2

5. Click Select Item on the DELETE ENT menu. Use the SELECT menu to select

the items to delete.

6. Click Done Sel or specify other entity types again.

7. To continue selecting entities, use the DELETE ENT menu and click Select Item

again. The SELECT menu reappears so you can add items to your selection.

Rehighlight in the SELECT menu highlights the cumulative results of all

selections.

8. Click Done on the DELETE ENT menu.

To Join Surfaces in an Imported Feature




3. Click Edit > Feature Properties. The Properties menu appears. Make Solid

and Join Surfs are both selected. To select only Join Surfs, clear the selection

and select it again.

Note: When you clear Join Surfs, Make Solid is also not selected.

4. Click Join Surfs.

5. Click Done/Return. Surfaces that share the same boundary are joined.

6. Use Fix Bndries to repair geometry and join additional surface boundaries. After

all surfaces are joined and all quilts have created closed volumes, you can fill

these volumes with material by clearing Join Surfs.

To Exclude Surfaces from a Quilt



Alternatively, click Edit > Definition and select the feature.

3. Click Edit > Feature Properties. The Properties menu appears.

4. Click Exclude Surfs. Boundaries of the surfaces that are in the set are

highlighted in blue. The EXCLUDE SRFS menu appears.

5. Select one of the following:

o Add—Adds surfaces to the set of surfaces to be excluded.

o Remove—Removes surfaces from the set of surfaces to be excluded.

o Remove All—Removes all surfaces from the excluded set of surfaces.

6. Click Done. The imported feature regenerates if Join Surfs is selected. All

boundaries of the excluded surfaces are displayed in yellow.

DataDoctor

3

Excluding Surfaces

Use Exclude Surfs in the Properties menu to separate some of the imported

surfaces after they have been joined using Join Surfs, or specify surfaces to which

Join Surfs should not be applied.

Use Exclude Surfs to select surfaces to be excluded from a topology. You can add

or remove surfaces from the excluded set.

Some surfaces may appear joined with the quilt even after exclusion. These surfaces

can be excluded only in groups because they were joined as a quilt during import.

The original surface is broken down into multiple surface patches because of

discontinuities in surface curvature or tangency, or both. These surface patches are

not individual surfaces. You cannot completely exclude them from the quilt using

Exclude Surfs.

To Close Gaps and Fix Tangency

After surfaces have been joined automatically using Join Surfs, some gaps may still

be present. They are displayed in a model as one-sided surface edges (edges that

are not shared by another surface) in yellow. Use Fix Bndries in the MANUAL

REPAIR menu to repair them manually. You can also improve tangency conditions.

The fix boundaries procedure is nonparametric and therefore not reversible. To undo

your changes, import the file again.




3. Click Geometry > Heal Geometry > Manual. The FIX OPTIONS menu

appears.

4. Click Zip Gaps or Fix Tangency.

5. Select edges using the SEL CHAINS menu.

6. To set the criterion value, use the MAX VALUE menu.

7. After you have selected the first chain of edges, click Done Sel on the SELECT

menu.

8. Click Done on the EDGE SEL menu. The selected edges are highlighted in blue.

9. Select the second set of edges.

After you have selected both sets, a maximum gap size and a range of dihedral

angles measured between relevant surfaces in the message window are printed.

10. Click Unsel Chain to clear the selection of edges.

11. Use the EDGE SEL menu to indicate edges that you do not want selected.

12. Select all edges and use the SEL CHAINS menu.


4

13. Select Zip Gaps to close gaps, or FixTangency to fix tangency. Surfaces for the

selected edges are repaired. As the quilt is processed, a red mesh displays the

repaired surfaces. After processing is complete, you can verify the results of the

complete procedure. Edges that are not repaired remain blue.

14. To accept or reject the current state of the model, click Accept or Reject,

respectively, on the ACCEPT FIX menu. If you click Accept, you cannot undo

these changes.

15. If gaps remain in the imported surfaces, return to Step 3, increase the criterion

value, and continue through Step 7.

To Fix Boundaries with Problem Surfaces




appears.


o Zip Gaps—Closes gaps between surfaces so that they can then be joined

using Join Surfs.

o Fix Tangency—Makes surfaces tangent along selected edges. You can

apply tangency only to small (less than 10 degrees) dihedral angles.

Boundaries that have gaps are not automatically selected. Use Fix

Tangency on a quilt that is completely zipped and has fixed vertices.

o FixQuiltBndry—Converts a multi-segment quilt boundary to a single edge.

Only almost tangential segments are considered for a possible merge.

o Edit Bndry—Enables you to manually alter the trimming boundary of a

surface.

o FixVertices—Moves vertices in a set for better alignment.

Fixing Boundaries with Configuration Options

Imported geometry can contain inconsistencies in topology, incorrect alignments, or

discontinuities in geometric entities. When you import surfaces to Pro/ENGINEER,

some of the surface boundaries may require repair. Pro/ENGINEER provides a set of

tools to repair these problems.

You can instruct the system to repair some problem boundaries in the imported

surfaces during the import process by setting the following configuration options:

• fix_boundaries_on_import

• intf3d_in_close_open_boundaries

For more information, see the Pro/ENGINEER Interface Help module.

DataDoctor

SEL CHAINS Menu

Auto Select automatically selects all problem boundaries based on the value of

MaxGapDist or MaxDihedral.

While selecting, you are informed of the progress and displays a Stop sign. Use the

Stop sign to interrupt the selection process at any time. After the selection is

complete, the selected edges are highlighted in blue. You can then add more edges

manually using Sel Chain, Single, or Chain.

If you are not satisfied with the results of the automatic search, you can reset the

selection criteria and use Auto Select again. By increasing the maximum value of

the selection range, you can cause larger gaps (when closing gaps) or larger dihedral

angles (when fixing tangency) to be included in the selection.

MAX VALUE Menu

Default—Uses the default value.

Enter—Enables you to type a maximum value of gaps between boundary edges and

vertices if zipping gaps, or maximum dihedral angle if fixing tangency. If you know

the accuracy at which the part was created, it can serve as an initial value for setting

the maximum gap criterion. For MaxGapDist and MaxDihedral, type values in

model length units and model angular units, respectively.

The best practice is to accept the fixed geometry for all boundaries at a given value,

increase the value if there are any selected edges that could not be fixed or any

problem edges that were not selected, and use Auto Select again. The gap and

dihedral setting for a particular boundary remain with the fixed tangency and gaps.

Start with the default value.

When using MaxGapDist, use the accuracy level of another system as the gap is

probably smaller than the current one. The largest gap in the selected edges that

could not be fixed is measured and a slightly larger value is suggested to you.

Sel Chain—Enables you to manually select edges on both sides of the gap to be

fixed. For each side, indicate the desired selection technique using the EDGE SEL

menu.

Single—Selects individual edges forming a chain on each side of the gap.

Chain—Selects a chain of edges on each side of the gap by picking an edge from this

chain.

To Fix the Quilt Boundaries

You can find quilt boundaries (chains of one-sided edges, colored yellow) composed

of multiple segments that are almost tangential and nearly an isoline, and replace

each one with one edge.

Modify—Displays the MODIFY menu. Changes a selected chain of edges.

Delete—Removes an edge from a chain. Identify the chain by selecting its two ends

or select the orange edge.

You must replace a single open chain with a single open chain or a single closed loop

with a single closed loop before you exit the EDIT BNDRY menu. Otherwise, the

current edit boundary procedure is aborted.

Combine—Selects two chains of edges to combine into one.

Undo Last—Reverts to the state before the last procedure from the EDIT BNDRY

menu if the procedure was Create, Modify, Delete, or Combine.

Preview—Shows the results of the changes before executing them.

Geom Check—Obtains information about problem areas.

Set Domain—Allows you to mesh the domain of the surface and to expand the

domain.

Creating a Chain of Edges

If you click Create on the EDIT BNDRY menu, the CREATE menu appears with the

following:

• Project—Creates an edge by projecting a curve or a chain of edges onto the

surface.

• Make Isoline—Creates an edge by creating an isoline through a reference point.

If you click Make Isoline, a red arrow appears at the reference point, pointing

along one possible isoline direction. The CHOOSE menu appears with the

following:

o Accept—Accepts the displayed direction for creating the isoline.

o Next—Flips the red arrow to the alternative isoline direction, more or less

normal to the previously displayed one and along the surface.

o Connect—Creates an edge by connecting two or more points.

o Intersect—Creates an edge where the selected surface intersects with another

surface.

Modifying an Existing Chain of Edges

If you click Modify on the EDIT BNDRY menu, the MODIFY EDGS menu appears

with the following:

• Straighten—Replaces a subchain by a simple two-point edge.

• Merge Edges—Merges the subchain into one continuous edge. Select an edge

for the whole chain or select two vertices to define the range for the chain.


8

• Move Vertex—Places a vertex of the chain at a new reference point. The edges

at the vertex are straightened and any existing tangency conditions at that

vertex are removed.

• SetTanCond—Sets or changes tangency conditions for the edge. The start and

endpoints of the edge are marked by corresponding arrows. The TAN CONDS

menu appears with the following:

o Start—Defines the tangency at the start of the edge.

o End—Defines the tangency at the end of the edge.

o Tangent—Makes the edge tangent to a reference at the selected end. If

there are several possible references to which the edge could be tangent,

one of them is highlighted in red and the CHOOSE menu appears. Use

Next and Previous to cycle through the possible references and click

Accept. Click Flip or Okay on the DIRECTION menu to position the red

arrow to specify the direction of tangency.

o Normal—Makes the edge normal to a reference at the selected end. The

procedure for choosing the reference and the direction of normalcy is

similar to that described earlier for Tangent.

o Free—Removes the requirement for the edge to be tangent or normal to a

reference at the selected end.

• Divide—Divides the edge into two at a selected point. No tangency conditions

exist between the two new subchains at the selected point.

To Fix the Quilt Vertices

You can find quilt boundaries (chains of one-sided edges, colored yellow) composed

of multiple segments that are almost tangential and nearly an isoline. Replace each

one with one edge.

Cleaning Up the Imported Geometry

About Cleaning Up the Imported Geometry

Before you import a geometry file, ensure the accuracy of data transfer by:

• Setting the appropriate configuration options.

• Choosing the appropriate absolute accuracy to ensure a successful data transfer.

Absolute accuracy is based on the part size and the smallest edge in the imported

feature that needs to be preserved.

After you import the geometry

• Clean up the surface either automatically or manually.

• If necessary, create Pro/ENGINEER parametric geometry to fill gaps or holes and

collapse the geometry into the imported feature.

Automatic or Manual Cleanup

Automatic surface cleanup repairs the imported quilt by rebuilding the wireframe

surfaces with minimal user interaction. The result is geometry with precision and

integrity, but there can be changes in the parametrics of the imported surface. If you

must preserve the parametrics of an imported surface, select Zip Gaps or Edit

Boundary from Manual.

Collapsing Geometry

After automatic or manual surface cleanup, you may still have an imported quilt with

a missing surface patch or geometry that cannot be repaired. After deleting the

distorted patches and recreating the missing geometry, use Collapse Geometry to

add the parametric geometry to the imported feature.

Selecting Features for Collapsing Geometry

Features such as quilts, curves, datum curves, datum planes, datum points, and

datum axes can be collapsed into the target import feature. Solids, grouped or

patterned features or both, and features created prior to the target feature cannot be

selected for collapse. After the selected features are collapsed, they are deleted from

the feature list and the Model Tree. If a selected feature has child features, you can

include the dependent features in the target feature or deal with them later.

To Manually Redefine Imported Features

Note: Save the object frequently. If there are surfaces you cannot fix, place them on

a layer and then blank the layer.

Suggested Tools and Strategies for Cleaning Up Imported Geometry

The following techniques may be useful when you are working with a small

percentage of data containing geometry that cannot be repaired.

• Use the analysis tools provided to investigate any problem geometry:

o To highlight problems with surface parameterization, mesh surfaces. If the

U and V mesh lines are almost parallel on the surface, a near singularity is

created, that is, incorrect parameterization.

o To obtain information on appropriate settings for the MaxGapDist value,

measure the distance between surface edges or vertices.

• If Geom Check information is not available for a particular problem, isolate the

problem area by manually fixing edges one at a time. With remaining problem

edges, use the preceding techniques.

• If you have surfaces that overlap in a portion of their area, but need to keep both

in the model, use Edit Boundary to create a common edge.

• If you cannot repair a boundary or vertex using Fix Bndries, remove one of the

surfaces along the edge, and create replacement surfaces using Pro/ENGINEER

features. Merge the new surface with the imported geometry. Identify the surface

to remove by investigating the edges along the problem boundary using analysis

tools. You may want to remove surfaces that have the worst discontinuities along

the edge or are easiest to recreate.

• If you cannot import a particular surface, recreate the missing surface based on

boundary edges from adjacent surfaces as discussed above.

• Surface and Merge merge individual quilts, but you cannot merge internal

edges of a quilt. That is, you cannot merge a surface quilt with itself. However,

yellow edges that remain in the model even after Join Surfs has been used are

probably internal to the quilt, and cannot be merged using Surface and Merge.

Guidelines for Manual Surface Cleanup

If the result of your automatic cleanup is not satisfactory, follow these guidelines to

perform a manual cleanup:

• View all diagnostic information.

• Address overlapping geometry and coincident surfaces.

• Exclude surfaces as necessary.

• Save frequently. Changes are not parametric.


12

Combination of Data Types

There are several common combinations of imported data. A file can contain 2D and

3D information, in drawing and model space. You can read these files into

Pro/ENGINEER either as drawings or as parts or assemblies, or both.

Another typical combination is that of wireframe and surface data in one part. The

basic part is usually created with wireframe entities, and surfaces are created only

where there are rounds or other interesting geometry. The strategies already

explained for working with wireframe and surface data can be applied to the

combinations of imported data as well.

Tip: Working with Edit Boundary Functionality

When editing boundaries,

• Save the part often because you cannot undo changes after you exit the EDIT

BNDRY menu.

• You cannot create or modify edges to be off the surface. All new edges that are

created and old edges that are modified are always projected on to the surface. If

necessary, exclude the incorrect imported surfaces and blank them on a layer.

Recreate new surfaces and merge them into the imported quilt.

• Use Query Select to pick the appropriate entities. For example, when moving or

creating vertices, use Query Select to pick the ends of edges. You can then

connect ends of new and existing edges.

• When possible, use Modify on the EDIT BNDRY menu to change the existing

edges rather than create new edges. It is easier to maintain closed loops and

vertex alignment when you adjust existing boundaries, for example, by moving

vertices.

• In many cases, it is more important to align vertices than to align the edges

between them.

• Domain meshes can be helpful in viewing surfaces that need to be edited.
