P 4

Import contour fi le under [File] > [Import]

Navigate to the folder you saved the contour lines in and Open.

2. IMPORT .DWG or .DXF

P 5

Your contours will be imported as polylines.Make sure that:

The contours are located around the centre of the workspace.If not, type in “[Move]” to move the contours to the centre. The centre is marked with a dark grey grid.(This is to prevent display/meshing inaccuracy)

3. POSITION

P 6

If not already done, trim the contour to your site boundary.

1. Draw an outline (using “Polyline” or “Rectangle” tool)2. Use the outline to trim the contours (type “[Trim]”)

4. FORM BOUNDARY

Page 8: Guide: Contour Modelling Software: Rhinoceros · Open Rhino, under Start> All Programs> Rhinoceros 5> Rhinoceros 5.0 1. OPEN RHINO. P 4 Import contour fi le under [File] > [Import]

P 7

Select contour lines and type command “[Patch]”

5. PATCH

P 8

Change settings in the surface UV span directions to determine the amount of detail

Smaller number of UV (10 x 10) = less detailLarger numebr of UV (200 x 200) = more detail

Note: A large number of UV will take a longer time to generate

6. PATCH SURFACE OPTIONS

P 10

Patch will create a surface that might extend outside of the boundary, to trim unwanted extensions,

Trim with boundary:

1. Select boundary2. Create trim box: type command “Extrudecrv”3. Type command “Trim”4. Trim unwanted part of surface5. Hide or delete trim box

7. TRIM

You have now completed a terrain model.
