Solving Problems with Solidworks:

1.) [ ] If your assembly has pins that should be located in specific locations.....Place them using the move component tool and FIX them in place

     [ ] Concentric Mate your links to the fixed pins

     [ ] Face mate the end of the pins to the side of the links

2.) [ ] If your assembly has objects that must be located in specific locations.....Place them using the move component tool and FIX them in place.

Measure Tool: The Measure Tool is used to get the distance between points, the angle between lines, the displacement of parts in an assembly, and anything else

you would use a ruler or protractor for in real life. To open the Measure Tool you can select it from: Tools->Measure...

Or you can select the measure tool using the Tools Button on the main toolbar:

Using the tool is very simple. You can select points or lines and it gives you information regarding the two selected entities. Pay particular attention to delta x, y, and z values. It allows you to determine distance between points independently

from the global origin:

To measure the angle between 2 parts you must select 2 intersecting lines or edges on those parts. Look at the following picture for clarification(the 2 red edges

were selected):

To change the units for display, click the Options... button and use the drop down menu to select the units you want:

Move Component: It is often important to be able to move a part in an assembly by a specified displacement or angle or to a specific xyz coordinate. The move

component tool can be used for this if you understand how to properly use the tool. It is located on the main toolbar:

The Move Component tool has the following options (they are explained in detail below):

1.) Free Drag option is the default and it allows you to drag the selected part wherever you want. It is useful for positioning parts for mates or for moving

assemblies. It is not useful for accurate movement.

2.) Along Assembly XYZ is an inaccurate method of moving a part in exclusively the x y or z direction.

3.)Move to XYZ position: This is useful if you want to move a point on a part to a specific xyz coordinate. Consider the following link, which is located somewhere

random in space.

    To move the link to the origin, first select a point on the link. (Notice that the origin is below the selected point and to the right at the location 0,0,0)

    Next click the Move Component button on the assembly toolbar and select 'To XYZ Position.'

Enter (0,0,0) as the coordinates and hit apply:

     Now the the point on the link is at the origin of the assembly:

4.) Move by delta XYZ: This is useful when you want to move a part a specific distance relative to its current location. You can choose to move by any

combination of x, y and z distances as long as the part is not fixed or restrained by a mate. In this example, move a pin in a slot by 10mm to the right. Note that since the pin is mated to the inside of the slot you cannot move it in the y or z directions.

    The first step is to select a point on the pin, or the pin itself:

    Next click the Move Component button on the assembly toolbar and select 'By delta XYZ.'

    Change the value in deltaX to 10mm and hit apply:

    Now the pin has moved 10mm to the right:

Rotate Component: It is often important to be able to rotate a component in an assembly by a specific angle about the x y or z axis. The rotate component tool can

be used for this if you understand how to properly use the tool. It is located on the main toolbar:

In this example the green link will be rotated around the pin by 45 degrees in the positive z direction. To do this, click the Rotate Component button. In the window

that appears to the left of the assembly, use the drop down list to select 'By Delta XYZ'

Enter 45 into the Z text box and click apply:

The link will rotate 45 degrees and stop:

Changing Units:

Select 'Tools' -> 'Options.' On the 'Document Properties' window select 'Units' and change them to whatever you want:

Exporting to ANSYS: ANSYS uses a different file format from SolidWorks but it can still read SolidWorks parts as long as you first convert them to the IGES[Initial

Graphics Exchange Specification] format.

1.) After saving the file in SolidWorks as the usual .sldprt  file, and while that file is still open in SolidWorks, select 'File' -> 'Save As...' and change 'Save as Type' to

'IGES File (*.igs)':

2.) Click Options in the 'Save As' window and change 'Surface Representation' to 'ANSYS':

3.) click 'OK' and then 'Save'

Printing: To print what you see on the screen you have to change a setting in page setup. 'File' -> 'Page Setup'.

Otherwise the printout will be the actual size of the part you are working with. In some cases this is larger than a piece of paper.

PLANAR JOINTS:

NOTE: if you are not familiar with the layout of SolidWorks, then click here to familiarize yourself with the layout. If you are unfamiliar with assemblies please see the assembly

tutorial.

There are three types of Planar Joints: Pin Joint, Pin-in-Slot, and Sliding. Solidworks will allow us to study these joints in a way that a simple drawing or

schematic would not allow. We will be able to actively move the joints and see the limitations of each joint type.

This tutorial uses files in the parts.zip package. Make sure you download and extract the files to your computer. The assemblies in this tutorial come from the "planar

joints" directory. RED pins represent pins that are fixed from translating...each still allows rotation of the body connected to it.

The first Planar Joint is called a Pin Joint. It is one you are already familiar with since it can be seen in most mechanical systems.

It only permits two bodies to pivot relative to another.

As an example of a pin joint consider a scissors lift shown below. This mechanism, which serves to raise platform holding workers, has a series of links which are

unfolded by several hydraulic cylinders.  Each pair of links is connected by a pin joint which enables them to pivot with respect to each other:

To examine a simple pin joint in solidworks, follow these steps:

1.) Goto File->Open and select "pinjoint.SLDASM" from the planar joints folder

2.) using the rotate component button and the move component button see how the pin joint moves in space. Notice the limitations of this joint:

You can see that there are actually two pin joints in this assembly.  The pin in a pin-joint could be fixed in position, or it can join two parts, both of which can move.

The second Planar Joint is called a Pin-in-Slot joint. A pin-in-slot joint allows the joined bodies to pivot with respect to each other and to translate with respect to

each other in one direction.  However translation in the perpendicular direction is restricted.

As an example of a pin-in-slot joint, consider the motorized door opener shown.  The end of one member has a pin with a roller, which rolls in a slot in the door:

To examine a simple pin-in-slot joint in solidworks, follow these steps:

1.) Goto File->Open and select "pininslot.SLDASM" from the planar joints folder

2.) using the rotate component button and the move component button see how the pin-in-slot joint moves in space. Notice the limitations of this joint:

You can see that the link with a slot and a hole is pinned at its hole to some fixed body which is not shown, but that a second link is connected to the slot with a pin.

The pin-in-slot joint is that connecting the two links.

ALSO: Notice that you can only translate the link with two holes, not rotate it. This is a limitation of Solidworks. A work around to this problem

is to "fix" the link in space by right clicking on link3slide in the Feature Manager Design Tree and click "Fix":

You may get a message that the assembly cannot be solved with this mate.  However, you will find that it probably works.  Now the link with two holes can be

both translated and rotated. You can return to the initial state in which the slotted link floats by right clicking on link3slide in the Feature Manager Design Tree and

selecting "Float":

The third Planar Joint is called a sliding joint. A sliding joint prevents two bodies from rotating with respect to one other and permits the bodies to translate with

respect to one another only in a single direction.

As an example of a sliding joint, consider the mechanism for adjusting the position of the back to the exercise machine.  The black sleeve can only slide on the white

member.  Notice that the sleeve is locked into position by the spring loaded pin (with the black handle) which engages one of the holes in the white member.  But

when this pin is retracted, the sleeve can slide.  Notice that another link is pinned to the sleeve:

To examine a simple pin-in-slot joint in solidworks, follow these steps:

1.) Goto File->Open and select "slidingjoint.SLDASM" from the planar joints folder

2.) using the move component button see how the sliding joint moves in space. Notice the limitations of this joint:

You can see that a link with a slot and a hole is pinned at its hole to some fixed body which is not shown.  A second member with a square peg engages the slot. 

While the link with the slot can pivot about its pin joint, the second member can only slide in one direction relative to the slotted link. The sliding joint is that

connecting the two links.
