第十一：Go to Physical tab and in the Material drop down menu choose Steel Mild. We will need those properties for our FEA test. Once you are finished save your part.

Step 15: In the Assemble tab choose place component. In the new window browse to the location we saved our first part, select it and place it. By deafault the first part that is placed in an assembly or weldment file is grounded. You can change that later but for this tutorial we will keep this configuration.

Step 19: Then choose flush instead of mate (red circle) and select the two faces shown. In the Offset value (red circle) put 40mm offset. Click Apply.

Step 21: This is what we should be looking at. Now Part 2 is fully constraint.


Step 22: Next we place our third part 2 times. Use the exact same steps for placing part 2.
