Assemble Exploded ModelAssemble Exploded Model

This tutorial shows how you can build a model in an exploded or unassembled form and automatically have it assemble before simulation. This can be useful if your

model is complicated and has many small and closely connected parts.

4

What You Should AccomplishWhat You Should Accomplish

When you complete this tutorial you will have an exploded model that assembles

and then runs a simulation.

• Make sure the units are correctly set.

• Make sure the joints is in the correct direction.

• Check dimensions of your parts to make sure they are correct.

• Check orientation of the parts and joints to make sure it is correct.

• Make sure your model verification is successful

• Make sure the measures are set properly.

• Make sure the plot is displaying the correct set of results.
