DOFcheck

This menu item allows you check the degrees of freedom (DOF) for each part individually or all of the parts at once.
Command: DOFcheckSelect DRF on part to check DOF: (Select part's DRF)
The following prompts will then appear as AutoCATS performs the analysis.
Performing DOF analysis on part PART_1 . . .
If for example PART_1 has the correct number of joints and is constrained the next prompts will appear as follows:
PART_1 constrained and has 0 translational DOF left.PART_1 constrained and has 0 rotational DOF left.Remove all DOF arrows? Y/: (Enter Y, yes, or N, No appropriately)
On the other hand, if PART_1 does not have the correct number of joints (for example, one joint instead of two) then the prompt will appear as below:
Select location to display translational DOF directions:PART_1 is unconstrained in indicated direction and as 1 translational DOF left.Additional joints may be required for accurate tolerance analysis.
After selecting a display location in a readable area an arrow will be inserted with will show the remaining unconstrained DOF direction. AutoCATS will then display the rotational DOF.
Select location to display rotational DOF directions:PART_1 unconstrained about indicated axis and has 1 rotational DOF left.Additional joints may be required for accurate tolerance analysis.Press any key to continue.Remove all DOF arrows? Y/:
Once you have viewed the DOF constraints, the arrows may be either removed, or kept in place for future reference
