Automatic loop generation completely automates the loop generation process for loops. This is especially helpful for the AutoCATS user. Usually it is difficult to know which path a loop should follow. Once Autoloop has been selected, the program shells out of the AutoCATS Modeler to run a program which generates an optimum vector loop. The user is then prompted for controlled dimension tolerances for both lengths and angles. Tolerances may be either typed in or selected from a pop-up tolerance menu. The pop-up tolerance menu is the same as for the GAP, LEN, and DEP specifications.
Command: AutoloopGenerating Loops. . .Is this loop correct?/N: (Enter "Y" or "N" appropriately)Determining dependencies. . .Enter symmetrical tolerance on indicated dimension, <+/- 0.02500>
Nominal length: ##.## ±(Enter symmetrical tolerance)
Tolerances may be inputted either symmetrically, non-symmetrically, or by max/min limits. To change from symmetrical tolerances to non-symmetrical tolerances, select the appropriate symbol on the default SymTols pop-up menu. If the controlled dimension is an angle, the prompt will be as follows:
Enter symmetrical tolerance on indicated dimension, <+/- 0.0000>
Nominal angle (in degrees): ##.# ± (Enter angle tolerance in degrees)
Once all control dimensions have been toleranced, the program prompts for the location of the loop name and then continues with the next loop until all loops have been generated.
Select location to display loop name:Creating Loop...Generating Loops...
Edit Tolerance
After loops are created the vector tolerances may be edited.
Command: EDIT_TOLSelect vector to modify: (Select the vector you want to modify)
AutoCATS does not allow the user to change the tolerance if the vector is a dependent variable.
Enter symmetrical tolerance on indicated dimension, <+/- 0.0000>
Nominal angle (in degrees): ##.# ± (Enter angle tolerance in degrees)
Modify another vector/N?
Delete Loop
After loops are created they may be deleted by selecting this side menu option. Remember to use this command to delete all of the information related to the loop.
Command: DELETE_LSelect loop name to delete:Delete another loop/N?
Command: AutoloopGenerating Loops. . .Is this loop correct?
Nominal length: ##.## ±(Enter symmetrical tolerance)
