Examine Constraints
Following a Complete command, you should always check the part to make sure that a reasonable set of constraints has been assigned. Check the following:
1. Are all important dimensions constrained?
Click the Show radio button in Generate Constraints, select Used from the Act On list and Dimensions from the Type list, then click Apply.Notice that the dimension for the top of the plate has not been constrained. This is not needed in this case because other constraints fix this line.
2. Are there any Distance or Size constraints? Complete usually only assigns these constraints as a "last resort" if it can find no other way to constrain an element. A distance-constrained element may move along with other elements when it not intended to. Click the Show radio button and select Size and Distance to display any instances of these constraints.
An alternate way to check the constraints on your part is with Element and Icon in Inquire. For this example, you can use Element to see how Complete used the symmetry lines you defined to constrain components of the center circle:
1. In Parametric, click Inquire and then Element.
2. Click on each line in the dimensioned slot of the part. Notice how mirror constraints were extracted for each element in the slot. Try clicking on other components around the center circle.
3. In Generate Constraints, press Clear and select All Types. Then click End when you have finished with Inquire Element.
