Performing a Quick Geometry Diagnosis  

This task explains how to display a quick diagnosis of a sketch geometry. You will be provided an overall status of the sketch geometry as a whole, so that can correct any constraint-related problem accordingly. 
Open the Sketch_Analysis.CATPart document. 

  1. Click Sketch Solving Status in the Tools toolbar (2D Analysis Tools sub-toolbar).
    .
    The Sketch Solving Status dialog box is displayed. It indicates the overall status of the sketch geometry. In this case, the sketch is under-constrained.
  • On the sketch as well as in the specification tree, under-constrained and over-constrained geometrical elements (lines, points, etc.) are highlighted, and iso-constrained elements are displayed in a different color. This enables you to see easily which items are under/ over-constrained, and which are iso-constrained.  
  • In our example, all geometrical items are under-constrained; they are therefore displayed in red. There is a tangency constraint which is iso-constrained; it is displayed in green. 
  • If you wish, you can click Sketch Analysis in the dialog box to view a more in-depth diagnosis specifying which individual geometrical elements in the sketch are under-constrained (under-defined), over-constrained (over-defined) or iso-contrained (well defined). 

  1. Click the Close button to close the Sketch Solving Status dialog box.

  2. From the specification tree, expand the Sketch.1 and then the Geometry nodes.

  3. Multi-select all items under the Geometry node, and right-click them.

  4. Select Selected objects > Fix from the contextual menu. All elements are now fixed.

  5. Click Sketch Solving Status again. The Sketch Solving Status dialog box now indicates that the sketch is iso-constrained.
