Analyzing Projections and Intersections

 
This task shows you how to analyze the elements resulting projection and intersection operations you explicitly performed but also from implicit operations.

You will be provided either a global or individual status and will be able to correct any problem stated in the status.
Open the Analyse.CATPart document.

  1. Select Tools > Sketch Analysis from the menu bar. 

    Or alternatively, click Sketch Analysis in the Tools toolbar (2D Analysis Tools sub-toolbar).

    The Sketch Analysis dialog box appears. It contains three tabs: Geometry, Projections / Intersections and Diagnostic.

  1. Open the Sketch Analysis dialog box again.

  2. Click the Projections / Intersections tab.


    The information on this tab displays a full diagnosis of a sketch geometry. It provides a global analysis of the sketch as a whole, and specifies whether individual geometrical elements in the sketch are  under-constrained (under-defined), over-constrained (over-defined) or iso-constrained (well defined):

    • Detailed Information: provides a detailed status/comment on each projection or intersection, on constraints and so forth.
    • Corrective Action  : according to the analyzed element you select and which is not correct, you will be able to:
      • isolate geometry
      • activate/deactivate a constraint
      • erase geometry
      • replace 3D geometry
      • hide all constraints on the sketch,
      • hide all construction geometries on the sketch and in the detailed information area of the Projections/Intersections tab.

    You can see that all construction and intersection elements for this part have a valid status so you don't have to do anything.
