Performing a Quick Geometry Diagnosis

You can display a quick diagnosis of a sketch geometry. An overall status of the sketch geometry as a whole is provided, so that you can correct any constraint-related problem accordingly.

Before you begin:

Create a set of elements similar to the one below.

Setting Constraints

  1. Click Sketch Solving Status in the Tools toolbar.

    The Sketch Solving Status dialog box appears. 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.

  2. Click Close to close the Sketch Solving Status dialog box.

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

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

  5. Select Selected objects > Fix from the contextual menu.

    All elements are now fixed.

  6. Click Sketch Solving Status again.

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

    Important: In the Find dialog box, Advanced tab, you can search for existing sketches in a given workbench by selecting Solving Status in the Attribute list. It allows the search of sketches according to their status of solve. The Attribute Criterion dialog box is displayed with a list of attributes. The example below shows a list of criteria corresponding to a sketch type:

    Tip: 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).
