| Summary | 0001828: Sketcher slot has broken constraints after creation sometimes | ||||
| Description | When creating a Slot shape on a sketch, the resulting geometry sometimes confuses the solver. Symptoms vary: approx 1 of 10 slots drawn is reported to have more than 4 degrees of freedom (I've seen numbers as high as 8), and very occasionally, the slot is not movable by mouse. | ||||
| Steps To Reproduce | 1. create a new sketch 2. click the slot tool on the toolbar and arbitrarily draw a slot with the mouse. 3. look at the number of reported degrees of freedom. 4 is the correct number, the bug is vhen it get higher than 4. 4. (if dof=4) delete the slot and draw a new one. Keep doing this until you get dof>4 5. (for fun!) drag the slot by one of the tangency points and observe the broken coincidence (sometimes). The coincidence is typically restored on the release of the mouse button, and dof becomes the normal =4. | ||||
| Additional Information | The slot typically becomes normal after being moved e.g. by mouse. A guess for the cause: Tangency of line to arc and coincident's Y part should appear redundant in the Jacobian matrix. If so I wonder why isn't it reported.
