The most common mistakes are: wrong selector axis, deleting points too early, not trimming after fillets, and ignoring the canvas preview warning.
| Mistake | How to Avoid |
|---|---|
| Using XLarge when both intersections have the same X | Use YLarge/YSmall when solutions differ in Y, not X |
| Deleting a point before geometry built from it is complete | Only delete points after all product geometry is baked |
| Not trimming after creating fillet arcs | Always trim corners after creating fillets |
| Trimming before all fillets are created | Create all fillets first, then trim all corners |
| Assuming the canvas preview is the final result | Always verify position after committing |
