Users should not be afraid of moving sketch entities around to find missing dimensions or geometric relations. Any changes that may break a sketch can be easily undone with the Undo button above the sketch area.
However, if a segment of a sketch appears blue, indicating the segment is under-defined, it can’t be moved. Displaying identity points can provide clues when searching for missing dimensions and relations.
Under the Tools menu, select Options and then enable the Sketch category. A checkbox will become visible titled, “Display entity points in part/assembly sketches.” Checking and accepting this change will reveal the end points of all line segments within the sketch.
In the video above, a vertical line appears in blue. After displaying entity points in the sketch, the under-defined segment can be dragged. Reapplying its vertical geometric relation fully defines the segment.You can continue to develop your CAD, CAM & BIM skills by signing up for a free membership at http://www2.solidprofessor.com/engineeringfreetrial.
