How can I measure the overall length of a 3D Sketch?
If you open the Measure Tool, and then identify the sketch, you will have to manually select on each sketch segment comprising the total length. For reasonably complex sketches, a much faster method is as follows:
Edit the 3D sketch. Activate your Selection Filter, and set it to only select Sketch Segments. (This is done to avoid getting any sketch points, which have zero length). Now group-select the entire sketch by dragging a "bounding box" around all elements. [Or you could instead right-click on one sketch element and choose Select Chain.] Now that the desired elements are pre-selected, open your Measure Tool, and the overall length is already computed.
