The attached video shows an inconsistency that I can’t figure out … have redone the operations three times now, getting the same result. I was trying to create a simple slab the with the same width of the more complex part in the model.
So: I selected the edge of the existing part to get the desired dimension. Then I drew a rectangle, and used the extrude tool to extrude it to the same depth as the dimension of the edge I had previously selected. The result is the two objects in the video. The video shows me selecting the edge of the original part (80 mm), then selecting the edge of the extruded part (also 80 mm), but by rotating the model it is clear that the two parts are not at all the same dimension. If I move the slab into an intersection with the other part, and subtract the two, or intersect the two, the result shows that the parts are different dimensions.
What am I missing here? Or doing wrong? Or is this an issue?
Thanks in advance!
