Summary:
As I’m sketching a somewhat-uniform shape, I have to explicitly draw the thickness of it.
I have to draw each edge of the thickness, which is double the work and making sure I don’t make mistakes.
I wish there’s a way to sketch a single line, and then EXPAND it in both directions of its norms, ensuring it’s very accurate and uniformly symmetric.
Details:
Consider this sketch below (top portion). I’m sketching over an image to copy the thickness of the shape (which I will later extrude into a body). Notice the red arrows point at all the lines and arcs I had to draw, which add up to six (2 lines on the left, 2 arcs, then 2 lines on the right).
Now imagine there’s a feature where I’m sketching like the screenshot above (bottom portion). I sketch just one version of the shape in its center – 1 line on the left, 1 arc, then 1 line on the right.
Then, I click whatever EXPAND button that I drag over my sketch, and it instantly clones the line into two copies in the direction of its norms, to achieve the thickness I need based on just a single line.
Imagine how much time this will save you that you can sketch ONE continuous line of your entire shape, and instantly give it thickness.
