CAD Transform: Constraining along an edge

T by theoryshaw on 31 Oct 2020, edited 1 Nov 2020 #

When using the CAD Transform For Blender Addon and have a shape like the following...

...can you move the face (in red) and constrain it along the edge in blue?

Double click on G key, I think...

You may constraint a move operation by using

G, then C (constraint) and set the constraint axis the same way than for scale operations (pick origin, then pick direction)

Double G key will active edge slide mode, which uses a percentage. This is OK for percentage movements, but not if you want to move an absolute value.

If you want to do this accurately, you can use the custom constraints feature. This'll do it: (see 23:33)

Ok, Nice. I was doing the following...

G, clicking the point, and then C

but, it should be.

G, then C to assign the edge constraint, then pick the point to move.
