How to shadow in drawings

mark_cunningham

I have been trying to figure out how to shadow these letters  in Onshape for 3D printing actual emblems like this one. This is just an example.

close! maybe i can play with a little to get the 3d effect

It looks like you could use sketch text and then extrude with draft?  Then create a base plate below?

I hacked one method of getting extrusion at angle and then used parting line draft (only the 'S' because it is tedious to pick all the edges).  You just need to work out the angles.  There will be some distortion on the letter profiles but might be acceptable...   I am sure someone else can come up with a more correct and elegant way.

You can try the ExtrudeInDirection FS developed by some Onshape folks ( @lana, @Tim_Fries ).

Allows you to select an extrusion direction (like SolidWorks extrude) and, of course, draft.

Also, when selecting those edges for draft, don't forget the time-saver "create selection":

thanks for the link to ExtrudeInDirection; helpful to know about.  And the reminder on Selection!
In my trials the extrusion is good for the effect OP is after, but getting draft to work is another matter.
