Draw Negative of Arc?

Recommended Posts

I need to cut the end of this rafter so that it has the rounded profile as shown. How is this done?

If this is 2D (and maybe even 3D), you can use the Fillet tool.

 

Alternatively,  do a 2-step process to make a "cutting shape".  Since the positive arc is much easier to draw, Draw a slightly bigger than needed square or rectangle and draw the arc on top. Select both and Clip Surface. This will give you the "negative" shape you are looking for. Place this shape over your rafter and Clip Surface again (if you have more than one, you probably want to duplicate your "cutting shape" first so you don't have to recreate it).

 

If you are in 3D, you can do basically the same thing, but after you make the negative shape, extrude it. You can make it way over length so it is easier to align with your 3D rafter. Then select the 3D cutting shape and the rafter and Subtract Solids.

 

And there are probably several other easier ways that I am not thinking of right now.

 

Ask again if these are not clear enough.
