I have been struggling with FredoScale in an attempt to extend this angled face onto an orthogonal plane. I have watched videos, read posts, etc. I would be very appreciative if someone could walk me through how to do this. Which option would be appropriate (See image)? Or maybe this extension will not solve this problem. Or maybe, there is a simpler solution (native SU tools?). And yes, I can brute force the solution by extending the lines, but is there a easier way? Thanks in advance.

The first line I drew was on the blue axis inside your component. If its axes hadnât been rotated you could have inferred a line perpendicular to the top sloped line.

Iâm finding it very difficult to get the inference on the top edge. I can hover it there longer than it takes to draw the whole thing the way I did above. Iâve only managed to do it twice in 10 mins of trying.

Select the end face â with the cursor over the long top edge press and hold down [Shift] â now move that selected face, grabbing it by its corner (the one on the same long edge) and move it to âOn Faceâ.

Added: taken that both faces (small and large) are parallel.

Thanks McGordon. You made an important point. Itâs all about the axes. I tried to change the axes but could not get the axes so I could simply pull the face. Need to spend time and understand the change axes tool.

I have tried to use âchange axesâ so that I can pull the face out, but cannot find a configuration that works. Is it possible to use âchange axesâ to solve this issue?

No, changing axes wonât make it easier. In my first reply, your axes settings actually made it easier for me to draw the line perpendicular to the sloping edge. If your axes werenât set that way, I could have got an inference perpendicular to the sloping edge instead. Thereâs no change of axes that would make that end face perpendicular to the long sloping edges. Either cut it off square first so you can use push-pull as I did, or use the move tool as shown by others.
