Nice. Ok just so I understand, this is your outlining of the circumstance that leads to this, right? There's not an expectation that the shape that serves as an extrusion's inspirations be moved around _with_ the extrusion, right?

Maybe there is such an expectation.

As you had drawn it, I attempted to make it work with the underlying door rectangle at 90 deg to the plane but failed. Nothing I did would make the cut work. The moment I rotated the door shape to lie along the plane (and subsequently corrected the extrusion), the cut as expected seemed to work.
Maybe there is a need to have a separately aligned extrusion inspiration for each extrusion plane.

Roy_043 in the previous post (and currently I agree with him having re-looked at your first post house available to download today) suggests, there is possibly some underlying issue not presently evident that stops the cut working. Like Roy says the cut isn't working.

I'm off to retest separately various panel cuts with plain rectangle inspirations for cut extrusions with the inspiration inline or at 90 deg to the intended cut panel to see what currently works. I've always placed the inspiration, with the resultant extrusion straddling the object plane where I need the cut. Maybe rightly or wrongly in that line of action.

Hope this helps.

Hi OverkillTASF,

The plot thickens. I've been idly watching telly and trying out some combinations of Inspiration (underlying rectangles), subsequent Extrusions and an Arch Remove cut on a Panel. See attached file.

I've left all the rectangular inspirations and cut extrusions visible in the file so it is easy to see the alignments and separations.. Also I tested inspirations aligned to the panel plane and at 90 degrees to the panel.

The key takeaway I've noticed is that if the underlying inspiration is separated from the extrusion, the cut fails or is misplaced. This unfortunately seems to confirm the expectation that the extrusion must follow / be coincident with the inspiration for a successful cut. Probably not the result you expected or wanted. Alternatively, I've have not experienced such issues because I've always positioned the inspiration with each extrusion.

Hope this further helps. It has certainly has increased my knowledge in this area.

Cheers. PMac

Now I'm having issues moving Beam077 vertically. It will become an LVL header for the garage door span, but I'm unable to move it up or down... Still running 22336.

That's gotta be a bug! If multiple extrusions are based on / inspired by one "profile" shape, which one should the profile move around with? In any case the `Difference` tool seems to do the trick.

Ah, oops. I had done some parametric-stuff in the position of a window header and copied a window header to base this one off of, and forgotten. So the Z was set to a specific height based on other measurements. Resolved!

Last bedroom window framed, header placed (until structural engineer has better details) on four uh, cripples I guess. Note that the sole plate and all of the vertical framing/windows in that section will be removed when it comes time to convert to "garage" mode. Planning for that, while also still trying to get 4' centers for my sheathing to land on was a little frustrating...

Panic this evening... I threw together a 2-shipping container storage area that I need to get a building permit for... and I'm having an incredibly difficult time getting section views to work appropriately. I end up with items missing, weird render errors... It has me very worried that all of this work will result in something presentable... Is it folly to try to have my elevations and whatnot rendered in techdraw sheets? What stage is best for adding dimensions?

Added wallboard all around.

Now it looks much more boring given all the work that went into framing, but that's life I guess.

At this point I'd like to draw the interior rooms just as non-structurally accurate walls. I find Inkscape is a lot easier to do this, and that's where I did my first original plan. Drawing a wall and up against another wall and then bumping it X inches down without worrying about 3d space is a better workflow when doing floor planning. But I guess I'll try to do it in the draft workbench....

Still really worried about getting the cross sections out of this that I'll need when I submit it to the planning dept...

Found a problem with the rear wall wallboard... went in to fix it... and also discovered that when you move a panel that has had a subtraction done on it, the volume you used for the subtraction also is moved. Which is really unexpected.... at least in this use case.

Added a window I forgot about, made a few small tweaks, and added some section views for the walls/windows.

Not suuuuuper happy with the flexibility of the section views... For instance I'd like to be able to cross hatch cut areas as is the convention. Not sure why the defaults make cut lines BOLD either... but with some tweaking I can get that to look basically right. Adding dimensions here is a lot harder and weirder than I expected, as is adding callout lines and labels... maybe I'm missing something.
