I'm about 80% done with this opening, but I can't seem to figure out how to make the sill void clean up with the Jamb void. The Head and jambs are at 27 degrees and the sill is at 67 degrees. I created a sweep for the head and jamb then i created a void for the sill, everything is fine until i need for them to intersect and join. I can't seem to get a clean angled connection for the two to meet.

Has anyone achieved this? i have included some images for reference.

The redlines are what I want to achieve. I don't see any replies or suggestions, can Revit do this?

...can Revit do this?

Yes. See illustration. First you need a rectangular void extrusion to cut the wall through. Then, create a solid Sweep; the path is an inverted U shape drawn from the front elevation. The profile is drawn on plan or section, as shown. Then make a solid Extrusion; the sketch is drawn from a side view, as shown. Align and lock faces as usual. Then use Join Geometry to glue the two solids together.

Different Approach. First, you cannot have a void and an opening in the same family. You can nest the two, but really not necessary. You can create this as a generic or window family (in window be sure to delete the opening). Create a void blend and it will cut the wall as you want without any effort. To control, create reference planes height, width, front and rear surfaces etc. Be sure to lock front rear to wall faces, unless you want partially cut wall.


Attached is a VERY rough example. Maybe will give you some ideas.

However, the Blend solid void by itself will not be enough. Notice in the section view provided by the OP there is a flat sill and flat head inner portion in the opening, beyond the blend, which will require an additional extrusion void. Also, the Blend operation will require to know in advance the exact location and dimensions of the inner rectangle, which is not easy, since it is the result of the projection of some specific angles measured in the section view.

To each his own. Wasn't trying to design family for anyone, just showing that there is an alternate - anyway, here's one with TWO voids. You can have it six of one half dozen of the other... I have a family with the sweep designed in version 7, but was trying to encourage a little bit of exploring alternates. Each design problem has its own set of "knowns" and approaches. Design the family right and you don't need to know opening sizes, angles etc. You can flex the design however you approach it most of the time.

Thanks Guys,
I was looking at this the wrong way. I was trying to have a void create my profile, but now looking at the suggestions, I have seen the light at the end of the tunnel. Just took me one full day to try to figure it out.

in both my examples, the void did shape the profile, there is nothing wrong with that approach. Revit gives you that flexibility.
