I wish\request the ability print a solid diaphragm at a given layer. Or more than one layer preferably: A field that allows me to enter any number of layers to do a solid diaphragm in.
This is to help with the chimney\flat roof problem. Which I will exaggerate here, but it will make the point clear. This is also shown in the S3D troubleshooting guide here: https://www.simplify3d.com/support/prin ... or-corners
* Pretend you're printing a house with a flat roof, and a chimney in the middle sticking straight up. Or a big cube, with a little cube on top, both touching.
* You're printing with zero infill.
* When it comes to print the roof of the house, S3D will make a hole under the chimney in the process (because it's a solid volume suitable for 3d printing). But since there is no infill, the roof layer will completely fail in the middle as it doesn't have the ability to create a complete bridge across (due to the hole made for the chimney.
* Chimney falls into the house (figuratively and literally)
Ok, so you can add infill of course. But you'll still
encounter this issue on the perimeter of the chimney where it doesn't overlap with the underlying infill. Happens to me all the time: You get these gaps\holes at the corners of the chimney where it touches the roof. The only real solution provided is to both up the infill, and up your 'roof layers' in the software to compensate. Which is wasteful for a number of reasons. It would be nice if the software itself detected for these issues and auto-added the underlying internal supports, but I don't see that happening any time soon.
If you could simply specify that at "layer 239" to have a solid diaphragm printed, it would solve this: It would print a completely solid layer just before the chimney starts, and the whole problem goes away.
I do have a workaround for this: I found (what I would consider) a bug in the software, documented here:
The issue is, whenever you make multiple processes, S3D always inserts a solid diaphragm between them. So, If I start splitting my processes up to start\stop at the chimney line, the software handles this solid diaphragm for me. But this is incredibly clunky.
So again a request, probably in the Layer tab, to specify which layers could be printed completely solid. That'd be awesome!
