Unwrapping a circular room in Spaceclaim?

That is a good one, one that even BIM software struggles with. I think sheet metal is going to be your best bet, I was able to unfold this shape.  I think your best bet would be to project the video display onto the sheet metal part then unfold that.  The only problem is that videos arent' going to be their true size of the displays anymore.  So you could project the center points of the videos points, then after unfolding it bring the video display components and placing then at the centerpoints on the flat surface.  If that makes sense.

Hi Dennis,

 

jepp, or maybe a bad one, if you need to solve it ASAP. ;O)

It appears SC can deal nicely with unwrapping bent sheets as long as no cutouts are made in the bent portion alone. I have experimented with bending (E.G. as per tutorial) and it all works fine as long as there are cutouts only in the middle of the bent area or in the flat parts.

As soon as one cutout in the bend touches the edge, it all goes wrong.

Try to pull the red surface in my version of your document through the wall ...

Huh. That seems to work for me. See attached.

Like I said before though assuming your video displays are flat and not curved with the wall, they are going to be slightly distorted when you unroll/flatten the sheet metal part. Although maybe that doesn't matter for what you are doing.

Strange, it does not work here, though.

I wonder what you did differently ...

Did you create the sheet part by pulling an arc from a sketch in sheet metal mode?

Yeah I placed an arc in sheet metal mode, but I had to made sure that "profile" was checked in the options dialog.

Hmmm... Sometimes the same things aren't identical, it seems. Thank you for your assistance so far, I'll have to leave the office now. I'll try again tomorrow with a new built model.

 

Best,

Martin
