Hello Michael,

Looks like there may be a bug in the view mesh angle.

Try this:
. start MoI
. create a circle
. planar it to create a disc
. delete the circle, just leaving the disc
. open the options and change the mesh angle to something silly like 100, the display updates to be very coarse.
. change the mesh angle to 10. Display updates again.
. save the file
. close MoI
. open MoI and the file again
. change the mesh angle to 100. Display doesn't update.

Hi Tony, yup that is a bug, thanks for reporting it. I've got it fixed up now for the next release.

There is a new display mesh mechanism which is meant to detect when a face has not been changed between operations, and just copy the face's display mesh over in that case instead of calculating a completely new mesh.

That's not fully working yet but once it is it should help to speed up operations that only affect a small area of a solid, the idea is to only calculate a new mesh for altered faces.

But this mechanism is kicking in accidentally in this case, when you actually want the mesh to be recalculated to match the new settings.

Righto, Michael,

In the meantime closing and re-opening the file does the trick :-)
