When resizing conical surfacegroups, built with radius #2 set to zero, Modeler will make that divided into chunks of surfaces and lines - sometimes with a following crash, sometimes not.

thanks for the notification.
In general, I'd advise to not use the conical tool with an inner radius set to Zero. This will create duplicate vertices for each surface and those are actually not allowed and are likely the cause for a crash.
Of course, Modeler shall prevent that dup vertices are created, so we'll pass this on to Engineering.
