Crash when using Loft and setting Takeoff Weight

[jenschrDRCX6]

Just did a simple loft of 4 circles into a tube. By accident, I entered the number 2 in the field "Takeoff Weight" and got an instant hang. Could it be that this number should be between 0 and 1, but it's not enforced?

No, the takeoff weight can be above 1.  Takeoff weight, in your model, is only being applied to profile 4 since you have it declared as "Direction".  If you add an angle also, the weight is the emphasis that the angle is applied.  This is sort of like if you pressed your hand down on a flat surface with a stronger force making it flatten out more.  Model is attached.

@jenschrDRCX6 - how long did you let it run?  Loft can be expensive to compute, and what may appear to be a "hang" is just a complex operation taking a long time to compute.  If you share the design here, and provide enough info (screencast, etc) to reproduce the problem, we'd be happy to take a look at it

It was 4 circles, so not very complex. I killed it after 7-8 minutes of the "ball of death" spinning on my Mac. Shouldn't take that long. Took less than a second after recovering the file (love that feature!) to redo the loft. If I did not change "Takeoff Weight" it was stable.

Even with 4 circles, the math can still be quite complex, especially when you factor in things like takeoff weight.  Still would be interested in seeing the design to see if it really was a "hang", or if would have eventually succeeded (or even failed).
