Impossible to change dimension

[ikbentheo]

In my model its impossible to change a dimension (active). After 2 tries, fusion360 crashes. It's not a weird dimension by any means.

Hi,

The polygon looks very unusual, how did you create it?
There is a special polygon tool for this.
Please upload the file for review

Hi Gunther,

I see the option now. I thought it was only for hexagons (because the icon), but now i found out i can change the amount of edges. Many thanks for this much faster way. I will try it that way.
