Hi!

Playing with the app for the first time, and it is amazing! Running into something that I’m not sure what I’m doing wrong though.

I’ve extruded a model, and now in the corner of it, I need to cut through holes (for dowels). However, my sketch doesn’t let me be constrained against both edges at the same time.

![image](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex002/uploads/shapr3d/original/2X/c/c82e60b9beb1864daabafedd61e7426928d4b028.jpeg)

The picture shows what I’m attempting to do. Currently I can constraint against one edge or the other edge. But attempting to do both just… does nothing? After I specify the dimension for the second edge, it doesn’t do anything.

Any advice on what I’m doing wrong?

Object snaps would help here too 😉

That’s a bug that is already fixes in the beta. Fix is coming in 1-2 weeks.

Good to know, thanks!
