hello,

 

i've run into a problem working in sw 2017. usually i can figure it out myself, but this time there isnt even a solution on google.

 

i am trying to cut a blind m3 hole on the concave side of a pipe. however, when i try to do so it gives me the ztg error. i've tried the following:

 

- restart sw

- flip offset of reference plane

- tried different commands (hole wizard normal hole, through all, extruded cut.)

- dramatically increased wall thickness

- recreated the sketches and planes over and over

- work in a part instead of assembly

- preselect the reference plane

- tried different hole depths

 

on the convex side i can do all these commands. and even if i select through all, it gives me the ztg error

 

this has taken me hours already. any help would be appreciated

 

here's a screenshot of the part:
