ChiefUserBigRob 16 Posted January 1, 2020 happy new year people! so, let's take this back to the basics. i want to create a 4" cmu block. i hatch it, the holes aren't subtracted. these are just polylines. how do the holes gets subtracted? Share this post Link to post Share on other sites
Dermot 573 Posted January 1, 2020 I think Eric's suggestion only works if you are using a polyline solid. If you are using simple polylines, the hole checkbox will not appear. Instead, just select the outer polyline, then click on the Polyline Subtraction tool, and then click on one of the holes. Share this post Link to post Share on other sites
