Did you use a triangle model for your initial block? I've had this happen when i import my block as a step file sometimes. it could be because the step model is not a true (watertight) solid, or it had some anomaly when exporting/importing it. The only fix I've found is putting that block in powershape, make sure its a true solid with no faults and export it as a dmt file. 99 times out of 100 this solves it.&nbsp;</P> Tue, 18 Oct 2022 14:30:33 GMT https://forums.autodesk.com/t5/powermill-forum/ghost-triangles-on-stockmodel/m-p/11490821#M5259 TK.421 2022-10-18T14:30:33Z https://forums.autodesk.com/t5/powermill-forum/ghost-triangles-on-stockmodel/m-p/12532639#M5260 <P>I've been having this problem a lot lately. After reading this I brought my DMT file into Powermill Modeling and could clearly see the holes, big holes, in the file. Can I heal an STL or DMT in Powermill Modeling?</P> Wed, 31 Jan 2024 19:46:54 GMT https://forums.autodesk.com/t5/powermill-forum/ghost-triangles-on-stockmodel/m-p/12532639#M5260 Beta_Librae 2024-01-31T19:46:54Z https://forums.autodesk.com/t5/powermill-forum/ghost-triangles-on-stockmodel/m-p/12533118#M5261 <P>I don’t believe so.

I was afraid you were gonna say that.
