Re: sheet metal half-shear button

In the sheetmetal, use sketched form, change type to "piercing" instead of "punched" (2nd icon in the ribbon).

Then just sketch a circle...

Re: sheet metal half-shear button

BTW ... I tried to do a "sketched form punch" .... it made the small half-punched hole in the front surface, but creates a larger (added sheetmetal thickness) plug diameter on the back surface.    Hole diameter in front and plug diameter in back should be the same on a half shear button

Re: sheet metal half-shear button

Not sure what you mean by a half-sheer button, but how do you punch material and get the same diameter on both sides of your sheet?  The material has to be deformed someplace and I would expect the back side to be larger than the punch by the material thickness.

Re: sheet metal half-shear button

A half-shear button is a common sheet metal practice used for accurately locating parts prior to spot welding   ….. it basically punches a hole at half-depth on the front surface while creating a plug, of same diameter, at half depth out from the backside surface.

I’ve been able in the past to create this on solidworks sheet metal parts with just a two step process …. 1) create a hole at half depth on the front  2) create an extrusion out the back   ……………. But I can’t seem to do it in CREO
