Hello all I'm still learning Blender and I am stuck understanding the best way of adding some extruded parts to the top of my mesh. Im modelling a Glock 17, its fairly blocky so thought it might be an ok mid-project (i've made stuff such as Bottles, cups, tables etc and even made a pretty decent car which took me forever and probably had lots of 'errors' in the mesh.)

Anyway as you will see in the picture, I want to add a bunch of splits in the top rear part of the gun barrel. I could do this by adding some loop-cuts running vertically where i want the slices to appear. But this will run lots of unnecessary loop cuts into the lower barrel and handle of the gun.

What would be the best way to avoid these loop cuts?

  • $\begingroup$ The area which has those riffles is separate part covering the top of the gun and which actually moves when sleeve shoots out sportsmansoutdoorsuperstore.com/prodimages/40606-DEFAULT-l.jpg. So model that top part as actually separate mesh from the bottom, which is a nice rule to keep in mind for other cases $\endgroup$

  • $\begingroup$ ok thanks, i did know that already but I was trying to keep it simple for now. Lets pretend it wasnt a separate object, how would one acheive this grill type feature in the metal?. (Note: I ran into similar problems with the car i made which is why i went back to start some fairly simple , blocky objects) $\endgroup$ Oct 25, 2018 at 21:59

It is not ideal to do what you are asking because you will most likely have to triangulate your mesh.

I recommend going with the loop cut, finishing your model, triangulating it (control-t), then decimating it down without losing quality (Note: Decimate is a modifier :D ).

But if you insist on doing it now:

Make the loop cut and select the vertices you don't want.

Double press G to slide along the edge and move it on top of the next edge.

Press W and select remove doubles.

If you have done it properly, there should be a single triangle in the middle of your mesh.


Good luck with your project and I hope I helped,


  • $\begingroup$ thanks for this helpful info. i only just came back to read it but once i get modelling again I will surely check out these techiniques. cheers !! $\endgroup$ Nov 1, 2018 at 0:35
