Creating Round Holes & Extrusions


1 Screenshot

About This File

Here's an epic 65 minute tutorial where 3DKiwi demonstrates various methods of creating smooth round holes or smooth round extrusions on objects.

Covered:

Simple hole in 4 polygons

Why using Booleans isn't a good idea

Holes and extrusions by copying in a disc object. Hard surface version and Subdivision surface variations demonstrated. Shrinkwrap deformer required. At the end of the tutorial 3DKiwi briefly demonstrates creating holes and extrusions with the "Make a hole" script by Sandi Dolsak, Cylinder to Cylinder II plugin by Jurgen Meier and a Nurbs version using MoI 2 and then exported into Cinema 4D.

Note: Instead of deleting polygons and then doing a Boundary Loop selection to find out how many edges there are a quicker way is to select the Polygons then do a "Select Boundary Outline" command. Hotkeys U~Q

Something I have wondered about a lot, but never thought of great enough import to go and ask someone. Thanks a billion!

Really very nice and useful!

Most of the manual steps are obsolete now after Nitromans release of his last amazing plugin MagicMerge!

This makes modelling much easier in many cases.

But still good to know how its done manually! :thumbsup:

Nitroman's MagicMerge plugin isn't really suitable if you are Sub D modelling. All it does is make using Booleans a bit quicker.

Absolutely stunning tutorial; well explained and documented; a must for every modeller.

Not only answers to "how" but even "why"..oh; and all of that for free.

Congratulations to the author.

I'm having a problem w/ the cylinder tutorial. C4D won't let me delete the polys created in the bevel step. It deletes the lines created by the bevel step but doesn't actually punch a hole in the cylinder.

Any thoughts on what I'm doing wrong? I'm guessing there's setting somewhere I'm missing.

I'm running R12 Broadcast.

Thanks

The MagicMerge does have some advantages.  Connecting simple objects and then beveling the edges is quick - joining 2 cylinders of the same size at angles works great.  I am trying to find the best way to create branching hoses in a natural way - think "arteries", "veins", "airways in lungs."  Many anatomical systems have branching pathways - so far, 3d Kiwi's tips for manually joining them have really helped, although the process can be s-l-o-w.  I have looked into plugins for creating trees, but haven't found anything that works!  If you have ideas, please share.
