I've seen how patches can be used to create some basic curves, and how things like cones and cylinders can be created with brushes.  I am curious about how I can create some other curves - say I want a 90 degree curve, ie, and end-cap cut in half.  How can I create this?  I see that I cannot cut patches.  I'd also like to figure out how to create a cylinder with a hollow interior, and also a hollow half sphere (dome) or quarter sphere (half-dome).  I've seen most of these in various FMs so it is almost certainly doable in DR, but I'm at a bit of a loss.  Thanks in advance!

I am not sure if I understand correctly, but I recall a thread about cutting patches:

I hope this is helpful.

Yes, you can use the Scripts -> Split patch to make half- and quarter-domes.

 

I'm not quite sure what 'a cylinder with a hollow interior' is asking for (anything made with Patch -> Create Cylinder will be hollow, unlike a brush prism), but if you want the cylinder's surfaces to face inwards you can do Patch -> Matrix -> Invert, and if you want both inward- and outward-facing surfaces without a twosided material, you can copy the patch and matrix-invert the copy.

 

The 'end-cap cut in half' sounds like the Bevel option in the cap selector.

Thanks, guys!  I didn't know about the inverted patches.  A 'hollow' cylinder I meant would be like a solid cylinder with an empty cylinder inside it, if that makes any sense - like this:

Ah, I see. For something like that, try making a basic cyllinder and then using Thicken Selected Patches with the option to create seams ticked.

I would recommend checking the Wiki. Starting with http://wiki.thedarkm...p?title=Patches When you type Patch in the search field there are several suggestions on special uses of patches as well.
