I need to make a pair of eye glasses and would like to be able to do it in Zbrush. Does anyone know if it can be done and where would you start. I have tried to do it with Zpheres and cube but no luck.
Yes, it can be done. I would probably do it as handful of subtools.
The earpieces I would mold from rectangles.
The lenses would be flattened spheres.
The frame might start out as a couple of torus shapes and a bridge to join them might be any old blob like a flattened sphere or rectangle.
It depends on how detailed you want to get. You might take a look at my blog (linked in my sig)–I’ve been running a series on mechanical modeling in ZB3.
The tradeoffs will likely involve how efficient you want to be. A pair of glasses in a SubD modeller might only be a few hundred polygons (sans detail added in maps later) while you might use a lot (hundreds of thousands) of polygons to create very detailed shapes (again depending on how much detail you want.)

Kerwin thanks for the info. I see how it work the best to subtool it. Oh ya very nice site you have.
the question is not whether you can do it- but whether you SHOULD do it. It would be a slow inefficient process that a poly modeling program could do efficiently in 15 minutes.
if you are just going to use it for an illustration and polycount and topology is not an issue than you could do it probably in under a minute by making a cube and or sphere, draw the glasses shape on as a mask and do an extraction.
@testure I am just trying to see what zbrush can do. I look at a pair of eye glasses as a small job in my other CG tools. But I find in zbrush small easy models are to time intents to do. But spaceboy412 said it can be done faster here.
@ spaceboy412 Could you do a time lap video of your way of doing a pair of eye glasses? Just normal round lens and arms that curve at the end over the ear.
i used Alpha 09 as a mask, and an extraction on a polyplane of 1mil polys. and was very lazy and imprecise with the arms but whatever.
then used transpose to move the arms back. if i had drawn the mask on a cube i wouldn’t need to do that.
took less than 3 minutes, sorry no vid.
yes its fast and ugly, but for an illustration it would be fine. you didn’t specify what the outcome is needed for and that dictates much of ones workflow.

spaceboy412 thanks You hit on a way that I never look at. I was trying to make something hard out of a simple thing.
I am trying to see how will zbush model will work out in a small animation and I am pushing the polys up so the detail will be there in the video. Thank again for your help in making me see that in zbrush, look at it as a simple model and for the easy way of doing.
i would not suggest the above method for animation, the poly count is way higher than it needs to be for something like that. you would be better off making them in another app or using zspheres or lastly retoplogizing what i made so you’d have a lower res model.
Thanks for that info I will keep it in mine. It is just a test I am doing using zbrush. I hope to hit 3 mill ploy in the animation per human model
