This is awesome work. 
Amazing work dude! Learning a lot here 
Awesome, thanks for taking the time to include all the how to info.
Great Tips! thanks for sharing your insights
thks for sharing ur workflow and techniques. i always wanted to know how the pros do complex hard surface sculpting so fast. i learned a lot.
Really great breakdowns. Thanks man.
awesome sculpture! thank you for sharing the progress and the tuts!
Thanks P to take the time to show us this interesting tut!
Awesome Great work
The whole thread is a pure treasure of inspiration! Thank you so much Michael, I always enjoy watching your work.
great sculpt! and thanks for sharing some of your tricks 
I did follow your tuto. Thanks for that
But I have an issue. When I extrude the shape, the edges are not as smooth as yours (see the pict) Even after polishing by features
What do I do wrong.
Thanks for your help
Michel
I’d have to see your polygroups; first, mask and make a polygroup (mask, then ctl+w), isolate that polygroup, THEN run polish by features (open circle option). This should smooth out your edges, then bevel to your hearts content.
The problem is not coming from the first polygroup (the one that has been isolated and polished) which is perfect but from the polygroup around it. This one is making the bevel “broken” coz each polygone and triangle is making its self bevel meaning one hundred or more bevels instead of a continuous one. I don’t know how to fix it.
Ah I see. To make a perfect extrusion of your polygroup you have to use transpose modeling; here’s my transpose modeling video from the pixologic classroom:
http://pixologic.com/zclassroom/homeroom/lesson/transpose/#transpose-cable-creation-part-2
basically, have your polished polygroup unmasked with the rest of your object masked, click with transpose to find your the face normal (direction) you want to extrude the geo back, then…ctl+shift and drag the middle transpose circle inwards (I think it’s ctl, I don’t have zbrush open in front of me, and shift should constrain it to a straight line). Once you’ve extruded the geo, you can re-click your polygroup to make the transpose line start from the middle of the polygroup, then use transpose (scale) to shrink it inwards.
I appreciate your help. I think I get it now. I’ll post a pict when I’ll make it.
Thank you again for you taking time helping me.

I for one would love just the video timelapse if that’s possible. If you did commentary at a later stage that would be a bonus imo. Great work. Brilliant showcase for hard surface stuff in zbrush
Sorry for crashing in you post Michel. I had a bit of time this Sunday so I just did a very quick time laps of the clean extrusion technique in Zbrush.

Good Zbrushing to all.
Thank you very much elemmanuel. Now I get it “better”. This ZBrush is really full of tricks !!!
But so interesting !
No problem! I need to remember I can use Youtube for quick tutorials for follow up questions…it’s so much easier to show in a video than type out steps. The only thing I’d add is that you can hide polygroups and polish individual edges if you don’t want to polish entire surfaces. Great video!
