03 Ex­trude Groups

3D World - - TUTORIALS -

There is a dis­tinc­tion be­tween some 3D ap­pli­ca­tions about how in­di­vid­ual poly­gons are ex­truded. While all soft­ware will ex­trude a sin­gle poly­gon and associated edge loops, some soft­ware can ex­trude the se­lected poly­gons as in­di­vid­ual ex­truded el­e­ments with their own walls. This can be use­ful, for ex­am­ple, when ex­trud­ing fin­gers. It is best to use this kind of ex­trude with a scale op­tion as oth­er­wise the walls of the ex­trudes could cre­ate con­flicts later in the mod­el­ling process.
