Hello everyone!
This topic can be confusing sometimes, so I gave my best to explain it as simple as I could.
When it comes to SubD modeling you wanna stick to quad modeling with some exceptions on adding triangles in places where they do not cause deformations. Non SubD modeling, on the other hand, allows you to use any geometry type but has its restrictions.
P.S. Sorry about the typo mistake. It should say Motorbikes.
Hope you enjoyed the video.
Until next time,
Mario
Quad triangle designs are easy way to make in 3d modeling by the help of software it is easy now of days to make it on the other hand n qons in 3d model allows geometric ways to represent the 3d model although it is limited to some of sources.
