01 When to use caps

3D World - - TUTORIALS -

When start­ing to ex­trude with a sim­ple poly­gon, al­ways think about if caps are needed or not. A cap is a copy of the poly­gon that is be­ing ex­truded, and which fills the hole at the end of the new ex­truded shape. It may seem log­i­cal to add a cap if a solid ob­ject is be­ing made, but this isn’t al­ways the case es­pe­cially if the mesh is to needs to be sub­di­vided later in the mod­el­ling process. Make sure that you check the at­tributes or prop­er­ties of the tool to see how caps can be added.
