•DesignModeler is primarily intended to provide geometry to an analysis environment.  For this reason we need to see how DM treats various geometries.

•

•DesignModeler contains three different body types:

–Solid body: Body has surface area and volume

–Surface body: Body has surface area but no volume

–Line body: Body consists entirely of edges, no area, no volume

•By default, DM places each body into one part by itself

•Individual parts will always be meshed separately

•If bodies in separate parts share faces, the meshes
on those shared faces will not be matched

•Multiple bodies in a single part will have matched
meshes on shared faces when meshed

•By default, DM will merge new geometry with existing
geometry to maintain a single body

•This can be controlled by working with either frozen
or active bodies

•You can toggle between frozen and active states for using the Freeze and Unfreeze tools
