Janousek // [email protected] // www.scottjanousek.com // Creative Commons Now change to edges mode and select just the right side of the plane.

Janousek // [email protected] // www.scottjanousek.com // Creative Commons Now, with the edge selected pull it to the right until it’s big enough.

Janousek // [email protected] // www.scottjanousek.com // Creative Commons Here’s another isomorphic perspective.

Janousek // [email protected] // www.scottjanousek.com // Creative Commons Now control-tab to and select Face meshing.

Janousek // [email protected] // www.scottjanousek.com // Creative Commons Once selected, then use the Transform->Extrude region button, and pull the z-axis handle up to make the backplate have depth.

Janousek // [email protected] // www.scottjanousek.com // Creative Commons Now select the text in the scene, and extrude that up (since it’s also a mesh now).

Janousek // [email protected] // www.scottjanousek.com // Creative Commons Once the mesh is up, then make sure it is manifold and complete.

Janousek // [email protected] // www.scottjanousek.com // Creative Commons Add a bevel modiﬁer to the nameplate back.
