Each rule should be treated with the same amount of consideration. Here are 20 of my favorite “best practices” to follow when dimensioning CAD drawings in Fusion 360. Whether you’re new to CAD or an experienced 3D modeler, you’ll want to familiarize yourself with best practices for dimensioning CAD files.
