Circle Radius and Arc Length

[CraftyCat]

Tips please on calculating Circle Radius and Arc Length with dimensions.

[Kevin McAllister]

Often you'll need to add helper geometry if you're working in the Annotations space. I add geometry like circles and arcs in a class without fill or line colour. The Arc Length dimension tool is particularly difficult to use because its susceptible to finding other snaps unrelated to your arc objects and failing. I often group arc dimensions with my helper geometry and work within the group to minimize this happening.
