EXTRACTED REQUEST: HOW DO I DIMENSION THIS

USER MESSAGES:
1. HOW DO I DIMENSION THIS

ASSISTANT RESPONSES:
1. For that red horizontal distance, the clean way is: Dimension it centerline-to-edge as a radius location, or edge-to-edge if that flat is what matters functionally. In SolidWorks, I would usually do one of these: Best option for a formed/turned profile Use Smart Dimension from the centerline of the hole to the right outside arc, then make it a radius/center distance as needed. That defines the outer profile from the part center, which is usually more stable than dimensioning to a tangent-looking spot. If you specifically need that flat width Dimension from: - the vertical tangent point / virtual sharp where the straight wall starts on the left - to the vertical tangent point / virtual sharp on the right Becaus…

EXTRACTED KNOWLEDGE / HOW-TO
- *Dimension it centerline-to-edge as a radius location, or edge-to-edge if that flat is what matters functionally.
- Use Smart Dimension from the centerline of the hole to the right outside arc, then make it a radius/center distance as needed.
- the vertical tangent point / virtual sharp where the straight wall starts on the left
- to the vertical tangent point / virtual sharp on the right
- Start Smart Dimension
- Click the left arc/edge
- Click the right arc/edge
- Move the cursor below the view so it becomes a horizontal dimension
