Diameter I Catia V5 __link__ -

"Fine," Elias said, gritting his teeth. "We do this the hard way."

| Scenario | Action | |----------|--------| | Change radius to diameter in sketch | Double-click constraint → uncheck Radius → check Diameter | | Show diameter symbol (⌀) in note | Type ⌀ or use <MOD-DIAM> in text editor | | Diameter of a hole in 3D | Use feature → its diameter appears in specification tree; no direct 3D dim unless annotated | | Diameter in Isometric view (drawing) | Works same as in orthographic views |

Elias paused. The old-school method. The "Best Fit" circle. diameter i catia v5

Most common use for final documentation.

He saved the file— Aero_Bracket_V5_Final_Real_Final.CATPart —and exported the drawing. The story of the part was over, but as he packed his bag, he knew tomorrow would bring another story: the tale of the faulty fillet on the mounting boss. "Fine," Elias said, gritting his teeth

Note that CATIA internally stores these parameters as RadiusX.object . Even if displayed as a diameter, any formulas or Knowledge Advisor parameters will typically reference the radius value. 2. Diameter in Part Design (3D Measurement)

He drew a rough circle roughly inside the projected loop, then used the tool. He didn't constrain the circle to the center—he constrained the circle to the walls . He used an advanced constraint: Radius/Curvature ? No, that was for surfacing. He needed a simpler trick. The "Best Fit" circle

He inserted a new definition. He defined a linear law that would govern the diameter along the sweep.

Note: True 3D annotations are saved with the part and can be reused in drawings.
