Measure Radius Surface Keep Con

Measure Radius Surface — Keep Construction

File: Part_Document_Scripts/Measure_Radius_Surface_Keep_Con.py
Version: 1.4
Document Type: Part (also works with Part inside Product or Process)

---

Description

Identical to Measure Radius Surface but keeps all construction geometry (intersection curve, datum points, fitted circle) in the part after measurement.

Requirements

Requirement	Value
Python	>= 3.10
pycatia	>= 0.8.3
wxPython	Not required
Open document	Part, or Part inside Product/Process

---

Usage

1. Open a CATPart document containing a surface to measure
2. Run the script
3. Selection 1: Select the surface to measure
4. Selection 2: Select an edge on the surface to define the measurement direction

   The edge must not be a closed curve

5. A message box displays the result
6. Construction geometry remains in a geometric set named MEASURE SURFACE CURVE AS CIRCLE

---

Output

A message box showing:

Radius: 25.43mm
Diameter: 50.86mm

If the surface is planar in the selected direction (points are collinear):

Radius: 0mm
Diameter: 0mm

Surface is Planar in selected direction
Points are colinear

A geometric set named MEASURE SURFACE CURVE AS CIRCLE is left in the part containing:

• Curve_Extract_Datum — the intersection curve datum
• Point_Datum_1/2/3 — the three measurement points
• Circle_To_Measure_Datum — the fitted circle datum

---

Notes

• The selected edge must not be a closed curve
• Results are rounded to 2 decimal places
• To discard the construction geometry use Measure Radius Surface
