The '''TechDraw RadiusDimension''' tool adds a radius dimension to a View. The dimension may be applied to any Edge in the drawing which is a circle or circular arc. The distance will initially be the projected distance (ie as shown on the drawing), but this may be changed to the actual 3D distance using the {{Button|[[Image:TechDraw_LinkDimension.svg|16px]] [[TechDraw_LinkDimension|TechDraw LinkDimension]]}} tool.

Описание

The TechDraw RadiusDimension tool adds a radius dimension to a View. The dimension may be applied to any edge which is a circle or circular arc.

Measuring a circle, indicating the radius

Применение

  1. Select a circle or circular arc. The geometry may be selected in the 3D view or in the drawing. Note some arcs which appear to be circular are actually ellipses or B-splines. You cannot make a radius dimension in these cases.
  2. If you have selected geometry in the 3D view: add the correct TechDraw View to the selection by selecting it in the Tree view.
  3. There are several ways to invoke the tool:
    • Press the Insert Radius Dimension button.
    • Select the TechDraw → Dimensions → Insert Radius Dimension option from the menu.
  4. A dimension is added to the View.
  5. The dimension may be dragged to the desired position.
  6. If needed, add tolerances as described on this page.

Display 3D measurement

See TechDraw LengthDimension.

Change properties

To change the properties of a dimension object either double-click it in the drawing or in the Tree view. This will open the Dimension dialog.

Limitations

Dimension objects are vulnerable to the "topological naming problem". See TechDraw LengthDimension.

Notes

See TechDraw LengthDimension.

Свойства

See TechDraw LengthDimension.

Программирование

The Radius Dimension tool can be used in macros and from the Python console by using the following functions:

dim1 = FreeCAD.ActiveDocument.addObject('TechDraw::DrawViewDimension','Dimension')
dim1.Type = "Radius"
dim1.References2D=[(view1, 'Edge1')]
rc = page.addView(dim1)
