Radius and Diameter Dimensioning (3-D)

3-D Dimensioning + Text > Individual dimensions

The Diameter dimensions and Radius dimensions functions enable you to create diameter or radius dimensionings of a circle or circular arc. You can, depending on the respective element type selection, choose edges or surfaces to dimension spheres, cylinders, tori and cones.

Example: Diameter dimension, axially parallel, via edge

Example: Diameter dimension, axially parallel, via surface

The following functions are available:

	Variable dimensioning Dimensions the diameter of a circle, the radius of a circular arc or the radius of a cylinder, cone, sphere or torus.
	New diameter dimension, axially parallel Axially parallel diameter dimensions of a circle, circular arc or a surface. In the case of circles or circular arcs, the dimension line lies in one of the quadrant points. The latter is determined by means of the point specified for the dimension line position.
	New diameter dimension, free Diameter dimensions of a circle, a circular arc or a surface, with free position of the dimension line.
	New radius dimension, free Radius dimensions of a circle, a circular arc, with free position of the dimension line.
	New radius dimension, axially parallel Axially parallel radius dimensions of a circle, circular arc or a surface. In the case of circles or circular arcs, the dimension line lies in one of the quadrant points. The latter is determined by means of the point specified for the dimension line position.

Please note:

• For all functions you need to identify an edge or surface first , and then determine the dimension line length.
• Before defining the length of the dimension line, you can switch dimensioning plane. To do this, press the right mouse button (END).
• If you fit a bore with a thread as a standard part and apply a diameter dimensioning, these dimensions are automatically created as thread dimensions. In this case, the symbol M (metric thread) is placed in front of the dimension figure, instead of the diameter symbol. If you want to switch off this thread designation and use the diameter symbol instead, change the relevant entry in the Configuration Editor (ISDConfigEditor.exe): Select ... > Drawing > Annotations > Dimensioning, 3-D > Interactive dimensions > ... Dimension figure and deactivate the Thread designation checkbox.

• You can use the mouse to rotate diameter dimensions about the centre point, and move dimension figures. The dimension will be placed once you have clicked the LMB. The same applies to parametric dimensions.
  The angle grid for the rotation can be specified via the dimensioning parameters, and refers to the dimensioning coordinate system of the original dimensions. To do this, select ... > Drawing > Annotations > Dimensioning, 3-D > Interactive dimensions > ... > Grid > Angle grid and change the value as desired.(Default 7.5).
