Circle, Radius and Diameter Dimensioning (3-D)

3-D Dimensioning + Text > Circle

This function enables 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.

The following functions are available:

Circle/Radius dimensions, Variable

Dimensioning for the diameter of a circle, the radius of a circular arc or the radius of a cylinder, cone, sphere or torus surface with free position of the dimension line.

Depending on the identified object, HiCAD determines the diameter or the radius dimension:

If the identified edge is a circle, the diameter dimension is created.
If the identified edge is a circular arc, the radius dimension is created.

In the case of surface dimensioning, the radius dimension is created.

Left: Diameter via edge, Right: Radius via surface

Circle/Radius dimensions, Axially parallel

Axially parallel dimensioning for the diameter of a circle, the radius of a circular arc or the radius of a cylinder, cone, sphere or torus surface.

Depending on the identified object, HiCAD determines the diameter or the radius dimension:

If the identified edge is a circle, the diameter dimension is created. The side on which the dimension is created depends on the cursor position when identifying the edge. The ends of the projection lines lie in the quadrant points of the identified circle.
If the identified edge is a circular arc, the radius dimension is created. In this case, the nearest quadrant point is determined, starting from the point specified for the dimension line length. The dimension line goes through this quadrant point.

In the case of surface dimensioning, a radius dimension is created.

New diameter dimension, free

Diameter dimensions of a circle, a circular arc or a surface, with free position of the dimension line.

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 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.

Clicking

opens a menu with the functions for axially parallel dimensions.

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).
