Angles (HCM 3-D)

3-D Standard > HCM > Distance > Angle...

To access the Angle functions, select 3-D Standard > HCM > Distance . In the pull-down menu you will find the following two functions:

• Angle, 2 elements
• Angle 2 elements, min./max. value

Use the functions of the context menu to set angle constraints to coordinate system elements, in the same way as you would do for geometry elements of the drawing. You call the context menu by right-clicking after selecting the first geometry.

Context menu

The context menu functions enable you to set an angle constraint between a selected geometry element and

• the X-, Y- or Z-axis (= same as an edge), or
• the XY-, YZ- or XZ-coordinate plane (= same as a plane in the drawing).

Choose Step back to undo the last action, and select Cancel to abort the process.

Right-clicking the HCM item in the ICN or the dimension element in the drawing opens a context menu containing the Invert angle normal function. Select this function to assign the opposite direction to an angle constraint.

Angle, 2 elements

3-D Standard > HCM > Distance > Angle, 2 elements

Use this function to specify the angle between the directions of lines, cylinders or planes. These directions are unbounded, with the result that the angle is always between 0 and 180 degrees.

1. Identify the geometries to which you want the angle constraint to refer, one after the other. Take into account in so doing that the angle will be measured anti-clockwise from the geometry that you have identified first.
2. Place the angular dimension dynamically using the cursor.
3. Apply the required position with a left-click.
4. Then specify the angle.

Before applying the position you can activate the Dimensioning, Move context menu with a right-click. In the context menu, the following functions are available:

	Dim. figure + Dim. line	Free moving of dimension line and dimension figure with the cursor
	Dimension line	Free moving of the dimension line (default)
	Dimension figure, parallel	Moving of the dimension figure parallel to the dimension line
	Dimension figure, free	Free moving of the dimension figure
	Switch to ZX-plane	Switching to the ZX-plane of the active dimensioning coordinate system
	Continue	Back to the Angle function

Note: Instead of entering an angle of 0 or 180 degrees, you should preferably use the parallelism constraint, as the calculation overhead is smaller.

Angle, 2 elements, min./max. value

3-D Standard > HCM > Distance > Angle, 2 Elements, min./max. value

Use this enhancement of the Angle function to assign a maximum and a minimum value to an angle.

First identify the two geometry elements to which you want to assign the angle constraint (Please note: Use the right mouse button to get detailed options for geometry definition).

Next, you will be prompted to specify the minimum and maximum value.

You have now assigned an angle constraint with a defined area to these two elements. This defined area must not be exceeded, e.g. when performing motion simulations.
