Crosshairs (3-D)

3-D Standard > Tools > Crosshairs, Bore/C-edge

Use the Crosshairs, Bore/C-edge function to create crosshairs by

• specifying one or several boundary edges (depending on bore / C-edge type) and
• specifying the start point of the crosshairs (for the size). Press the middle mouse button to apply the point suggested by HiCAD, e.g. the 1st quad point of the circle.

(1) Selected boundary edge, (2) Quad point selected via MMB

Clicking opens a menu with further functions for the creation, deletion hiding and showing of crosshairs and surface axes for various 3-D elements.

• Crosshairs, Slot
• Crosshairs, Rectangle
• Crosshairs, Hole pattern
• Crosshairs, Sphere/Torus
• Axis, Cylinder surface
• Axis, Via 2 points
• Delete axis
• Hide axis / Show axis

Please note:

• The Axis, Cylinder surface function creates the surface axis for a cylinder surface or for the polyhedral facet of a polyhedronized circular hole. It applies similarly to cones, toruses and spheres. The symmetry axes are created for the torus and cone and, for the torus, additionally also the centre circle (large radius).
• For crosshairs and axes, a feature log entry called Crosshairs or Axis will be created. This entry will be assigned to the part to which the surface selected with the corresponding function belongs.
• Each operation has its own UNDO step.
• If an assembly or main assembly is active when you call one of the functions, an insertion of axes will not be possible. In such cases the following message will be displayed:

Crosshairs, Slot

Creates the crosshairs by selecting 2 edges of the slot.

(1) 1st boundary edge, (2) 2nd boundary edge

Crosshairs, Rectangle

Creates the crosshairs by selecting 2 edges of the rectangle.

(1) 1st boundary edge, (2) 2nd boundary edge

Crosshairs, Hole pattern

Creates the crosshairs by

• Specifying the centre point of the hole pattern.
• Selecting 2 neighbouring bore circles.

(1) Centre point, (2) Bore circle, (3) Neighbouring bore circle

Crosshairs, Sphere/Torus

Create the crosshairs as follows:

• Specify the sphere/torus surface by selecting 2 edges.
• Specify the start point of the crosshairs. Alternatively, you can apply the point on the sphere or the torus suggested by HiCAD by pressing the middle mouse button.
• For spheres you need to specify another point.

(1) 1st edge, (2) 2nd edge, (3) Point on torus via MMB

Axis, Cylinder surface

Creates an axis by selecting a surface via two edges.

(1) 1st edge, (2) 2nd edge

This function creates the surface axis for a cylinder surface or for the polyhedral facet of a polyhedronized circular hole. It applies similarly to cones, toruses and spheres. The symmetry axes are created for the torus and cone and, for the torus, additionally also the centre circle (large radius).

Axis, Via 2 points

Creates an axis by specifying 2 points.

• Select the body in the drawing, or select the active body via right-click.
• Then, specify the start point and the end point of the axis.

(1) Selected part, (2) Start point, (3) End point

Delete axis

3-D Standard > Tools > Crossh. > Delete axis

If one of the Delete crosshairs functions is applied to a crosshairs that has been automatically created by a different function, e.g. the insertion of a bore, this deletion will not be entered as a new feature, but as a sub-entry called Delete crosshairs beneath the creation feature:

In this way this change will also be preserved in case of a recalculation. To undo this processing later, right-click the Delete crosshairs entry and choose Clear.

Hide axis / Show axis

3-D Standard > Tools > Crossh. > ...

The hiding of the axes is recorded in the Feature log in the form of an entry called Hide crosshairs.

If one of the Hide axis functions is applied to axes which have been automatically generated by a different processing (e.g. after insertion of a bore), this step will not be entered in the Feature log as a new feature, but as a sub-feature of the creation feature. In this way it is ensured that hidden axes will actually remain hidden after feature recalculations.

If you want to redisplay individual axes / crosshairs, right-click the Hide crosshairs entry in the corresponding feature and choose Clear. The corresponding feature entry will then be deleted.

To redisplay all axes / crosshairs of the active part in one step and simultaneously delete the corresponding feature entries, choose the Hide axis - All in active part function.
