Crosshairs (3-D)

3-D Standard > Tools > Crosshairs

The Crosshairs menu provides functions for the creation and deletion of crosshairs and surface axes for various 3-D elements.

Crosshairs		Example
	Crosshairs, Bore/C-edge Creates the crosshairs by Specification of a boundary edge Specification of a start point of the crosshairs (for the size)
	Clicking opens a menu with the following functions:
	Crosshairs, Slot Creates the crosshairs by specification of two edges of the slot.
	Crosshairs, Rectangle Creates the crosshairs by identification of two edges of the rectangle.
	Crosshairs, Hole pattern Creates the crosshairs by Specification of the centre point of the hole pattern Identification of two adjacent bore circles
	Crosshairs, Sphere/Torus Creates the crosshairs by identification of a circle/circular arc of the sphere/torus specification of the start point of the crosshairs if required, specification of another point of the crosshairs (sphere)
Axis, individual		Example
	Axis, Cylinder surface Creates an axis by identification of a surface via two edges.
	Axis, Via 2 points Creates an axis by specification of two points.
Delete axes/crosshairs
	Individual Deletes individual axes. Identify the desired axes.
	Group Deletes a crosshairs group. Identify one of the axes. If, for example, you have identified one axis of the crosshairs of a sphere, all axes are deleted.
	All in active part Deletes all axes/crosshairs of the active part.

The Axis,Cylinder surface function creates the surface axis for a cylinder surface or for the polyhedral facet of a of a polyhedrised 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).
