Chamfer Edges and Facets (3-D)

3-D Standard > Process > Chamfer

To chamfer edges/facets, first activate the Edges, Facets option field in the Chamfer dialogue window.

The appropriate creation ad selection options are then available to the user.

Creation Types

In addition to the normal, exact chamfering, the creation types Rolling Ball and Standard are available to the user.

The Rolling Ball option is used if you want to create tapered chamfers; these cannot be generated with the creation type Exact .

If you select the creation type Standard, HiCAD will first try to create the chamfer using the Exact option. If this does not work, the Rolling Ball option will be executed instead.

Example:

A chamfer is to be applied to the edge marked pink on the left:

Options: Tangential c-edge, Entry mode: Length, Chamfer length: 10

Input Types

Depending on which input type you choose, different value inputs will then be required.

Length

Specifying the chamfer length chamfers the edges/facets at an angle of 45°.

Enter the chamfer length and identify the edges to be chamfered. The last selected edge/facet is highlighted in blue, all other selected edges/facets being highlighted in green.

This input type performs a symmetrical chamfer, i.e. the distance between the chamfer cross-section and the chamfer edges is the same on both sides.

Left: Original part with selected edge; Right: Chamfered edge, input type: Length

2 Lengths

The edges/facets are chamfered by specifying two chamfer lengths. This also makes asymmetrical chamfers possible if different chamfer lengths are used. With asymmetrical chamfering, the distance between the chamfer cross-section and the chamfer edges is different on both sides.

Left: Selected surface; Centre: Chamfered surface, input type: 2 Lengths, symmetrical; Right: Asymmetrical

Left: Selected edge, Centre: Chamfered edge, input type: 2 Lengths, symmetrical, Right: Asymmetrical

Length + angle

The edges are chamfered by specifying the chamfer length and the chamfer angle. Enter the values you want. You can use the Swap Surface for Angle checkbox to influence the side of the selected edge on which the chamfer length is marked off .

Left: Selected edge, Centre: Chamfered edge, input type: Length and Angle, Swap Angle no, Right: Swap Angle yes.

In addition, you can also define that, when chamfering edges/facets, all tangentially adjoining edges are automatically chamfered. To do this, activate the Tangential c-edge checkbox.
