Chamfer Sketch (Sketch)

Sketch > Process > Chamfer

Use this function to chamfer corners of polylines. If desired, you can automatically assign HCM constraints in the process.

When you call the function, the Chamfer dialogue window will be displayed.

 

Chamfer, 1 length

Chamfers corners by specifying one chamfer length.

Input field: Length

Chamfer, 2 lengths

Chamfers corners by specifying two chamfer lengths.

Input fields: Length 1 and Length 2

The first chamfer length applies to the edge closest to the identification point.

Chamfer, Angle and Length

Chamfers corners by specifying the chamfer length and the chamfer angle. 

Input fields: Length and Angle

 

Create dimensional constraints

If this checkbox is active, a HCM constraint will be automatically created for the filleted corners. The checkbox will be greyed out if the Sketch - Enter constraints checkbox in the Settings dialogue (Sketch > HCM > Tools > Settings) has not been activated.

 

Equate dimensional constraints

This checkbox can only be used if the Create dimensional constraints checkbox has been activated. If this is the case, the dimensional constraints will be equated for all corners that have been chamfered in one step. This means that the first chamfered corner contains the constraints, and the other chamfered corners contain a "reference" to this constraint. If one of these chamfers is modified afterwards by a subsequent changing of the dimensional constraint, the other chamfers will be adjusted automatically.

The equation of dimensional constraints in only possible for distance constraints in planar sketches. The setting will be ignored for 3-D sketches.

 

Retain corners with HCM constraints

This option is relevant if a HCM constraint has already been assigned to the corner you want to chamfer. If you want to retain the corner as a part of this constraint even after chamfering, activate this checkbox. Otherwise, the constraint will be removed.

Specify the required settings and select the desired edges in the vicinity of the corner to be chamfered. If you move the cursor over an edge, it will be highlighted in colour (Magenta, special colour Marking 1) and a preview of the chamfer is displayed. When you click on the edge, HiCAD will searches for the next corner and highlights the corresponding edges (Red, special colour Marking 5). If an already selected edge is selected again, it will be removed from the selection, and its highlighting will also be removed.

If you right-click during the selection process, a context menu with further options will be displayed:

  • Move the cursor to the position of the first corner point of the rectangle.
  • Hold down the CTRL key and the left mouse button.
  • Release the CTRL key and draw, while still holding down the left mouse button, the rectangle.
  • When you then release the left mouse button, all lines/edges within the rectangle will be selected.

 

If you click Apply, the selected chamfers will be applied, while the window remains open, allowing you to chamfer further edges (even with different settings if desired). If you click OK, the selected chamfers will also be applied, but the dialogue window will be closed.

If you middle-click in the drawing while the dialogue window is displayed, the following will happen:

 

The images below show two examples:

Example 1

In Sketch (1) two highlighted edges (2) are selected: Without dimensional constraints equation (3), and with dimensional constraints equation (4).

 

Example 2

Here a corner (1) is chamfered that is already part of a distance constraint: With retaining of constraints (2) and without retaining (3).
