Lengthen/Shorten Edges (Sketch)

Lengthen line, by value

Sketch > Process > Trim > Lengthen line, by value

Use this function to lengthen or shorten lines (straight lines or arcs) by a particular value or to a new total length.

When you call the function, the following dialogue window will be displayed:

When you move the cursor over the lines of a sketch while the dialogue window is open, a dynamic preview of the lengthening or shortening will be displayed.

Click the highlighted line to process it.

In the Previous total length field shows the current length of this line. Specify the desired new length and the type of lengthening or shortening by activating the Change by or New total length option and enter the desired value.

To perform the lengthening or shortening as shown in the image above,click Apply or OK.

OK

Lengthens/shortens the highlighted line as shown in the preview, and closes the dialogue window.

Cancel

Discards the value inputs and closes the dialogue window.

Apply

Lengthens/shortens the highlighted line as shown in the preview. The dialogue window remains open, enabling you to change the length of further lines.

 

This function also takes HCM constraints into account.


Lengthen line, to surface/line/point

Sketch > Process > Trim > Lengthen line, to surface/line/point

Use this function to lengthen or shorten sketch lines to a surface, a line or a point.

Select the line you want to lengthen or shorten. Then, you can dynamically lengthen or shorten the line by moving the cursor. In the process, the lengthened/shortened line will be highlighted in a different colour. The lengthening/shortening will be applied as son as you select a point or an edge.

When you select an edge, the intersection point of the edge projected onto the sketch plane with the selected line will be detected, and the line will be lengthened or shortened up to this point. For 3-D sketches, "real" intersections of edges are required.

If a lengthening or shortening is not possible, a corresponding message will be displayed:

Selection leads to incalculable result.

Line length adjustment failed.

 

Instead of selecting a point or an edge you can right-click to activate a context menu with further options:

Select surface

This function enables you to lengthen/shorten the selected line up to a surface. Select the desired surface.

Step back

Select this function to undo one or several of the last steps.

Cancel (ESC)

Cancels the function.

 

Please note:

 

Example 1 - Lengthen to point

(1) Selected line, (2) Point selected with cursor, (3) Lengthened line

 

Example 2 - Shorten to edge

(1) Selected line, (2) Selected edge (Projection 2a will be used), (3) Shortened line, (4) Coincidence constraint between point and edge
