Lengthen edge, to point

Sketch > Process > Trim > Lengthen edge, to point

Edges are lengthened or shortened to a specified point.

Identify the edge near the end to be lengthened/shortened. Specify the new position of this end point. The point does not need to lie on the graphical element or its extension.

Lengthened or shortened will always be the side of the edge which is closest to the identification point of the edge. if the lengthening point is located within the edge or a circular arc, the element will be shortened. "Within" here means that the lengthening point lies between the "imaginary" straight lines which run perpendicular to the edge through both end points. The same applies to circular arcs.

Example

Lengthen edge, to edge

Sketch > Process > Trim > Lengthen edge, to edge

Graphical elements - lines or arcs - are lengthened or shortened to another edge.

1. Identify the edge near the end to be lengthened/shortened.
2. Identify the edge to which you want to lengthen/shorten.

When you trim a line to a circle or an arc, the selected line section will be lengthened or shortened to the intersection point with the circle/arc that is nearest to the identification point (for the circle/arc).

Examples

Trim 3-D c-edge, in screen plane

Sketch > Process > Trim > Trim 3-D edge, in screen plane

Use this function to trim the section of a graphical element to the nearest intersection point with another graphical element. The graphical elements are projected onto the screen plane. There, the intersection points are determined. These are projected back onto the original edge and the section is removed. In the case of circles and ellipses which are projected onto one line, several sections may be removed.

Example (3-D sketch)

Trim 3-D c-edge, in processing plane

Sketch > Process > Trim > Trim 3-D edge, in processing plane

This function deletes the section of a graphical element up to the nearest intersection point with another graphical element. Here, the graphical elements are however first projected in the active processing plane, where the intersection points are determined. These are projected back onto the original edge and the section is removed. In the case of circles and ellipses which are projected onto one line, several segments may be removed.

Lengthen, by value

Sketch > Process > Trim > Lengthen, by value

Graphical elements - lines or arcs - are lengthened/shortened by a specified value.

1. Identify the edge to be lengthened/shortened.
2. Enter the value for the length change. If you enter a negative value the graphical element will be shortened.

Lengthen/Shorten edge, to surface

Sketch > Process > Trim > Lengthen/Shorten edge, to surface

Graphical elements - lines or arcs - are lengthened/shortened to specified surface.

1. Identify the edge to be lengthened/shortened.
2. Identify the surface to which you want to lengthen/shorten.

Close corner...

Sketch > Process > Trim > Close corner...

This functions connects 2 graphical elements. The elements will either be lengthened or shortened in the process.

	Close corner, via inner corner This function connects two graphical elements by specification of the inner corner. Specify the inner corner. HiCAD automatically attempts to connect the graphical elements which are nearest to this point. Example
	Close corner, via 2 GE Use this function to connect 2 graphical elements.  Identify the two graphical elements. Identify the inner corner.
