Trim (3-D SE)

Steel Engineering > Trim

You use the functions of the Trim menu to cut beams on a section object. The trim can be made with or without the beam being lengthened. Furthermore, you can specify a clearance between section object and beam.

Basic procedure:

Identify the beam end to be trimmed

Activate or deactivate the With lengthening checkbox, depending on your requirements. If the checkbox is inactive, only the piece of the beam that intersects the identified section object is trimmed.

Specify the value for the clearance.

Identify the section object.

Trim to edge

Cutting a beam to a 3-D edge. You can also use 2 points to define the edge.

Example

Trim beam, to outer beam edge

Cutting a beam to the outer edge of another beam. The beam to be cut must be identified on the section side.

It particularly makes sense to use these functions to trim round beams, pipes etc. and when working with the new design variants.

Example

Trim beam, to surface

Cutting a beam to a surface. The following options are available for defining the cut surface:

2 edges

Identification of two edges. The first edge represents the x-axis and the second the y-axis.
Edge-Point

Identification of an edge as the x-axis near the local origin and specification of a point on the y-axis.
3 points

Specification of three points. The first point is the origin of the new coordinate system, while the second and third points are points on the x-axis or y-axis.
Surface

Specification of a surface through identification of two edges.
Perpendicular to edge

Specification of a surface through identification of an edge. The surface is then generated perpendicular to this edge.

Trim with lengthening changes the beam length and the trim angle at the identified beam end!

Example

Mitre cut

This function mitre-cuts two beams. The cut can be made flush or with a clearance.

If you enter 0 in the Clearance input field, the beams are mitre-cut flush, i.e. without clearance between the cut surfaces.

If the specified value is greater than 0, a defined gap, a so-called clearance, is created between the cut surfaces. Each of the flush-cut beams is shortened by half of the respective gap width.

Example

Trim beam, to part

Cutting a beam to a pipe. Note that the trim can only be performed if there is a genuine section surface for the parts

Trim with Lengthening adapts the beam to be trimmed to the pipe. Trim without Lengthening only trims the part of the beam that abuts the part/intersects it.

Example

Trim beam, to 2-D line

Cutting a beam to a 2-D line. The cut plane is projected perpendicular to the screen plane. You can also define the 2-D cutting line by specifying two points.

Example

Please note:

If you call the functions ...to edge, ...to 2-D line or ...to surface via the context menu (RMB) to trim a selection of several beams, you are enabled to determine the beam end definition:

Selected side
The identification point determines the side of the intersecting plane to which the end is to be trimmed in case of intersecting beams.

Selected end
The identification point determines the beam end.

When you trim beams, only the intersecting plane will be entered in the feature log, but not the selected points/edges for plane definition. An exception is the plane definition via 2 edges; here, the selected edges will also be included in the feature log.

	Trim to edge Cutting a beam to a 3-D edge. You can also use 2 points to define the edge. Example Trimming to an edge Left: Original, Centre: Without lengthening, Right: With shortening
	Trim beam, to outer beam edge Cutting a beam to the outer edge of another beam. The beam to be cut must be identified on the section side. It particularly makes sense to use these functions to trim round beams, pipes etc. and when working with the new design variants. Example Beam (1) Trim to beam outer edge (2), Bottom left: Without lengthening, Right: With lengthening
	Trim beam, to surface Cutting a beam to a surface. The following options are available for defining the cut surface: 2 edges Identification of two edges. The first edge represents the x-axis and the second the y-axis. Edge-Point Identification of an edge as the x-axis near the local origin and specification of a point on the y-axis. 3 points Specification of three points. The first point is the origin of the new coordinate system, while the second and third points are points on the x-axis or y-axis. Surface Specification of a surface through identification of two edges. Perpendicular to edge Specification of a surface through identification of an edge. The surface is then generated perpendicular to this edge. Trim with lengthening changes the beam length and the trim angle at the identified beam end! Example Trim to surface, with lengthening
	Mitre cut This function mitre-cuts two beams. The cut can be made flush or with a clearance. If you enter 0 in the Clearance input field, the beams are mitre-cut flush, i.e. without clearance between the cut surfaces. If the specified value is greater than 0, a defined gap, a so-called clearance, is created between the cut surfaces. Each of the flush-cut beams is shortened by half of the respective gap width. Example Top: Source beams, Bottom: Mitre-cut with clearance (left) and flush (right)
	Trim beam, to part Cutting a beam to a pipe. Note that the trim can only be performed if there is a genuine section surface for the parts Trim with Lengthening adapts the beam to be trimmed to the pipe. Trim without Lengthening only trims the part of the beam that abuts the part/intersects it. Example Trimming a pipe (1) to a different pipe (2) with lengthening
	Trim beam, to 2-D line Cutting a beam to a 2-D line. The cut plane is projected perpendicular to the screen plane. You can also define the 2-D cutting line by specifying two points. Example Beam (1) Trim to beam outer edge (2), Bottom left: Without lengthening, Right: With lengthening
