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:

  1. Identify the beam end to be trimmed
  2. 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.
  3. Specify the value for the clearance.
  4. Identify the section object.

 

Trim to edge

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

Trim beam, to outer beam edge

Trims 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.

Trim beam, to surface

Trims 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!

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.

Trim beam, to part

Trims a beam to a different Steel Engineering part, e.g. 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 trimmed beam to the part. Trim without Lengthening only trims the part of the beam that abuts the part/intersects it.

Trim beam, to 2-D line

Trims 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.

Beam length / Trimmed length

When beams are trimmed, the value assigned to the part attribute Length will be the total length of the trimmed beam. If two trimmings are applied to a beam, the calculated length will be the smaller of the two individual total lengths after applying the trimming. The beam length and the trimmed length will then be identical.

(1) Line for 1st trimming; (2) Line for 2nd trimming

 

An exception are cases where one of the trimmings is performed at a 90° angle. In such cases, the length resulting from the 90° trimming will not be considered for the calculation of the minimum (the reason for this are processing steps with a saw). Use the part attribute

Trimmed length (§24)

for a correct calculation of the trimmed length. This attribute can, for instance, be used for annotations, in part attribute masks or in BOMs.
