Example Example

Before you start

Create one diagonal brace, and one or two horizontal braces. The braces can be built-up beams.

Selection order

  1. Select the first horizontal brace.

  2. Select the diagonal brace.

  3. Select the second horizontal brace (optional).

  4. Click the middle mouse button to create the connection.

Picture tab

Use the Picture tab to define the dimensions that control the position of bolts, and the clearance between the braces.

Dimensions

Description

1

Clearance between the horizontal braces

The ends of the horizontal braces are cut bevel.

2

Bolt edge distance

The end of the diagonal brace is cut according to the bolt edge distance.

3

Bolt spacing

If you do not enter any dimensions, the default values defined in the gauge_lines.dat file are used.

Parameters tab

Use the Parameters tab to define the shape of the brace cut and to create a second bolt.

Brace cut

Option Description

Switch for shape of horiz. braces cut

Select the shape of the cut.

Switch for second common bolt

Select an option to create a second bolt. In addition, check that you have defined the main and secondary bolt gages for the braces on the Picture tab.

The default is No bolt.

By default, this component creates one bolt at the intersection of the main bolt gages of the horizontal brace and the diagonal brace.

Bolts

Click the Bolts button to define the bolt properties.

Bolt basic properties

Option

Description

Default

Bolt size

Bolt diameter.

Available sizes are defined in the bolt assembly catalog.

Bolt standard

Bolt standard to be used inside the component.

Available standards are defined in the bolt assembly catalog.

Tolerance

Gap between the bolt and the hole.

Thread in mat

Defines whether the thread may be within the bolted parts when bolts are used with a shaft.

This has no effect when full-threaded bolts are used.

Yes

Site/Workshop

Location where the bolts should be attached.

Bolt assembly

The selected check boxes define which component objects (bolt, washers, and nuts) are used in the bolt assembly.

If you want to create a hole only, clear all the check boxes.

To modify the bolt assembly in an existing component, select the Effect in modify check box and click Modify.

Slotted holes

You can define slotted, oversized, or tapped holes.

Option

Description

Default

1

Vertical dimension of slotted hole.

0, which results in a round hole.

2

Horizontal dimension of slotted hole, or allowance for oversized holes.

0, which results in a round hole.

Hole type

Slotted creates slotted holes.

Oversized creates oversized holes.

No hole does not create holes.

Tapped creates tapped holes.

Rotate Slots

When the hole type is Slotted, this option rotates the slotted holes.

Slots in

Part(s) in which slotted holes are created. The options depend on the component in question.

Staggering of bolts

Option

Description

Default
