Plate creation

Option Description

Select whether one or two connection plates are created between the brace web and the gusset plate.

Select whether a filler plate is created between the connection plate and the brace web.

The default is that a filler plate is not created.

Clip angle creation

Define whether the braces are attached to the gusset plate using clip angles or shear tabs, and specify the number of clip angles to create. The default option is to create two clip angles below the brace web.

Clip angle orientation

Define how the clip angle is placed on the connection.

Option Description

Default

Clip angle is placed on the connection so that the longer leg is connected to the gusset plate.

AutoDefaults can change this option.

Clip angle is placed on the connection so that the longer leg is connected to the main part.

Connection type

Option Description

Select the connection type (weld or bolts) between the gusset plate and the connection plate.

Select the connection type (weld or bolt) between the gusset plate and the L profile.

Shim plates tab

Use the Shim plates tab to define shim plate properties.

Plates

Option Description

Shim plate 1, Shim plate 2, Shim plate 3

Thickness, width and height of the shim plates.

Option

Description

Default

Pos_No

Prefix and start number for the part position number.

Some components have a second row of fields where you can enter the assembly position number.

The default part start number is defined in the Components settings in File menu > Settings > Options.

Material

Material grade.

The default material is defined in the Part material box in the Components settings in File menu > Settings > Options.

Name

Name that is shown in drawings and reports.

Shim plate position and number

You can create shim plates when connecting braces to the gusset plate using clip angles.

De

1

Define the gap between the brace and connection plate.

2

Define how many shim plates are created at the top and bottom flanges.

Enter the shim plate profile numbers: 1, 2 or 3. These are the numbers that are on the upper part on the Shim plates tab.

For example, if you want to create three shim plates at the top flange, and you want to use Shim plate 1 twice and Shim plate 2 once, enter 1 1 2. The first number you enter is the shim plate closest to the brace flange.

Brace bolts tab

Use the Brace bolts tab to control the bolts that connect the braces to the gusset plate.

Bolt group dimensions

Description

1

Number of bolts.

2

Bolt spacing.

Use a space to separate bolt spacing values. Enter a value for each space between bolts. For example, if there are 3 bolts, enter 2 values.

3

Bolt edge distance.

Edge distance is the distance from the center of a bolt to the edge of the part.

4

Dimension for vertical bolt group position.

5

Select how to measure the dimensions for vertical bolt group position.

  • Top: From the upper edge of the secondary part to the uppermost bolt.

  • Middle: From the center line of the bolts to the center line of the secondary part.

  • Below: From the lower edge of the secondary part to the lowest bolt.

6

Select the bolt type.

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

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

Not staggered

AutoDefaults can change this option.

Not staggered

Staggered type 1

Staggered type 2

Staggered type 3

Staggered type 4

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.

Bolt length increase

Define how much the bolt length is increased. Use this option when, for example, painting requires the bolt length to be increased.

Angle bolts tab

Use the Angle bolts tab to control the bolts that connect the clip angles.

Bolt group dimensions
