Situation	Description
	Brace profile: RHS, W RHS brace is bolted to the gusset plate using a tongue plate. W profile braces are bolted directly to the gusset plate.

Before you start

Create a gusset plate, and 1 to 10 braces.

Selection order

Select the main part (gusset plate).
Select the secondary part (first brace).
Select the second secondary part (second brace).
Select the subsequent secondary parts (subsequent braces).
Click the middle mouse button to create the connection.

	Brace is welded.
	Brace is bolted.
	Brace is welded and notched around the nuts.
	Tongue plate and cover plate are created.

Cut in bracing

If needed, you can create a cut in the bracing.

Define the width of the cut in the bracing, where t is the thickness of the connection plate.

Define the length of the cut in the bracing from the edge of the connection plate.

Gusset and connection plate distance

Define the distance between the gusset plate and the connection plate.

Round cut in bracing

If needed, you can create a round cut in the bracing. Enter the radius value.

Note: The following examples show only some of the available options. You will find more options on the Brace conn tab.

Connection plate

Define whether the brace is notched or the connection plate cut when the connection plate is connected to the brace.


Option	Description
	Default Brace is notched. AutoDefaults can change this option.
	Connection plate is cut.
	Connection plate is cut, but the part of the connection plate created inside the bracing is not deleted.
	If you cut the connection plate, you can define the size of the gap between the brace and the connection plate.

Number of connection plates

Define whether one or two connection plates are used for connecting the brace to the gusset plate.


Option	Description
	Default One connection plate. AutoDefaults can change this option.
	Two connection plates and a middle end plate at the ends of the connection plates.
	If a middle end plate is created, you can define the width of the end plate.
	Select the middle end plate position.

Connection plate chamfer

Define whether the connection plate is chamfered.


Option	Description
	Default No chamfers are created. AutoDefaults can change this option.
	Chamfers are created.
	If you create chamfers, define the vertical and horizontal chamfer dimensions.

End plates

If you use the end plates to seal the braces, define the end plate shape and dimensions.


Option	Description
	Default Square end plate. AutoDefaults can change this option.
	Round end plate.
	End plate edge distance from the brace outer edge.

End plate chamfer

Define the end plate chamfer type and horizontal and vertical dimensions.

Brace bolts 1 tab

Use the Brace bolts 1 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	Select how to measure the dimensions for vertical bolt group position.
5	Dimension for vertical bolt group position.

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.	`Site`

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 or tapped holes. No hole does not create 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.

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.
