Parts


Part	Description
Plate	Thickness, width and height of the end plate.
Sec plate	Thickness, width and height of the secondary end plate.
Haunch prof	Select the haunch profile from the profile catalog.

Beam stiffener	Thickness, width and height of the column stiffener.


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.
Finish	Describes how the part surface has been treated.

Parameters tab

Use the Parameters tab to define the plate positions and dimensions.

Plate positions and dimensions


	Description
1	Gap between the end plates. You can define the gap either as a distance or as an angle.
2	Select whether the gap is defined as a distance or as an angle (degrees). By default, the gap is created as a distance.
3	Haunch plate height
4	Gap between the stiffeners and beam flanges
5	Stiffener edge distance to the haunch edge
6	Haunch plate length
7	Haunch plate chamfer size

Parallel haunch end cuts

If you have selected the haunch profile from the profile catalog, you can select that the haunch ends are cut parallel.

Chamfer dimensions



1	Horizontal chamfer dimension
2	Vertical chamfer dimension

Chamfer type


Option	Description
	Default Line chamfer AutoDefaults can change this option.
	No chamfer
	Line chamfer
	Convex arc chamfer
	Concave arc chamfer

Bolts tab

Use the Bolts tab to define the bolt group dimensions and bolt properties.

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	Dimension for vertical bolt group position.
4	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.
5	Dimension for horizontal bolt group position.
6	Select how to measure the dimensions for horizontal bolt group position. Left: From the left edge of the secondary part to the leftmost bolt. Middle: From the center line of the secondary part to the center line of the bolts. Right: From the right edge of the secondary part to the rightmost bolt.

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 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.

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.

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

Chamfers tab

Use the Chamfers tab to define the chamfer types and dimensions for the haunch plate chamfers.

Chamfers

You can define each chamfer separately.

Holes tab

Use the Holes tab to define the holes created in the end plates.

Hole dimensions

You can define the holes separately for the main part end plate and the secondary part end plate. The main part end plate values are used as default values for the secondary part end plate.


Option	Description
	Define the hole group dimensions in the rafter.
	Define the hole group dimensions in the haunch.


Option	Description
Bolt standard	Select the bolt standard.
Bolt type	Select the bolt type to define the location where the bolts should be attached.
Read data from	You can select to use the sinkholes.dat definition file to specify the default values for horizontal and vertical offsets, and the diameters for upper and lower holes. The file is searched in the following order: Environment common system steel folder (..\Environments\common\system\Steel), model folder, `XS_FIRM`, `XS_PROJECT` and `XS_SYSTEM` folder. You can also select to define the holes in the component dialog box.
