2	Side plate

Picture tab

Use the Picture tab to control the geometry of the connection.

Side plate bolt positions


	Description
1	Define the vertical distance from the lower edge of the purlin to the first bolt in the side plate. By default, this distance is half the purlin height.
2	Define the horizontal distance from the purlin axis to the first bolt in the side plate. By default, the distance is equal to the purlin height.

Gap between purlins


	Description	Default
1	Define the gap between the purlin ends.	`20 mm`

Parts tab

Use the Parts tab to define the part properties.

Parts


Option	Description
Connection plate	Thickness of the connection plate.
Side plate	Thickness of the side plate.
Connection profile	Select the profile from the profile catalog.


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

Flange Blt tab

Use the Flange Blt tab to define the bolt group dimensions and bolt properties.

Bolt group dimensions


	Description
1	Dimension for horizontal bolt group position.
2	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.
3	Bolt edge distance. Edge distance is the distance from the center of a bolt to the edge of the part.
4	Number of bolts.
5	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.
6	Dimension for vertical bolt group position.
7	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.

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

Web bolts tab

Use the Web bolts tab to define the bolt group dimensions and bolt properties.
