Comment	Add a comment about the part.

Parameters tab

Use the Parameters tab to define the stiffener chamfers and dimensions.

Chamfer shape


Option	Description
	Default Line chamfer AutoDefaults can change this option.
	No chamfer This shape may cause a clash between the stiffener and I profile rounding.
	Line chamfer
	Convex chamfer
	Concave chamfer

Chamfer dimensions


Main part stiffener	Secondary part stiffener


	Description
1	Horizontal chamfer dimension for the main part stiffener and the secondary part stiffener
2	Vertical chamfer dimension for the main part stiffener and the secondary part stiffener

Bolts tab

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

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 horizontal bolt group position.
4	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.
5	Dimension for vertical bolt group position.
6	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.
7	To modify the bolt assembly, select the Effect in modify check box and click Modify.

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.

Rods tab

Use the Rods tab to define the rod, nut, and washer properties and dimensions.

Parts


Option	Description
Rod profile	Select the profile from the profile catalog.
Nut profile	Select the profile from the profile catalog.
Nut 2 profile	Select the profile from the profile catalog.
Washer 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.
