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.

Stiffener creation


Option	Description
	Select whether bevel, square, or no flange stiffeners are created. Bevel is the default. AutoDefaults can change this option.
	Select how many web stiffeners are created, or whether they are created at all. Two stiffeners is the default. AutoDefaults can change this option.
	Select whether bevel, square, or no inner stiffeners are created. Bevel is the default. AutoDefaults can change this option.

Stiffener creation

Select how many stiffeners are created, define the shape of the stiffeners, and the chamfer dimensions.


	Description
1	Define the external stiffeners.
2	Define the inner stiffeners in the corner between the main and the secondary part.

Chamfer dimensions


	Description
1	Horizontal chamfer dimension
2	Vertical chamfer dimension

Chamfer shape


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

Bolts tab

Use the Bolts tab to define the bolt properties, number of bolts, and spacing. You can select whether outer and inner bolts are created.

Bolt group dimensions


	Description
1	Bolt edge distance. Edge distance is the distance from the center of a bolt to the edge of the part.
2	Number of bolts.
3	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.

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 checkbox 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.
