Parts

Option Description Default

Column plate

Thickness and height of the column plate

Thickness = 10 mm

Height = main part height - main part flange thickness mm

Connection plate

Thickness, width, and height of the connection plate

Thickness = 10 mm

Width is calculated by the bolt positions.

Height is equal to the main part height.

Triangular plate

Thickness of the triangular plate

10 mm

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.

Bolts tab

Use the Bolts 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
