Using additional components

You can use additional system or custom components to modify the column end or the base plate. For example, you can create special backing plates, weld preparations, and weld access holes for the column end.

If you use additional system or custom components, you need to manage the column end or the base plate properties in the additional component in question. When using several components, there may be multiple welds and cuts.

Option

Description

Component

Select a system or a custom component from the Applications & components catalog.

Attributes

Select an attribute file for the component.

Input

Define to which parts the selected component is applied.

  • Default is same as Base + Column.

  • Column sets the column as the main part. Use this option for details.

  • Column + Base sets the column as the main part and the base plate as the secondary part.

  • Base + Column sets the base plate as the main part and the column as the secondary part.

  • Base sets the base plate as the main part.

Bolts tab

Use the Bolts tab to control the bolt properties.

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.

Anchor rods tab

Use the Anchor rods tab to control the creation of different types of anchor rods.

Grouting helps you to model columns to the top of concrete parts and place the base plate correctly. It also makes it easier to dimension the detail in GA drawings.

By default, no grouting is created.

Select whether the grouting is created with or without slopes above or below the detail creation point. This also affects the shim plates.
