Situation	Description
	Two custom anchors.
	Bolt anchors that are custom parts, hangup bars and crane cables.
	Cast-in lifting anchors that are custom parts.
	Cast-in wire rope lifting hoops that are custom parts. Adjusting anchors are in the front side. The component is applied two times.

	Part
1	Concrete part (wall, column, beam, slab)
2	Point You can select multiple points.

Input tab

Use the Input tab to control the custom parts used for the embeds, the input points for placing the embeds and the component direction properties.

Input point sequence

Select the distribution method for the embeds. You can also adjust the placement of embeds on the Input tab.


Option	Description
	Select a concrete part and pick one position point for the anchor.
	Select a concrete part and pick multiple position points for the anchors.
	Select a concrete part and pick three points to define the plane. Pick a point to place the embed.
	Select a concrete part and pick three points to define the plane. Pick multiple points to place the embeds.

Up direction

Define how the embeds are rotated.

This option is not available if the three-point-plane option is selected from the Input points sequence list.

The coordination system determines the position of anchors. You can use the global directions (whole model) +X,-X,+Y,-Y,+Z,-Z or the local directions (part) +X,-X,+Y,-Y,+Z,-Z to define a specific face of a typical cube-shaped (slab, wall, beam, or column) part.

The anchor placement is illustrated with yellow rectangles, as shown in the example image below. You can change the positions by selecting another option from the list.

Note that with the Top in form face option, the anchors are always placed on the face that is selected as the top-in-form face of the cast unit.


-X local:
+X global:
Top in form face:

Embed handling

Anchor type

Select the type of the anchors from the Anchor type dropdown list. The options are:

Anchor created by top part and bottom part
Component part

Surface treatment
Component part and component detail
Component part and top and bottom part
Component detail and top and bottom part

Custom part


Option	Description
Partname component	Select a custom part from the Applications & components catalog to be used as an embed. Select a configuration file. Select whether the custom parts must be used for the embeds. The custom part can be connected to the main part as welded, added material, add to cast unit, or add as sub-assembly. Select how the embeds are rotated. The default direction is 2 point +x. Select how the embeds are rotated around a position point. If needed, set Check top-in-form face direction to Yes to check the top-in-form face of the cast unit and to adapt the direction of the custom part. If the input start and end points of the cast unit are reversed, the custom part rotation remains the same based on the top-in-form face.
Keep local direction	Use the Keep local direction setting to ensure that all anchors placed on opposite faces have the same Y axis always pointing to the main part of the assembly. This setting cannot be used together with the Check top-in-form-face direction setting.
Detailname component	Select a custom detail from the Applications & components catalog to be used as embed. Select the configuration file.
Surface treatment	Define the thickness, width, and height of the surface treatment. Enter the name, color, and subtype.

Preference type list	Define the prefered order of anchor types. Start with the highest preference group and separate the groups with a space.
If more anchors available	Several fabricators have lifting anchors with the same lifting capacity, but with different anchor lengths. Use the order in the configuration file to define which anchor is selected. First found anchor with the correct capacity = 1, second found anchor = 2, and so on.
Exclude vertical cables in calculation	Select whether vertical crane cables are taken into account in the anchor calculation.
