Assignment of the selected product to a sub-group of this object class.

Selection of a reference line in the building to define the mounting height. The selected product determines the reference to the object.

Setting	Reference			Effect
	Upper edge	Centre axis	Lower edge
Ceiling (FCL)				The value at Distance refers to the height of the ceiling (at room height).
Suspended Ceiling (SCL)				The value at Distance refers to the height of the suspended ceiling.
Finished Floor (FFL)				The value at Distance refers to the upper edge of the finished floor level.
Slab (SSL)				The value at Distance refers to the upper edge of the unfinished floor level.
Free				The mounting height is independent of the building model. The value in Distance refers to the height Z=0 in the absolute coordinate system.
User 1 - …User 4 -				The entries User 1 - to User 4 - contain variable standard heights. You can select and modify a standard height (e.g. User 3 - 0.850). To do so, Product is activated for input. The entered value is stored for this entry as new standard height and can also be selected for other objects. This change has no effect on the mounting height of already inserted objects, these are automatically assigned the setting Free.

Depending on the selected product: distance between the selected reference and upper edge, lower edge or center axis of the object.

In the case of settings Free and User 1 - … User 4 - you can enter the mounting height as a number with the desired length unit.

Change-over switch for the operating direction of the value in Distance.

	Installation above the selected reference.
	Installation below the selected reference.

Setting for the behaviour of the object in the event that the height of the selected reference in the building model changes. Example

Setting	Effect
	DDScad calculates a new value for Distance. The object ignores the change of the building model.
	DDScad checks changes in the height ratio between the object and the selected reference using the function Check and Verify Models.Workflow Close all dialogs. Select: Tools Analyze Model Check and Verify Models The dialog appears. Activate the tab: Check Model Activate: changed reference for mounting height Click OK. The test starts. DDScad will report all cases that meet the criteria.

DDScad differentiates the parts list based on the number (= product number). It is set when the item is selected, but can be entered manually if known.

Opens the product database and allows the selection of a product.
