Remarks

This function is used to delete an attribute, defined by the typeID and index field of the attribute header. Certain attributes in the database can not be deleted; see the return values.

Note, that deleting an attribute do not effect any changes in the element database; they will refer to an attribute which is missing. That is not a problem, the server applications work in the same way when an attribute is deleted from the menus. The only exception is the layer attribute. Once a layer is deleted all the elements will be deleted; no matter in which database they are. The floor plan and all the section/elevations will be scanned to delete the elements which are on the given layer.

  You can delete more than one attribute of the same type with the ACAPI_Attribute_DeleteMore function.

This function is a non-undoable data structure modifier function. See more details on this topic at Command Overview.

 

Example

API_Attribute attrib = {};
attrib.header.typeID = API_LinetypeID;
attrib.header.index = 5;

GSErrCode err = ACAPI_Attribute_Delete (attrib.header);

 

Requirements
