Panels of the Object Settings Dialog Box

Bottom Offset to Home Story: Enter a value to define the object’s base elevation relative to its Home Story.
Bottom Elevation [to Reference level]: Enter a value to define the object’s absolute base elevation, measured to Project Zero or to any other custom-defined Reference Level.
Note: The Bottom Elevation shows the current elevation of the Object bottom. Thus, this value serves as a calculation tool only, not a link. If you change the position of a Reference level, the Object will not change its position.
Dimensions 1 and 2: enter the two orthogonal size values (e.g. length and width) of the object.
Height: Enter the object’s height.
Relative to Orientation (the angle will be measured relative to the Oriented View);
Absolute to Coordinate System (the angle will be measured from the (0,0) point of the project coordinates).
Check the Mirror Library Part box to mirror the chosen Library Part when placing it, or to mirror a selected object. (View the preview after checking this box to see how the object will be placed.)
The Preview Area at the right shows you the object in different displays, depending on which of the icons (at left) that you choose. As you set different parameters for the object, keep an eye on this preview to see the effects of your edits.
Move the cursor inside the Preview Area and the cursor will change to a “flip” arrow, allowing you (in the Plan or 3D previews) to alternately view each side of your Library Part.
Note: To modify the predefined preview picture, use the Preview Picture controls in the GDL Object Editor.
Move the cursor inside the Preview Area and the cursor will change to a “rotate” arrow, allowing you (with successive clicks) to rotate the Plan or 3D preview.
Click the Info button to see further information about the library part (e.g. author, description). If you share your own library part to the BIM Components Portal, you have the opportunity to enter this information during the process.
Home Story: Choose a Home Story for the Object: by default, it is the Current Story, but you can click Select Story instead and choose any other Story as the Home Story.
The Minimal Space parameter (included with many Objects from the default ARCHICAD Library) defines the area surrounding the placed object that you want to keep free. You can opt to display the minimal space of all objects in 2D views, depending on the global options set at Model View Options.
Show on Stories: Use this pop-up (where available) to control the stories on which objects will be displayed: on its Home Story only, or in outline form on other stories as well.
For these settings to take effect, make sure that the applicable Override Object’s /Line Types/Pens/Attributes checkbox(es) are on.
Note: For some objects, no GDL Object parameter is defined. In this case, the object will be displayed using the attributes defined in the Floor Plan and Section panel (regardless of the Override checkboxes).
Custom Texture Alignment:If this message is activated, it means that the currently selected object (already placed in the project) has been assigned a custom 3D texture.
In this case, the Reset Texture button is also activated. Click to restore the origin of the Texture of the selected object.
