Creating walls from spaces

For flexibility in the design process, walls can be created automatically based on existing objects in the drawing including spaces, polygons and shapes. Because of the special relationship between walls and spaces, a dedicated command creates walls from spaces. To create walls from other objects, see Creating objects from shapes.

Once the floor plan has been developed with multiple spaces, the interior and exterior walls can be automatically created.

1. Ensure that space objects are present in the drawing. To automatically create walls with a 3D height, specify a delta-Z value for the design layer where the walls will be created.

The Create Walls from Spaces dialog box opens. Specify the style of walls to create and their location.

Parameter	Description
Create Walls from Selected Spaces Only	Creates walls from selected spaces; deselect to create walls from all the spaces in the source layer
Source Layer	Specifies the layer containing the space objects
Destination Layer	Indicates the layer on which to create the walls
Place Exterior Walls	Select how to align the exterior walls with the spaces
Align Outer Side to Space Edge	Creates the exterior walls along the inside of the space polylines; select this option if the spaces represent the gross area
Align Inner Side to Space Edge	Creates the exterior walls along the outsides of the space polylines; select this option if the spaces represent the net area
Align Centerline to Space Edge	Creates the exterior walls centered along the outside edges of the space polylines
Align Wall Control Offset to Space Edge	Creates exterior walls that are offset as determined by the Exterior Wall Style
Place Relative To	Determines whether the wall’s alignment with the space edges is relative to the whole wall or to the wall’s core component. If the selected wall style has no defined core component, alignment is always relative to the wall.
Exterior/Interior Wall Style	Select a wall style for the exterior and interior walls from a library or the current file
Constrain straight walls to vertical or horizontal	Creates straight vertical or horizontal walls out of spaces that are not perfectly vertical or horizontal
If they are within ___ degrees of vert/hor	Indicates the threshold for constraining walls; walls that deviate from vertical or horizontal within the number of degrees specified are automatically straightened
Combine collinear interior walls	Draws multiple, collinear interior walls as a single wall

The available wall styles are defined by wall style resources (see Using wall styles).

Exterior and interior walls are applied automatically to the spaces. Round walls approximating the curves are used for Bézier and cubic spline vertices in the space objects.
