Using the Magic Wand to Automatically Trace Elements

By Jon Sage, December 4, 2003

The Magic Wand Tool is very versatile for automatically tracing elements with ArchiCAD. This tutorial will look at several different applications of the Magic Wand Tool.

EXAMPLE 1
In our first example, we will trace a simple polyline element. First draw a sequence of polylines and close the polygon.

Select the Wall Tool and choose the parameters for the wall height, width, material, etc., and then Magic Wand the polylines.

Instantly, the walls will be traced around the set of polylines. This also works on individual lines, or from a DWG template file.

Repeat this process with the Slab tool as well.

In this next example, we will create a barrel vault roof and control the resolution of the curvature.

First, draw an arc representing the profile of the roof, as shown in the image below:
