Magic Wand

The Magic Wand (shortcut: Spacebar) saves you work by finding and tracing a linear or polygon shape from among existing elements, and then generating a new element based on the polygon.

If you click on an edge or node, the Magic Wand traces the element and/or element chain.

If you click in empty space, or on a surface, the Magic Wand traces the closed geometric area formed by the nearest elements.

How to Create an Element with the Magic Wand

1.From the Toolbox, select the type of the new element you want to create.

2.Activate the Magic Wand by doing one of the following:

Press the Spacebar

Click the Magic Wand icon in the Control Box

Choose Design > Outline Polygon with Magic Wand

3.View the graphical feedback to see the potential result(s). (See below).

4.Click to automatically find and trace a polygon shape.

Graphical Feedback

While the spacebar is pressed, move the cursor around to view feedback on the possible resulting elements. Here, if you are using the Magic Wand to create Walls atop two intersecting slabs, the feedback shows you the possibilities:

Note: The Magic Wand preview highlight color can be set in the Work Environment settings.

See Selection and Element Information.

Magic Wand Cursor Icons

The Magic Wand has three different shapes for identifying:

nodes

edges

empty space and surfaces

Magic Wand Examples

Activate the Roof tool (Multi-plane method) and click with the Magic Wand on the edge of the Wall to instantly create a Roof whose pivot line traces the Wall polygon.

Activate the Fill tool, then click with the Magic Wand inside the empty area denoted by the curved line, to create a Fill of that shape.

Hints and Tips

New elements use the current default settings of the corresponding tool. You should always check that these are correct either before or after using the Magic Wand, especially if the elements are intended to have a specific relationship to each other, such as a roof resting on a Wall.

You can refine the Magic Wand function by selecting one or more elements. In this case, the Magic Wand will only take the selected elements into account when searching for chained elements or a bounded area.

When creating curved Walls and polygon-type elements based on Arcs, Circles and Splines, the approximation is defined in Magic Wand Settings.

See Magic Wand Settings.

The new elements are not linked to the originals and can be manipulated independently.

If Offset or Multi-Offset has been activated, you can complete the offset function after the Magic Wand has created the new polygon.

If you are creating a single Roof, you must first draw a pivot line and define the pitch before creating the polygon with the Magic Wand.

If you are creating a Fill with a custom origin, you will first generate the polygon with the Magic Wand, then draw the fill orientation vector.

Using the Magic Wand to Add/Subtract Polygon Shapes

Use the Magic Wand to add or subtract the shape of an existing polygon (of the same or a different element type).

1.Select the polygon from which you wish to subtract another shape. In this example we want to subtract a polygon from a slab.

2.Choose the “Subtract from Polygon” icon in the pet palette.

3.Move the cursor onto the polygon that you want to subtract and activate the Magic Wand (press the spacebar).

4.Click to complete.
