Boolean Union (form)

From Selection

Use the grid to specify the wireframes you want to perform a Union operation on. Use the buttons on the grid list toolbar to Manage the rows in the list.

Options

Use the following options to remove the internal facets and interior walls of combined solids:

Option	Description
Coplanar tolerance	Snaps together portions of the input triangulations that are almost coplanar.
Thin wall tolerance	Helps to clean up "digital noise" when almost coplanar interaction occurs between the inputs.
Short edge removal	Conditions the inputs to remove vertices that are near one another. This is not a post-processing step applied to the result.

Output

Select the Overwrite input wireframe option if you want the result of the process to be applied to the Input wireframe. If this option is selected, the following Output prompts will be disabled:

Type and Name

Specify the type and name of the Output wireframe.

Colour

Attributes

Click the Attributes button to set Wireframe Attributes for the wireframe output.

User-defined attributes may be mapped against the fields in the Input file. It is also possible to specify a default value for each attribute. Default values are used when a corresponding value in the Input file is either missing or is not mapped.

Auto load

Select this option to load the generated output in Vizex. The default draw style for an auto-loaded wireframe is 3D Shaded.

Forms

Click the Forms button to select and open a saved form set, or if a form set has been loaded, save the current form set.
