Solids Builder - Subtract Regions

Subtract Regions - Subtracts the selected regions from a region:

This activity is used to compose a complex region, for example, to draw a manhole and cut holes in the wall where the pipes connect:

The Subtract Regions activity has the following properties:

• Identification
  • Name - name of the activity
    The activity name must follow the naming rules
  • Object Visible - indicates whether the resulting solid will be drawn in the preview
  • Region of origin - name of region of origin, from which regions selected in the list will be subtracted
  • Regions to Subtract - indicates the list of regions to be subtracted from the source region. At least one region must be selected

The Subtract Regions activity requires a region list editor. This editor is the same as the activity Polyline:

The buttons have the following functions:

• Move to Top - moves the selected items to the top of the list
• Up - moves the selected items up by one position
• Down - moves the selected items down by one position
• Move to Bottom - moves the selected items to the bottom of the list
• Add - adds the items selected from the left list (available points) to the right list (used points)
• Remove - removes selected items from the list on the right (used points)
• Select All - selects all items
• Invert Selection - inverts the list selection
• Apply - applies the list selection to the activity.
  To have it drawn with the chosen items, click on this button

If the text gets too big/small, or the sphere that represents the point gets too big or small, use the buttons ( A, a, , ) at the top of the screen to change the preview
