Boolean operation Intersection

Introduction

The Boolean operation Intersection facilitates the intersection between several objects.

The common part of the original objects becomes the resulting object from this operation.

Structure of the Boolean operation

The Boolean operation Intersection is described by:

  • A coordinate system for the creation of points points (active coordinate system in the list available on the graphic View)
  • A master object
  • One or more objects to join with the master object

Result

The creation of a Boolean operation Intersection of objects results in:

  • The modification of the master object.
  • The removal of the objects joined to the master object (these objects are preserved in the data base in order to ensure the reevaluation of the building tree in case of possible modifications).
  • A geometric operation INTERSECTION_1.
  • The appearance of the object resulting from the intersection corresponds to the appearance of the master object.

Access

The different ways to access the boolean operation Intersection are:

Creation of an intersection of objects

The creation process of an intersection of objects is presented in the table below.

Stage Description
1 Choice of the coordinate system of creation
2 Opening the dialog box Intersection
3

Choice of the name of the generated Geometric operation

(by default: INTERSECTION_1)

4 Choice of the master object
5 Choice of objects to join to the master object
6 Validation by clicking on OK
A geometric object INTERSECTION_1 is created

Specific case

No intersection operation is carried out unless the original objects have a common part.
