Building sections of a polygonal object |
Scroll |
In KOMPAS-3D, the creation of flat sections is available for polygonal object. In the future, such sections can be projected into sketches, based on which a solid model will be built.
Sections of a polygonal object are created using the command Curve of intersection 
.
|
You can obtain several sections of a polygonal object within one command. Construct the planes of the proposed sections before running the Curve of intersection command. For constructing planes parallel to the faces of a polygonal object, it is convenient to use flat surfaces obtained based on these faces using the command Surface Fitting. It is also possible to obtain the necessary planes using commands for constructing a plane through three points. |
In the process of command execution, it is required to set:
•polygonal object whose section needs to be constructed (Set of surfaces);
•secant planes (Set of surfaces 2).
If the intersection results in multiple contours, you can select the needed ones.Details...
You can also set the properties of the created contours – name, color, style, and others.
After plotting is completed, the curve of intersection will be displayed in the graphic area, and its icon will appear in the Construction Tree.
An example of constructing a cross-section of a polygonal object is shown in the figures.

The intersection curve represents a set of contours, each of which is a broken line consisting of individual straight segments. In some cases, the resulting contours can be used in shape-forming operations, but more often they serve as reference objects for sketch construction. |
|
Using the Curve of intersection command, you can not only construct flat sections of a polygonal object but also obtain curved intersections of polygonal objects with each other. For this, the cutting object must not be a plane but another polygonal entity, which can be obtained, for instance, transformation of a solid or surface. |
