Often, when creating technical documentation (drawings), there is a need for showing a 3D Wireframe geometry on drawings, e.g. when we want in a certain view or section to show the geometry that is rotated in relation to that cross section. Next, if we want to make a cross-sectional view of the circular contour containing ribs, and the cross-section itself passes through the rib, CATIA will automatically add a hinge through the rib, which is not a correct.
The following example shows how to add Wireframe geometry (created in 3D) to the drawing, and with this geometry, modify the hinge so that it does not include ribs. The picture below shows the casing with ribs
Now, using the Intersection
A new window will open. by clicking OK, that will warn us about multiple results (Multi-Result Management) and it is necessary to choose one result or to keep all elements.
We can only keep the right side since the cross-section of the drawing is only done in that half of Part. We select the first option, then OK, and it is enough to click on a certain geometry (for example, the edge) next to the geometry we want to keep (if the Near, default option is enabled)
Now we get the desired Wireframe geometry in the right position. We return to the drawing, so in the Properties of the cross-section A-A, we turn on the 3D Wireframe option (picture below).
After updating we have the situation as in the picture below.
It is still necessary to wipe the generated hinge and manually add a hinge that does not include the rib.
