Cadfixing transcript:
In this demonstration a few solutions are shown to fixing problems with imported geometry. Specifically, we will focus on the stitch and path
sweep tools.
We start by importing the model, go to File, Import Geometry, Parasolid. By just looking at the model there are no obvious errors, but
CADFEKO is showing a yellow exclamation mark next to both parts. This warns the user that there are problems in the geometry. Let’s start with
GeomImport1. If we go the detail tree and scroll down we see there are a few faces with warning signs next to them. To help us view the
problematic parts, switch on the transparency mode. If we position the mouse over one of these faces, we see a message displayed
saying:”Face is self intersecting”. If we right click on the face and select “Zoom to selection” the face can quickly be found in the 3D view. To fix
this face, start by copying the face out of the detail tree. Now Face43 has become a part on its own, but still with a faults message.
To focus only on Face43, hide the other 2 parts in the tree. We will fix this face by projecting it onto a new surface and then stitching this
surface and the original part together. We position the workplane on Face43 by using snap to geometry point. We can use 2 points to place the
workplane on top of and level with Face43. Also change the grid spacing to 0.02 each. Now we switch on the grid and a draw a new polygon
around the Face. Use snap to grid and draw a polygon of any size bigger than Face43. If you are not familiar with the snap mode, it is used by
holding CTRL and SHIFT together and left clicking in the 3D view. To make a new surface out of Face43, highlight Face43 and click on project and
then Select Polygon 1. Now delete the face of Project1 that we don’t need. Project1 now consists out of 2 faces wheras the original Face43 had
only a single problematic face.
Let’s go back to GeomImport1 to fix the other faces. The next face on the list with a problem is Face141. If we zoom to selection agai
