When using imported meshed or you have edited the mesh manually, it can often occur
that the mesh contains duplicate elements.
Select the model mesh using one of the following workflows:
In the 3D view, select the relevant mesh
part.
In the model tree, select the relevant mesh
part.
On the Mesh tab, in the
Repair group, click the Remove duplicates icon.
If duplicate elements have the same label, CADFEKO deletes all but one.
If the duplicate elements have different labels, you need to specify which
element to delete. The duplicate elements are displayed on the Remove
duplicate mesh elements dialog. For each set of duplicates, the
element with its label highest on this list is retained and all others are
deleted.
Press Ctrl and drag the numbers in the left-hand column to change the order of
the elements.
Press OK to re-order the elements and to close the
dialog.
