Can conduits link to the center of the inlet instead of the walls of the inlets?
Yes, you will need to omit the connection regions when defining the cells. The connection regions are defined in the bottom cell and can be surface elements, shapes or solids defined as construction class and line style 6
OK, but I ave configured my cells to connect at the face of the vault, which I want to happen. The problem is that they always connect to the center. What's wrong?
Of course, the first action is to double check your feature definition library and cell libraries to confirm that the connection regions are properly configured and that the feature definitions are loading the cells that you think they are using.
But, then check you Accusnap settings. Make sure that the check box to "Identify Elements automatically" is ON .
