It would be nice if a footprint would automatically attach to the din-rail. Now the inserton point of a footprint seems to be the lower left corner point which makes it difficult to insert it to the correct location. Also wipeouts in those footprints would mask all what is behind the footprints.
We put a line on the footprint block that represents the din rail center line. the insertion point of the footprint for all din rail components is always on the farthest left of that din rail center line (then things can be stacked next to each other... (like PLCs, fuses, circuit breakers). If you need clearance zones then the din rail line extends to the edge of that and the insertion point should be there then.
We have added wipeouts to all our din rail footprint blocks.
We don't use any "out of the can" blocks, we have created all new custom footprints based on MFG drawings.
Panel creation is manual in that you must place them... make your blocks such that you can do that.
I would like to see footprints have the capability to "lock" with similar footprints as well as attach to the din rail. My example would be terminal blocks, how they join together in real life I would like to see a sort of a "mate" between two similar blocks.
So if you had a group of terminal blocks on a schematic page they would come in as a single group on the layout page locked together. With this if there was any change to the schematic page, the grouped terminal blocks would be able to "slide" up and down the din rail if one items size were to change.
Um are you using out of the can Autocad Electrical panel footprints?
Most of those had pretty poorly placed insertion points as I remember, most had them at the lower left corner, which for a din rail mounted thing is useless.
We have redone, or made new, panel blocks for all our components. We determine where the insertion point is and have provided other things on the block to allow them to stack nicely together.
We have found that the din rail center line is NOT the same for all the different components out there... one would tend to think it is exactly dead center of the entire block, but, often it is not... it is offset a little bit, or more... depends on how the manufacture wants their stuff to look on a din rail.
Here is a plc rack (Rockwell, 1769), the red arrows point to the insertion points for each block, the next blocks insertion point goes on the "din rail centerline" of the previous component, that way they can stack nicely:
Here is an autocad built (out of the can...) PLC component (note poorly placed insertion point for a din rail thing):
Compare that to our custom built ones (here is a L36ERM processor):
Notice the insertion point for the block is on the din rail center line (not the middle of the extents of the block, because that is NOT where it really is), notice the din rail center line... the far right of that will allow the next blocks insertion point to stack right on it.
Here are some circuit breakers:
Note, again, how the insertion point for the next item sits on the din rail centerline of the last component... this way they stack easily.
Also wipeouts added to hide dinrail behind those objects...makes the panel looks really nice.
So if you are using your own custom panel footprints you can decide how easy it is to stack them together.
If not, then you are at the mercy of whoever designed the footprint.
I will repeat we are NOT using one single out of the can (vanilla if you will) panel footprint block. And we have no problems stacking anything.
We have customized every single panel footprint to meet our needs.
As to terminals:
We use the TSE to build all our terminal footprints, and as long as the blocks that it calls are correctly built they stack up nicely to each other in the TSE at panel build time.
If your terminal footprints have insertion points that do not line up, then that would need to be fixed.
We have touched every single one of the ones we use and made them suit our needs.
