Cable tray wrong direction bug

edgars_miskins — Mon, 08 Mar 2021 08:20:27 GMT

This is most certainly a bug.
Cable trays have no directions. Every direction should be a correct direction.

Are there any easy workarounds? Is it possible to manually force-change this "direction", so that the tray connects as it should?
Aside from deleting the entire segment and drawing everything from scratch with a hope, that this time Revit will happen to assign correct directions..

since no one else is replying..... i haven't seen that particular error before, but i have seen some interesting ones when Revit doesn't have enough space to put in the fittings. You probably already have a workaround by now, but try pulling the end of the upper horizontal run back a couple feet, then try making the connecting. Also, try moving the try up an inch or so and see if it will make the connection then.

This happens to me with conduits as well; see advice from @hmunsell... that's usually my issue - not enough room for revit to make the required fittings.

Thank you for the reply.
I am aware of the situation, where there is not enough space for the fittings. In that case Revit says exactly that and just like you said - it can be resolved by moving stuff around a bit.
But this is not the case. This is purely to do with some inherent "direction" of the tray. It's impossible to join these trays no matter how much space I give them. Sometimes Revit even tries and comes up with some crazy solutions just to have this "direction" be aligned or inserts some weirdly shaped fittings, like this one:

Again - there is enough room for the tray to connect normally. This is just Revit doing some weird stuff.

The only two workarounds, that I'm aware of, are:
1) Of the two joinable sides, delete entire one side (including all the fittings and other trays connected to it) and create that side anew from scratch (and hope, that Revit will guess the direction correctly this time).
2) Leave the trays unjoined. Create the needed shape and don't bother connecting the pieces where Revit throws errors about directions or does some weird ****.
Like this:

For the second one, you might think - just connect the two pieces, they're perfectly aligned.
Just watch what happens, when I try to connect them:

would you be able to upload the model, or a portion of it, for us to look at?
