Cable tray should be able to be inserted into a model in any direction or orientation as it would on site. I have been to many sites where cable tray is run horizontally along a wall from a riser and also where tray is fixed to Unistrut on the underside of a slab with the tray facing the floor. This can also apply to basket and trunking.
Also Trunking does not always have lids on the top face as the lids can be on the side.
Perhaps Auotdesk could take some of the development team out onto sites to see how the elements they have created are installed in real life and also request site photographs from CSE's in other countries, to aid in understanding how we would want to design and install the elements created in a Revit model. I appreciate that Autodesk can't accommodate every combination/possiblity that happens around the world but it may help come to a more flexible solution when using these elements.
I agree. We need the cable trays to be able to be inserted in any direction we choose. It is very common to run cable trays along walls, and also as mentioned earlier, we quite often are required to run them upside down direct on the soffit at times.
While still new to MEP, I have sen already many vertical installations. And these are very serious installations; not done in a improvised mode. Many are mounted on a vertical Unistrut grid.
Most of other installations have some vertical portions, so not being able to model it totally compromises the cable tray objects.
Has anyone found some workarounds?
(I also dare to find good Unistrut families; currently not offered by Unistrut.)
I cannot send any pics, but found this web clip from the Cable Tray Institute (http://www.cabletrays.com/faqs.html)
Is it common practice to use cable trays in the vertical position? Do they maintain their integrity during a 25 or 30 year life of a plant? Is the percent fill of a vertical tray the same as a horizontal cable tray?
(1) It is common practice to use cable trays in the vertical position. I have many photos of such installations. There is no problem. Cables must be fastened securely, see NEC392.8(b).
