Modelling Best practise tip – part 2

As noted by Jay Zallan on twitter, my previous post actually didn’t provide an exact answer, but in many ways that was the reason for the post, remember the skin a cat part?. :-) But what Jay did do was start a debate about potential ways to solve this issue & this crowd sourced a great discussion, so thank you Jay. I always liked to be challenged, as whilst I have knowledge in the use of Revit (hopefully) there are many ways to do things & I love to capture everybody's thoughts, one of the beauties of twitter & social media. So the conclusion from the debate was as follows & btw I am not taking credit for this. This goes to all those that challenged the post I made; they are the real hero's here.:-

  • Edit sketch profile is bad, causes too many down stream issues; probably very true in many cases. but not all situation. Use with care.
  • Whilst the 4 wall solution provided an answer, its was probably not the best configuration. Instead model the walls as indicated below. Thanks to Robert Manna for this suggestion. This approach not only provides good wall clean ups, it ensures quality IFC exports.

  • Wall joins from the wall configuration above…nice clean ups.

As a test & thanks for Rob at BondBryan for this, if you IFC this configuration from Revit, whilst you end up with 4 walls, when you IFC the result back into Revit, the model comes back perfect. Even the wall joins are good,

Using edit wall profile, IFC the walls, its fine in an IFC viewer, but re-import into Revit & you get a real mess. I would guess its the same for any other <insert preferred BIM application here>.

Hopefully this crowd sourced information will be useful to you, but even the, remember that cat, as it probably needs a new skin.
