clash detection

[Anonymous]

This was a prelim sketch from bid time that was not really detailed to any great extent.  There is actually a little more geometric funky stuff going on.  The scope includes a special provision that the last 26 feet at the brownish portion be modeled with a clashed detection software.  It's packed with rebar, embeds, post-tensioning sleeves etc.  I've been on AutoCad for years and when I looked at Revit it looked completely different.  I have no desire to learn a new interface to do the model portion.  I understand I'll have a lot of work learning the rebar and clash detection commands but the model would only take me about an hour in AutoCad.  Can I draw the model in Autocad or Civil 3d and input it in a format where it will have the same attributes as if it was drawn in Revit?  Solids or 3D Faces or simple 3d Polys?

The Interference Check command in Revit works by looking at Revit objects based on Categories (walls, doors, windows, pipes, structural, etc.).  You could draw the content as 3D CAD content and import it into Revit but the IC command will not read it.  If you explode the 3D CAD content, you lose the 3d functional aspect of it.

If you draw your content as 3D CAD content within AutoCAD/Civil 3D, you can create custom attributes to assign to those objects.  Not sure how this will help you in regards to clash detection/interferences.  

If your ultimate intention is to find clashes from within Revit, you will have to model it in Revit with Revit content.

If your ultimate intention is to show the 3D content in Revit for general understanding with respect to something else drawn in Revit, then just draw it in AutoCAD and them import into Revit without exploding.

Hope this helps.

thank you for the feedback.  Answers the question but not what I'd hoped to hear.  I was hoping someone had a magic pill.  I was really hoping to avoid learning to Model in another program when I can do it so quickly with one of the other Autodesk products.  Dan

-What is the intent of the provision that clash detection be performed? Clashes against what? Rebar to steel plates/embeds, etc?

-Clash Detection on our healthcare projects is typically run in Navisworks on major MEP systems vs Structure--say Piping vs Beams, etc. Our Revit models are imported into Navisworks which has purpose-built "Clash Detective" toolset.

-Not sure if Revit has internal clash tools for rebar vs other structural elements?

-Trying to use AutoCad for BIM/clash detection is not really a good workflow. This is why the AEC industry has adopted BIM/Revit as the primary authoring tool.

The end of this beam is packed with rebar. Straight bars, tie bars, longitudinal bars etc. It's got a bunch of post-tensioning sleeves, Huge embeds for the bridge arch, bearing plates, floor beams, conduits for utilities etc. The intent is to address inferences before the guys are out in the field scratching their head. We're open to just about any product, I just assumed Revit was the best for this. We have AEC 2019 and when I googled "rebar clash detection software" many of the results seemed to have Revit. Maybe Navisworks is the go to product, maybe there is an other software or other company that Autodesk works with. I guess that goes to my original question about what the team might suggest. I was hoping that whatever we used I could at least draw the geometry of the concrete beam itself in Autocad since we know it so well. I knew the rest of it would have to happen in a different program. I'm pretty much resigned to the fact that I will have to spend some time learning to build the shape in some other program before I can get into the internal components.

This is exactly what I'm looking for. Do we have this as part of our AEC 2019 package? If not, can you send me a link to where I can find out how much this cost and where I can get it. Thank you very much for working with me so quickly.

-Revit (2019 is newest release) has the Structural / rebar Tools built in.

I appreciate everyone's ideas.  My hope was that I could just draw (outline) of the concrete element and import it to a type of object that Revit would treat the same as if I had done it in Revit.  Then I could just learn all those commands.  The only reason is because I am so familiar with AutoCad's (and by default Civil 3D's) interface I can draw the outline so quick verses the hours and hours it will take me to learn Revit with tutorials that really don't apply to what I need right now and it looks so different.  I would have liked to start to get familiar with the Revit interface while learning the rebar related commands.  Then when I had more time, go back and draw some models when I had more time to spare.

Can we clash check clash check in Reinforcement through interference check? I think negative. 
Within Revit there is no option to check the clash check for rebars.
