skew in horizontal plane

Anonymous — Tue, 05 Nov 2019 08:12:39 GMT

Hallo,

i'm trying to make a as-Built model for a client, but i stumbled upon a problem.

The walls in this model have a skew in the horizontal plane. and in some places on the wall there are bumbs that don't go from start to end but are local. the client needs a precision around 5mm.

Is there a way to model this?

thanks!

Can you show some photos or sketches?

How was the wall measured in order to create an as-built plan. If your client needs an accuracy within 5mm, this will need to be surveyed. If you can obtain a point cloud model you can model it accurately.

just a example. it's small but i hope it's clear to see.

cut vertical

cut horizontal

Where does that information come from? Or rather, what format?

we've scanned the location ourselfs and after connecting the scan files we exported it to a RCP file to import it into revit.

so the data file is a .RCP

Do you have a Points File? Can you not create the walls from that?

Here is additional information on using the RCP file.

We've inserted the pointcloud into revit and made the model from it. but the problem is that i don't know how to model it correcly and accurate. changing the wall profile doesn't work.

putting a sepperate object on the wall could ,may be, be a possibility. and building the wall from a mass form doesn't work

I think perhaps you could just model it as an in-place wall, you could then do it as precise as you'd like.

in place modeling this form isn't possible. a in place model can only be one form and then extrude the required length.

but the wall isn't the same over the entire length so thats the problem.

or i'm doing it wrong

You can use all in-place modelling forms, you could make any wall shape you'd like. Not just a single profile extrusion, you can also join multiple extrusions/blends ie. and/or cut those with voids while in edit mode. Anyway, not sure if it's what you're after here but it should be possible to get there this way.

Hello,

I think I had almost the same problem: I had to model an irregular wall and I used an in-place wall, which seems to work quite well. However, at the moment I'm struggling with its stratigraphy. I can't find out how to assign stratigraphy to an in-place wall. It should be made of bricks and plaster, but I can only give it one material.

Is there an easy way that I'm not seeing?

Grazie!

You can assign several material parameters to multiple extrusions/sweeps/blends etc. Click the extrusion geometry, in properties next to material click the little box to associate new parameters (instance/type) for each material used.

Thank you for your fast reply!! That could work! Will it be interpreted as a layered wall? I mean, will its structural behaviour be the same of a built-in wall?

Grazie again!
