bad wall connections

[demetris ktorides]

Hello! 

 

I wonder if anyone can help. I am doing a scan-to-BIM project and we've surveyed an old house with crooked walls. 

 

I am having issues with the accurate modeling of the walls. The 'wall join tool' is not giving smooth results and I wonder if it's something I am doing wrong or VW gets confused in the joining process with walls that are not square. 

 

I am attaching some screenshots in case someone can help. 

 

(i've used the 'fit walls to objects' tool and fitted them to the roof..)

 

 

Thanks, 

Demetris

This is the way Walls are unfortunately. They will always be flat across their width unless you use a Roof/Roof Face to clip them. So use Fit Wall to Objects command on the gables + at the eaves you will need to clip the Walls with the Roof. Do you know how to do Roof clipping?

Hi @Tom W., 

Thanks a lot for your response. Good to know.. 

 

No, I haven't thought of that as I was under the impression that any clipping on the walls will result to them turning into solids. 

 

Could you guide me a little with the roof clipping commands? 

 

Appreciate it,

If you use a 3D Solid + the 'Subtract Solids' command it will do. But instead you can use a Roof Face instead of a 3D Solid + set it to clip the Walls in the roof component settings:

 

 

Now go to the OIP for the Roof + click on 'Pick Walls to Associate...' in the 'Wall Clipping' drop-down:

 

 

Cursor will turn to hand icon. Click on the Wall in question: it will highlight red. Hit enter or click on the green tick + the wall will be clipped.

 

So you can obviously do this using the building's roof or you can create a false roof (which you can place on a hidden layer) just for the purposes of doing the clipping if necessary.

 

One roof can clip multiple walls at once.

 

You can also do the opposite + have the wall clip the roof.

 

This is all done on a component-by-component basis so you can achieve quite complex wall/roof interface details if desired.

Aha! 

 

 

Thanks Tom! New trick! 

 

 

Best,
