Merging Walls - Help!!

griggadee — Wed, 24 May 2023 10:51:37 GMT

Hi folks,

Could you please have a look at the picture attached and tell me how to successfully merge these walls together so that there are no gaps at any point where they join?

I have tried everything but am unable to get a clean join between all three elements.

Thanks,

Paul

Here's one trick

Thanks for the responses chaps.

I followed the tip from Andro55 and this worked a treat in terms of 3d geometry so thanks Andro55. See attached image.

The composite fills still look a little poor though. Any suggestions for getting the plasterboard lines to meet on all sides?

Thanks,

Paul

I repeat,
all 3 reference lines must meet in 1 common point!
The wall reference line can be outside of the wall itself.

I hear you brother loud and clear. The references lines do all meet at one common point.

Thing is, as I said before, your method worked really well in sorting out the geometry of the walls, i.e. they all meet and join correctly now, but the plasterboard within the composite fills still doesn't meet on all sides. I will have to manually redraw this area should I need to produce a detail of it.

Any ideas for making sure the fills line up correctly?

To be honest, your tip gave me the answer for getting over my initial problem and so the fill issue is no big deal really, I can work around this. It's just handy knowing if there is a simple answer.

Thanks,

Paul

Then your best bet is the column solution that is shown in that Onland article. It will give you both correct 2D and 3D:

Paul:

You should set various Skin Priorities for the Wall Composite in the Composite Structures dialog box, then in the Wall Settings > Floor Plan and Section > Structure Enable Skin Priorities. This will give a better result.

You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.

Firstly, I must say that since moving from AutoCAD to ArchiCAD last year after 7 years of using the prior, not only am I now in no doubt that ArchiCAD is the best drafting / visualisation programme on the planet, but it also has (along with Artlantis) the best support community in the world! Thank you very much to one and all for your speedy and helpful feedback!

Anyway, David, I have created the wall composites that you see on the JPEGs and so the problem is not in there as all of the walls feature the same composite, and the 'enable skin properties' box is already ticked. Neither of which seem to sort the problem but thanks anyway. I guess it is just something I will have to live with when I have multiple walls meeting at varying angles.

Laszlonagy, thanks for the link, but by the looks of it, that workaround would only work if you have a consistent background fill on the walls. As I have a composite fill within my walls, I cannot see ArchiCAD correctly applying this to my busy wall junction. I will try nonetheless and let you know if I am successful.

Thanks,

You need to create a Custom Profile in the Profile Manager and apply it to a Column, then you need to place that into the intersection. Maybe the easiest way to do it is to create a copy of those intersecting Walls, explode those copies so they will become Fills and Lines, and copy those Fills and Lines into the Editing Window of the Profile Manager when you create the Profile for the Column. After proper placement the Profiled Column will cut itself out of the Walls and will also seamlessly join the Wall fills if they are the same.

Thanks Laszlonagy.

I have tried this method a few times now and I still don't seem to be able to get the column to cut itself out of the walls. I have even tried it with new plain walls with background fills and yet it doesn't seem to be happening for me. You don't know of any video examples out there do you?

I will try it again soon once I have met my current deadline.

Thanks again,

You also need to adjust the Skin Priority of each skin in the Composite Structure dialog box.

Bravo David! Spot on mate!

I had prioritised the outer layers before thinking that they would come to the top and show over the insulation but when that didn't work, I foolishly didn't try prioritising the insulation layer over the outer layers! So simple and obvious and yet I completely missed it!

Thank you very very much!
