Walls not joining

Anonymous — Tue, 09 May 2023 14:17:45 GMT

Hi! I created these walls with the magic tool out of a morph. The morph consists of seperate lines that are connected but are segmented.
The walls are also segmentend
How can I convert the segments to a single wall?
Merge walls wont work unfortunately

When I try to insert doors or windows the segments are too small, so a door or window will stick out at the side. Im trying to get this to function the same way as when you would have created the walls with the standard tool using round shapes.

you will have better luck with window placements in those curved walls using the Curved Geometry Method: so you don't have so many segments.

Thanks for the reply and taking the effort to make a video. Using this method it proves quite difficult for me to trace the lines right. Do you happen to know any other way to get the walls right (maybe with another program besides archicad)?

As with everything in ArchiCAD, how you model it depends on what you need to do with it.
And of course, there is never only one way to skin a cat. I am assuming that the curved walls need to be documentable in terms of dimensions for radius centers, lengths of arcs, things like that - rather than just freeform ?

Are you making working drawings/plans for this, or is it just for a conceptual model?
Also, what is the source of the lines you want to follow with the walls? .pdf, image file, .dwg...?
Lot's of things will make a difference in how you model those curved Walls.

Its a conceptual model for university. The walls only have to look right in height, thickness and in plan. I made the model you can see in my previous post in sketchup. I imported the sketchup file in Archicad and traced the borders from the sketchup file. I could also export from sketchup to dwg or pdf but I think the problem is that sketchup will always make the lines segmented as it doesn't create true circles.

The reason to use the method I showed is for the sake of fewer segments that you will get using the faster method of the magic wand. Also, by the time you rationalize (make your curves dimensionable) you will find that this will give you walls that are more appropriate for the future evolution of the model.
Some walls may have a radius so small that you need to use curved windows. Other curved walls might work just fine with straight windows. It might depend on the materials of the wall, which might be determined by the radius of the curves. What you can make out of Playdough is not the same as what you can make with Lincoln Logs... that sort of thing.

If would be helpful in making suggestions to know the scale ( if not the dimensions ) of the building. It looks like it might be a 6 story building? Perhaps you could put a 3D man or something in the model.
You can, of course, use the magic wand to place the walls with just a few clicks, but that will result in too much segmentation. That is why you will probably choose to stretch the walls into place. I would use straight walls with nodes at the critical places and then stretch them to fit the curves.

But first - work out some rational curves with precision dimensions. There are some good tools in ArchiCAD for doing that.

like this +/- a 6 story building ? https://www.screencast.com/t/vVKT1vfVmkTY

Thanks for the reply, its 14.3 meters high with split levels, its a bit complicated

This is the link to the archicad model

Or more simple sketchup model

You are right, I should have used that method, but right now I'm a bit too far in the process to it all so a quick method would be great

sounds great. I know what you mean by the need for speed Every modeling project comes with it's own set of time restraints and challenges. Which is another reason why there is never only one way to model something.

Wow. Thanks for sharing the file - that looks like it's gong to be a great project!

It should only take about 1/2 hr to replace all of the over-segmented walls in the project with minimally segmented walls. The process is easy enough that it might be worthwhile to fix it at some point ?

If your going to make some renderings it will probably be important to get rid of the overly-segmented walls. https://www.screencast.com/t/chJle8a9Pk68

Thank you for your help! Being able to fix my model helped quite a lot during the busy deadline days !

Just FYI,

You may also try to model each of these long meandering Walls using the Polygonal geometry method, instead of modeling it using a series of curved and straight Walls. The advantage of this method is that each meandering Wall is a single element and you can still place Doors and Windows into it.
