Wall anomolies

[Anonymous]

Good Morning people, I am very new to Archicad, in fact yesterday was my first day trying to do anything on it. I have attached an image of the problem I am facing.

So I am trying to draw an as built survey of a basement, the walls are not straight at all, so as I am tracing around my dwg I get this weird thing happen to my wall, I have no idea how to fix it. on the 2d floor plan it looks perfectly fine but in 3d it is messed up. could someone please help?

Also I deleted the walls from that section and tried drawing it again and it joined to the wall on the other side (see image).

P.S. I am very green to this, usually only work on 2d cad drawings

Barry, thank you so much for very much for pointing that out to me that there were replies I wasnt getting any notifications. Thank you also for your demonstration. I now more or less understand what Christophe did.

And to Christophe thank you so much for your enduring patience with this novice.


This is was a basement that was surveyed and I am trying to produce a 3d model of that survey. My first model, still trying to figure out how the software works exactly. So many options.

Go into your profile settings and hunt around for this.
Make sure you have e-mail notification ticked for 'Someone replies to a topic to which you are subscribed'.

Thank you Barry.

I have another question, now that I have my walls is there a quick fire way for me to generate my slab and ceiling from the outline of the wall or do I have to trace around again to create them?

Read up about the Magic Wand option if you haven't come across it already.
SPACEBAR is the shortcut key.

You can flood an area and it will automatically look for bounding edges (walls) - but this won't work unless they are all joined with no gaps.
Or you can click on the wall edge and it will follow the walls - but again they all need to be joined and it will get confused if you have two wall branching from the same point.

Neither is fool-proof and sometimes it is just as easy to manually pick your points.
Or if it doesn't quite work but is almost correct, don't forget you can adjust the shape of the slab rather than re-doing it.

Also remember you can use the offset tool in conjunction with the magic wand, so you can use the edges of the walls (or flood) and can then offset a desired distance from those edges.
Or you can just select the slab afterwards and adjust it.

wow. that magic wand just changed my whole life. I am still a bit confused on how Christophe was able to fix that because initially I had changed the junction order reduced it and it did nothing. I see he mentioned reducing the segments is what fixed it and im trying to look online and cant find how to do that.

When he said he reduced the segments, he meant he deleted some of the shorter walls and joined the adjacent walls to close the gap.

Basically the walls are too short when they are at very slight angles to each other and this affects how they trim - now that we have the new building material / skin trimming method (that is why the old legacy method works because it doesn't trim each skin).

Reducing the number of walls (segments) makes them longer and they will tend to trim better.
Also if the angles weren't so similar between each wall that would also help.
You just have the perfect storm of short walls that aren't quite straight.

Ideally you should have one long straight wall rather than lots of short ones.
But if the wall is not actually straight then you have no option except to use many short walls.
Just try not to make them too short.

thank you once again.

in the situation where many wall segments are not manageable or desirable for one reason or another, you can consolidate them into a single Morph. To add doors/windows/openings to the Morph you can use the Cube object as an Operator with Solid Elements Operations to make a hole (any element or object would work but the Cube is easy to adjust in all directions) - put a wall in that hole so you can place a door or window in it. The you can reduce the wall height to .01" and make it some tiny length if you don't want to see it - the door or window will still display correctly. That is how you can (if needed) place a door or window in a Morph. Not something you need to do very often but it is something you might need to know someday.

Another way you can get fewer wall segments for a crooked wall is to use the Polygonal wall placement method. Essentially use the polygonal wall setting for a non-composite or complex profile wall and stretch nodes of the wall to all the nodes of the segmented walls. This will give you one wall of a crooked shape - if that is what you prefer. Nothing wrong with all the walls segments as long as you can manage them for all the intersect and clean up issues.
The Polygonal wall is how I would do it - and place the polygonal walls using the magic wand- your new favorite tool ( For each skin of the crooked wall). You can't do this with the Trapezoid wall. That just makes segments between any nodes you may add.

I should probably add that if you explode the segmented walls you have they will become fills and you can use the magic wand to convert those fills a single Polygonal wall. You may still want to keeps a few of the segmented walls for other reasons.
