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

It's really strange to have all the very little wall segments
Here you can find your pln with less segment but with the same 3D :

I think the problem came from these segments

It is definitely due to the segmentation. I have had a similar issue when magic wanding complex shapes and when using the railing tool to create sloping retaining walls. I got around the complex shape by reducing the segmentation, and got around the railing tool by changing my reference point to a higher point further from the pivot points.

The OP is modelling from "As Built" drawings, so the project has already been implemented. A learning exercise?

Warning this is a 2D plan statement. It is not a realistic model but a 3D interpretation from a map. Therefore it is likely that the walls are not perfectly straight from the floor to the ceiling. In conclusion it is very likely that there is a difference between representation and reality: the suppression of certain segments remain my best advice

The problem stems from there being so many walls (segments) that are joining at slightly different angles to other walls that are really too short to trim to.
It is a bit hard to explain but basically the trimming of one wall is affecting how the next wall trims.

This doesn't really fix the problem -it just hides it a bit.
Select the bits that are extending, and reduce the junction order of that wall.
This will affect how the walls trim together - the higher number walls will dominate.


Is there a reason why there are so many short walls not in line with each other?
Is it really built this way or were you just tracing over a very bad plan?

One straight wall instead of all those short segments and the problem is solved.
Or as Ling suggests, at least reduce the number of segments - join some of the shorter ones into one longer wall.

The other thing you can do (but it is really not the best idea either) is to turn on the Legacy mode (OPTIONS menu > Project Preferences > Legacy).

This will stop the walls trimming by building material strengths and will simply mitre the connection between each wall.
But read what is in the little information button next to the setting to see what else will be affected.

Sorry Christophe,
You suggested reducing the the segmentation before Ling.
I was just trying to clarify what was happening and only skimmed back a few post and saw what Ling had written.

Hello Christophe, any luck with the model?
