Wall anomolies

Anonymous — Wed, 24 May 2023 06:10:52 GMT

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

Hello,

Did you try to enter a lower value for walls that are not correctly represented in 3D?

Thank you so much for your reply Christophe, but unfortunately if did not fix the problem.

Have you checked the continuity of the reference lines of the walls ?

I do not know quite what you mean, like I said I just started yesterday. If you are asking me if the wall is continuous, no it isn't. I kept drawing it in segment. Simply because everytime I click on another window on my pc what I was drawing kept disappearing.

I mean to check this parameter : "View/Option screen view/Wall and beam reference line"
Can you verify the continuity of your wall reference line

indeed I just checked and it seems to be ok.

I have attached pictures and as you can see the problem is around the red circled areas

I see strange and very small wall segments that may be unable to connect due to lack of sufficient length
These segments are they modeled voluntarily ?

Hello Christophe I appreciate your patience, "voluntarily" I do not understand this term. As I said I just traced over my dwg file which I apploaded. I was wondering if I could just send it to you via "we transfer" and you could have a look at it, maybe there's a setting I'm missing and just tell me how you fixed it, if you can, cause like I said it's my second day with this software. Would that be ok with you?

For sure
Send me
It's a great idea

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.

Hello,

In the implementation of the project, it is likely that these segments will not be

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?
