Question about wall interconnection

Daniel_He — Mon, 11 Oct 2021 14:11:43 GMT

Hello, when I am learning one problem happened. I drawed an interior wall surrounding a concrete wall using chained Geometry, but the conner interconnection showed as marked red circle in the picture, but if I drawed wall just in a blank place showed as on the right of picture, it was correct interconnection. The concrete wall was showed as the left of picture. I didn't find the reason, so I am seeking help here, thanks a lot

It looks to me like interference between your complex profile foundation wall and the interior wall sitting on the top of the footing. Are the two types of walls on different layers? If so have you tried setting the priority of the interior walls to be greater than the foundation walls?

Cheers,

Just to clarify.

Walls will automatically try to trim with other walls (and some other elements (slabs, columns).

Stronger Building Materials used in the walls will cut weaker ones.

Unless you have the walls in separate layers.

Then you can give each of those layers a different Intersection Priority Number in the layer settings.

When the layers have different numbers, the wall will not interact with each other.

Or you can have them all in one layer and set the IP number to 0 (zero), then nothing in that layer will trim with anything else.

Thanks Barry and Gerald. In my first post, I set them in the same layer named wall interior. Now I changed Foundation wall to another layer, section No. is 1. And interior wall is still kept in the initial layer but whatever I changed section No. to 2 or 0, the result showed as below picture.

The materials priority setting is that interior wall stronger than foundation wall, but no effect

Actually, zero for the intersection priority number is probably not a good thing because even the same walls in the same layer will not trim with each other.

Unless you want that of course.

Is there anything else in that internal wall layer that may be interfering with the walls?

Something that might be visible in 3D but not on the plan?

Also try setting the layer IP number to an unused figure like 50 (you can use 0-99 from memory).

You may have other layers with an IP of 2 and they will be still interacting with that internal wall layer.

You want that layer IP to be distinct from all other layers if you don't want it to trim.

Where are the wall reference lines? Overlapping reference lines in walls can cause problems like this.

Have you tried offsetting the reference line to the external edge like the second image below?

Hi, I changed reference line offet to 4", it was interal wall thickness, then it is showing right. Thanks a lot
