Stair and Wall SEO PROBLEM

[Anonymous]

Help really appreciated.

I am trying to use SEO with upwards extrusion a wall with the stair.

Although both have same material and the wall is placed at the borders of the stair at the elevation I can see the cut line of the two surfaces.

Normally both surfaces should look as one.

Is this a bug. Is there any way to fix this without adding lines or fills at the elevation??

Thank you

Others may offer a better solution, but I am not optimistic that a wall can visually 'merge' with an object like slabs and walls can.

When faced with this situation, I turn the wall line [uncut line pen] to white since there are usually other walls defining important edges.

Hi Dwight. Thank you so much for your answer.

You are right with the the slabs. The SEO upwards extrusion worked always as expexted with walls and slabs. The cut line dissapears, giving a normal, correct elevation.

But with the stairs this is obviously a bug. If both stair and wall have same material then there shouldn't be any line between them. Changing the cut line of the wall to the same grey is not a solution as I need the left side to be black because it will be visible.

I have thought to draw a line at the elevation to cover the black one, but the thing is wether this can be solved with a certain setup or adjustment and not a trick.

Stairs should work as slabs so I consider this a problem which has to be solved by Graphisoft.

I was going to say that stairs are actually GDL objects and object surfaces have never merged with like surfaces of walls or slabs.

But I just tried it out of interest (version 16) and the merge line can disappear if the edge surfaces are the same material.

This is a stair object I created (ie scripted myself) so I don't know if this works any differently to a GS stair in this reguard.
Just swapped for an old GS stair I had and the line appears - exactly the same SEO .
I don't recall doing anything special in the scipt for the stair but it was I while ago that I made it.
I have tried SEO with a cube object and the line can't be removed there either.
I must have done something in the stair script.

Not that this will help you as I am sure you don't want to re-script the stair objects.
But now you have got my curiosity up and when I get some spare time I will look into it further.

I always thought objects and walls would always show a line when SEOing.

Thank you Barry.

The wall and stair have exactly same material but the line is still there.

At your case, has the line dissapeared in Archiad 16?

I tried to make the wall a morph and check and resetup the edges but the line is still there. I am considering that the only solution is to add a simple line above, at the elevation.....

Yes the line has disappeared in my case but as I said this stair is an object I created.
I tried the same with an old original Archicad stair object (Qiuck Stair) and the line was there.
The difference I have noticed is that my stair is a solid PRISM and the Quick Stair is scripted as just surfaces.

Even using the "Create Stair" option leaves the line - although you can control the colour of it - so could make it white.

I would just add a white line to the elevation as you suggested if you can't control the pen colour of the object.

Even when I use the simple "Cube" object (which is just scripted as a BRICK) the line is still present and can not be hidden.
This is as far as I have gotten with the investigation so far.
