How to connect curved Wall to straight Wall?

Anonymous — Fri, 29 Oct 2010 07:59:41 GMT

Hi,

i'm new quite new with ArchiCAD and have a connection problem you can see as attachment.

I have a curved wall that should connect with a straight wall? Have tried several reference line-combinations, but none seems to work?

Can anyone help me, please?

Thanks!

Dave:

It would be helpful to post the same screen shot with the On-Screen Display Option of Walls & Beams Reference Lines set to on.

You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.

As David implied, the reference lines need to be able to meet. If you switch the reference line of the straight wall to the other side then the Intersect command will let them join.

Thanks for the advice! I use Archicad SE2010 on WIN 7 Professional. Normally I added it to my profile.

I added a new picture with the on-screen view option selected. What can I do to let them intersect?

Thank you very much!

The curved and straight walls as you have shown them, are not going to clean up as you wish. While you may be able to FAKE it several ways, to me it makes me step back to look at what you are trying to achieve.

Our models are virtual models of what will be built. When I look at the curved wall neither of whose edges meet at a tangent with the straight wall, I would rethink the wall materials and/or the placement of the curve relative to the straight wall.
You need to resolve the curved to straight joint. If both have masonry construction where they meet, is this poured concrete or block units? If block you need to think through how the straight and curved blocks will meet and minimize how many of the masonry units would be chipped away to achieve this look.

Alternatively you could fake the joint and where the two walls intersect by furring out one or the other wall and have the finish only be continuous.

As an aside, placing the reference line in the center is typically not done. It is hard for the computer to know which side is the inside or outside. There are times when laying out walls this is appropriate, but this situation does not look like such a situation. Masonry construction is usually laid out from one side or the other.

Dave,

Erika is correct about what she says. It is hard to interpret what you are looking to achieve from the little you have presented. Perhaps you could illustrate it with a manual sketch. I have drawn some variations that come to mind when you describe that you want the walls to join. See attachment.

As Erika mentioned there are ways to cheat, meaning the model has been patched to display something in a desired way. In the attached image I used a fill to cover the area where the two walls overlap.

This takes something away from the model integrity, however, I have heard countless times where a making a quick 2D fudge has priority over taking the time to model it correctly either because time is short or the particular job may not demand the model accuracy to be incredibly high. Just beware that cheating could come back to haunt you later on.

To clarify: the computer / AC never has a problem knowing which is the inside or outside of a wall. But, the user may have a touch time with some reference line offset positions. Looking at the arrows (disable cleanup) gives the direction in which the wall was "drawn", and lets you pick out the inside/outside faces.... unless the Modify Wall > Invert Direction command has been used.

Centerline construction is common with log walls.

So is the Inside "drivers" Left?

I used a fill to hide the line...fake but efficient and quick. I needed it to look like NCornia's 2nd option.

Thank you very much for the help! I really appreciate this as a AC newbie!

Glad to be of assistance. Happy drawing!

Can someone explain how to do the 'fudge' mentioned here? It sounds like it answers my previous post about 'patches' ?

Thank You

debjayne:

Just use a Fill that matches the fill of the walls and draw it to cover the line(s). You may need to use the Display Order (Bring Forward, Move Backward) to get the fill to cover the walls. This is a 2D solution, it has no effect on the 3D model. The Patch solution is more complex, involving the creation of a custom library part to do this job, but the Patch can more easily be reused for multiple identical instances.
