Wall intersections and wall composite cores

[Anonymous]

I have noticed that when I have cores of composite walls that are slightly different (i.e. 2x4 and 2x6 stud walls) the cores do not intersect but instead the finish carries through the intersection. Is there a way to fix this? Also when I sned a CAD file to my structrual engineer who uses autocad he would like to oly see the structural walls without the finishes. Is ther a way to see only the core (structure) of a composite wall and not the whole wall? Thanks in advance for any help in these matters.

Are you using different fills to define the 2x4 and 2x6 cores within the composites? This would cause your problem.

Another possibility is that your core definitions are out of whack. If one of the GWB finishes is defined as the core (and the framing is not) this could also cause the same result.

Also when I send a CAD file to my structrual engineer who uses autocad he would like to only see the structural walls without the finishes. Is ther a way to see only the core (structure) of a composite wall and not the whole wall? Thanks in advance for any help in these matters.

This is not presently possible (though some clumsy workarounds come to mind), but it would make an excellent wish list item. A display option to show the cores only would be a nice feature.

Would you like to add this to the list?

I think this is a great idea. It would make the ArchiCAD extras easier to use as well.

For example, right now the wall framing "extra" gravitates to to one side or the other of the reference line. This forces the user to conclude that there is only one place for the reference line to be located. However, the reference line can take on several roles in the design/document/detail articulation of the work.

The location of the reference line referred to in a sister posting can take may places depending on what you're doing. For example:

in renovation work - reference line on the inside of exterior walls when this is where the on site dimensions are derived.

in new construction - there are two locations for the reference line that to me seem ideal. These would be the face of stud wall constriction to make aligning a foundation or other wall construction more sensible. Offsetting the reference line from the face of the wall also allows for very fast alteration of the wall assembly (interior or exterior) without substantial redrawing.

OR

the reference line can also be regarded as the air barrier to help establish its continuity from one assembly type to another. (doors and windows should also respond to this reference line as well to make sure their placement in the wall avoids thermal bridging and other nasty membrane to opening problems.

I can have one, but not the other as the substrate for the air barrier doesn't always align to the foundation. By having a reference line and a "show core only, I might be able to do both.

Two or three (four - fourteen?) different uses of the reference line currently necessitate workarounds to keep all the different components of the virtual model working. I don't want three sets of walls to keep all of these tasks going.

BTW - there is a setting to show only the reference line of the walls - its in the preferences, I believe.

Great thread. Lots of issues wrapped up in this one.

This was put in the wish list last December:

And here is poll about composite joints also from last December. I posted an image there that I think goes right to David’s original issue.

Sorry for the delay in responding to your suggestions. I had been on vacation. I did try what you suggested and changed all the wood stud walls to the same fill pattern and that worked. Thanks again for your help.

One note regarding that. I do lose the information about what size studs and their spacing but that is not that important. I am curious to know if the ability for wall cores to intersect and clean up is related strictly to the fill pattern and if so is it the bit map, the vectorial or both? Can one have different materials with the same fill pattern assigned to them and and have these wall cores still intersect?

Also you mentioned a wish list. Where can I find that list. I do think the ability to turn off all layers (skins) of a wall except the core would be very helpful when dealing with structural engineers and perhaps with others. It sounds like this may already be on the wish list. If not I would like to add it.
