my atavico problem with archicad

[eux]

hello to all and congratulations to developers for the excellent forum;-)

work with archicad from version 6 and I believe it is a software that for extreme intuition, can induce the neophyte to think that it is limited, while those who know it thoroughly, know that for architectural design is really, really complete.
I have been part of the first category of users for a few years, but it is clear that over time and the various versions I have always had greater needs that led me to learn more and more. today, now in version 17, I think I can say that I really know the program. Then I get back some questions I was asking myself when I started using it and I recognize that everyone found an answer. All, except one. Therefore, I want to submit it. . .

the question is very simple and I think it happened and understood to everyone to have to deal with this problem.
I use the image support attached to explain the theme.

in practice: archicad thinks for floors - which is there being that even for the most bizarre architectural forms, there is always a "hierarchy z" or each building is articulated on one or more levels that can have "lights" (distance floor / ceiling in my jargon) even distinct. and so far everything ok. to create an element, whether it a wall, a loft or a ground is very simple and we can choose its height in relation to the quota 0 of archicad or in relation to the quota 0 of plan. of course to work in a "clean" way it is appropriate to make sure that the walls, the floors and how much more begin with what we consider our plan, also begin with the plan of archicad. Although it is also possible of course, that a single wall "parta" from -0.50 compared to the beginning of the plan or outlines beyond this limit. but until it comes to exceptions, no problem.

The problem came to me for the first time when I worked on a project consisting of several volumes lying on a steep terrain and connected to a certain quota by a system of aerial catwalks. Besides lying at different odds, the lights of each volume were slightly different. the problem that has been presented to me is easily understandable by the attached image.

or: archicad has lines from which the p1 begins, p2, p3, etc... if there are two volumes or in this case two buildings that are articulated on different heights, here is a nice mess!

in the figure it is seen that adapting the beginning of the floors to the building to, everything works in relation to this, but not in relation to the building b. This means that for example a wall of the p3 of the ed b, that in reality "comincia" with the third floor, will appear to archicad as a wall that "stars" from about +0,70m compared to the p2 plane! if then we talk about cutting plans the thing gets further messed up. Try to think what happens if both buildings have roofs.. .

cut the third floor and on one side you find rooms, while on the other the roofing plant!

I obviously never complicated myself more than much - to make a correct plant I do a section in axometry view plant at the quota z I prefer, except view 3d as view 2d and I have a design that cuts exactly to a quota z that I want. But if I go to look at the walls of the building b is really a mess. find things like "this wall starts from -0,5 compared to the floor, this one to +3, etc..."

I don't think that's a problem recently. I mean, I seem to be forced to create a file for every building. and if I have a building with more volumes?
Has anyone ever placed the problem and has a solution?

thanks, eugenio

clearly it is a situation that should be thorough, but I normally use the connected modules, each building 1 file.

1. I carry every floor of each building in a file form(.mod)
2. amount each module in a file that will contain them all, then in the 3d they reposition them to their correct quota. this file will have only the ground floor of high height so that you can manage the cutting plane.
3. with the cutting plan, the views and drawings connected to the views, I manage the layouts in the most appropriate way.

the reason for which I carry every floor of each building is because archicad, as you noticed has a very ferreous plan management. if you use only one module file(multipiano) for each building when the amount in the host file regardless of the settings or height or difference in height will fit those of the host file itself.

in this way the project of each building travels quietly in its file, while the batches and everything else I manage in the file with the connected modules and bypass the problem of the plans as described above.

hello paolo and thanks for the answer.

I know the method, but you will agree with me that this is also a filling. If you have to delete a wall or change it you go from 3d or worse you have to go back to the mother file. what graphisoft should do is create a system to assign a plane hierarchy only to a project area. a command type "selecting area" through which you select different parts of the project in plant and to each fix a hierarchy of plans. then the cutting plan could be chosen in relation to an absolute system in which you choose the quota z, or in relation to the "plant system" of each area.

Yes, but I don't see the problem.
personally if I'm thinking about the lottization I don't care at that time focusing on individual buildings, and vice versa if I have to edit/delete a wall of a building means that I'm working on him and at that time I don't care about the lottization.
At least for me are different stages of work, today I do one thing and tomorrow (not in 2 minutes) I do another.

what graphisoft should do is create a system to assign a plane hierarchy only to a project area. a command type "selecting area" through which you select different parts of the project in plant and to each fix a hierarchy of plans. then the cutting plan could be chosen in relation to an absolute system in which you choose the quota z, or in relation to the "plant system" of each area.

I do not see alternatives.

the problem is relatively negligible if it is different buildings that do not have relations between them, or as you say struggles and similar. but I repeat that the first time I understood it was the same building consisting of two volumes lying on different quotas. at that point it is not very convenient to have to set walls starting from -1mt or set the cutting plan to different quotas depending on what I want to see
