AC 17 Building Materials

Erich
Contributor
I am just starting to create a template for the new AC 17 and am now attempting to wrap my head around the building material attribute. Does any one have a clever idea or best practice for organizing this new attribute?

While it seems to fix a number of things and is quite powerful, it also seems like it could get unwieldy quickly if not well managed.

I am hoping the community (at least the beta testers) might have some good information to be shared.

I think what you could do is make a list of the most important real life building materials that you use in your Projects, such as concretes, insulations, etc. Then create the equivalent Building Materials attributes for all of them in your Template file.
Most probably the hardest thing to decide will be what Intersection Priority Number to assign to each of these created Building Materials.
I think the default ArchiCAD Building Material attibute set give a good base to start from in this regard.

The info GS provided in the videos and pdf's should be really studied. There are several major things to be mindful off when building your template. My work deals with the constant use of plns created many years and updated through the years (I still have acive plns from the mid 90's). This is by far the biggest change I have had to deal with, however, at this point it is pretty easy and straight forward. I am very happy about this change.

Remember all your favorites need to be carefully examined for consistency. Before walls and slabs (etc) could use fill overrides, but not now, so any Favorite with overrides will generate a unique BM. Same with any default setting, and any placed walls/slab etc. I spent a lot of time first thoroughly rebuilding all my composites and Complex Profiles, along with renaming Surfaces and fills so I could tell where things were coming from. Consistency is the main thing. All drywall should have the same exact fill, pen, priority etc or opening in a new file will create way more building materials than you expect. I had become sloppy over time so I had a mess to clean up.

The delete/replace is worth the price of the update alone. It will quickly eliminate near duplicates. Attribute Manage is something I use daily. Be aware of what will produce unwanted BM's, such as the "stock" Complex Profiles. When I migrate a file I first open AM, and purge somethings (like Complex Profile) and override everything.. well.. composites, fills, surfaces and CP's.

A clean template is very important to migrate existing files. It is worth a complete cleaning and reworking for absolute consistency of fills, surfaces and priorities. Then use delete/replace to clean the migrated file. So, the Template is worth a lot of attention first.

I changed most fills that were generic ~ "50%" as an example ~ to an identifiable name. So, I duplicated and renamed Surfaces and fills to make that work as needed. Again, I had gotten pretty sloppy, so maybe you want have as big as mess:)

I last updated our template (created new from scratch) in AC 15, and brought that into 16 with no troubles. Now I'm thinking of starting new as Rick suggests because of the Building Materials. I have about 100 right now, and it is chaos.

I agree with you Erich, it could get out of hand quickly.

For example, you cannot have just one GWB material. What if you want yellow gwb in one room, blue in another, and so on? You need a new material for every different surface, correct?

This means dozens of materials for different types of siding?

You really shouldn't need different BM's for colors as you can override the surface as before. I did not start over with my template and it is just fine, so you might want to convert first and see where you are. The "delete and replace" feature is a life saver and makes this process pretty fast. You can easily open Attribute Manager and purge unused first, should that help.

Ok, make sense. Though if you override the surface, you lose the ability to see different surfaces on a cut element in 3D, correct?

On another note, I see that through the complex profiler, you can still assign different surfaces to any side of a fill.

Steven,

Surface Overrides have no effect on the cut surfaces of elements in 3D. They continue to display as the cut surface based on their Building Material setting.

Surface Overrides affect only the outermost surface of an element. So for example, in case of a Composite, even if you overrode all surfaces, surfaces of inside skins will still display with their surfaces coming from their Building Material definition. You can play around with the various Partial Structure Display options to see that.

has anyone else noticed that Delete + Replace is NOT an option in Attribute Manager? What a pain in the butt... Being able to select 50 fill types and hit delete+replace would be so much nicer than having to do it individually in the fill types dialog, which seems to be the only way to do it.

How does stuff like this slip through the cracks? Or am I missing something?

Yes, I notice, now that you say it.
Make a wish, it would be a great addition to the program.

Hello, everyone!
Hope it is the right topic to put the question - exported a file from AC15. Working on TEAMWORK allows no alterations with building materials. Reserved everything but the Delete button as well as other options stay grey, unavailable. No such prob in solo-mode.
I have like a million of them after changing versions and would like to clean up a part badly. What do I miss?
