How to remove metal roof

[Anonymous]

We added a standing seam metal roof via the Extras/accessories/roof accessories/roof surfacer. At contract closing the client backed down and wanted the metal roof removed and a standard 3 tab shingle roof used instead. I can not seem to figure out a way to get rid of the metal roof. Any one have any ideas? Yes I know, simply make another roof, that was what I have done. In this case the roof was quite simple. If the roof was rather complex, that would not be a good option. I did a search and found no results for roof surfacer. I am hoping this is not a duplicate question.

You can use "Find & Select". Change the type to object, as that's what they become when you have done any thing under the extras menus, then you can choose by name. From the list of names you get you can simply choose the metal roof object hit the + button then it will be selected on your plan, then just delete it.

Note: make sure that you are on the right story, as find & select is story sensitive.

unless you're in the 3D window . . . where everything on view is selectable using 'find and select...'

you should also be able to pick up your roof surface by shift-selecting one of the nodes of the roof - just make sure that you have the object tool active first.

By Golly that worked! But then that leads me to another question. If I grab and drag the roof, the roof surfacer comes along with the roof. Sooo, that means that the surfacer and the roof are grouped, even though groups may be turned off. What other objects behave the same way, ie are automatically (and invisibly) grouped with some other object, and wouldn't it be nice to be able to automatically group other such related objects? I am probably clear as mud, Just thinking out loud.

nooo. they are grouped, but not in the usual way that we see in archiCAD:

there are several tools (usually 'add-ons' found in the extras/accessories menu) that operate on your existing elements to provide special additional functions: this happens at a higher level in the program than the normal user-defined grouping.

roof, wall and slab accessories take into account the attributes (eg length, height, material, shape, etc.) of the element that you are working on, and update themselves when you change the attributes of the original element.

you'd want your roof surface to change if you changed the shape of the roof wouldn't you?

btw - this kind of 'relationship' established between elements is, i believe, how revit operates: however, imagine if you have a large building, with all elements having defined relationships to each other. . . and then imagine the processing power required to keep track of everything when you maybe move one simple wall! it does have it's advantages, but at present, i'm happy creating these relationships myself, temporarily, with the marquee tool.

Just a minor point. The function would properly be described as occurring at a lower level. In programming parlance the lowest level is machine language (and hardware), the highest level is the user, and everything else is in between. For example Assembler is a low level language, C++ is a higher level, and Applescript and Visual Basic are higher still.

I agree with Ben and just want to put my semantic 'spin' on it.

The roof and accessory surface are not grouped, but are "associated". The wall accessories have similar behavior.

These objects automatically adapt themselves to changes in the geometry of their 'parent' object, the one with which they are associated. So, if you have a roof and insert a new skylight, the roofing accessory will get a hole in it. Ditto, moving windows and doors (or inserting/deleting) with respect to the wall accessories.

It is an invisible relationship (there are no colored circles or squares at the hotspots as in grouping) ... but as you saw, it does behave similarly to grouping in some ways.

There is no 'disassociate' operation, like there is an 'ungroup'. Instead, you have to delete the accessory object AFAIK.

HTH,
