Hello everyone!
That's the strange issue I've got: I've created a new furniture family importing a .dwg file in a .rft. Once my table was succesfully opened, positioned and scaled, I assigned materials to layers by object style window, paying attention to scaling textures according to object's part dimensions.
Then, I saved my new family and I loaded in my projects.
Well, within two different projects, I've got two different texture behaviours. The texture scaling is different from one to the other...
The materials I used are not shared, but created from zero.
What's happening? What I forgot to do? What I made wrong?
Thanks for reading

You say you assigned the materials in the family?

Yes, I did so.
It is an object created with 3D Studio Max and than imported in Revit.

This may be your problem....
Always remember that the project rules. If a material exists in a project at any time before the family is loaded, the material definition in the project governs.
A problem that often happens is a family is loaded then the family is modified and the material is altered in the family and the family is re-loaded. Guess what - there is no change in the project environment because the material exists from the first load.

Uhm!
There isn't a way to "purge" the project from everything related to a deleted element?

You have to delete the object and remove the materials. That can be a problem if the materials are used elsewhere. For special items, don't use a common name and test in a project where you can simply load/place then undo if not right.

After experiencing this issue within my main project, I was already "checking" my new objects in a blank projetct, as you are suggesting. That's how I noticed that no modification was updated reloading the family, although the changes at the family were saved.
Now I understand that the only way to "purge" Revit from unused materials is to manually delete them, one by one. Isn't it? Even if created and used only for an already deleted item/object/family.
Well, WWHub I thank you so much.

uhm... bad issue!
That's what I do:
1. purge my project from a certain object;
2. clear all the materials associated to this object from the project's materials library;
3. save and close the project;
4. open and modify the object from the family editor;
5. save and close;
6. reopen the project and reload the object just modified;
7. no changes from the previous version of the object.............. !!!
There is a way to figure it out?
P.S.
If I load the same modified object in a new blank project, it is ok.

P.P.S.
The materials implicated are use exclusive for this object.

unnbe
Your own test of using a new project has proven that somewhere you failed to get rid of the material and or the object.
Just deleting the object doesn't get rid of it. Instead, delete it from the project family browser. Then remove the material. Then duble check everything.

I solved!
Once the project is purged from the unused object and related materials are deleted, given that the object had materials assigned in the family (from Object Styles>Imported Objects, layer by layer...), remaining in the project, it is necessary to go in Manage>Object Styles>Imported Objects and delete the category implicated.

Great !
Learning by digging on your own really teaches you a lot and your posting what you found will help others.
Thanks
