Hallo, I recently started working with Revit Architecture 2010 (after being 6 years an ArchiCAD user). I still cannot understand whether Revit objects are parametric or not. Can I change doors' or windows' pamameters? And how? Can I pick up parameters from an object (door, window, wall et c) and appropriate them to a multitude of other objects of the same type (for instance - pick up a round window as model and make all my windowa round)? Thank you, S.

You need to spend some time learning about families and types. If a family was built with instance or type parameters then it is parametric ... for what ever those parameters control. It could be size, visibility, materials ... many things. Most doors are built with the size being type parameters. Usually, the family has several types built in so to change size, just click on the door and select another type. Otherwise, you will edit the type, creating & naming this new type and editing the type parameters that control its size. Read your help on families / types and parameters - these spend some time with tutorials. You will find that Revit is really easy.

That means I cannot change them by pulling on control points or something like that :-( Sad. Nor can I expand an object's properties to a group of objects directly.

There are two different parameter types.... Types and instance. Type parameters are fixed ...obviously - by "Type"... This is very usefull. Lets say you have 20 doors in your project that are all 6'8" and now you want them to be 7'-0". Just select all of that type and change them. Instance parameters are... one instance. These will have the grips you were looking for. Not good to have instance parameters for things like door sizes ... but maybe the hardware or finish of the door might be an instance parameter.

Hi there Sieger, welcome to Revit! Regarding control points, these can easily be set up when editing the family. Generally though, these are only used when the parameter is an on-the-fly variable. Were you to have controls like this on your door dimensions you'd get some very angry builders wondering why some architect monkey had not used standard sizes! Regarding making batch changes, you can set up schedules that list the doors in your project by level, by type, by size, or by any other category you want to sort them by. Then you can make massive batch changes in a few clicks! Once you've got the hang of manipulating schedules for batch changes, you find that having a button for doing this would be a step backwards. Hope you enjoy Revit, keep asking questions!

Thanx. You are very helpful. It's really all different from what I am accustomed at. Will keep on trying. :-)

Watch out.... it will grow on you! Clear your head of any other program you were doing and look for the Revit way. It really is a simple mindset. In the chatroom, we call it a headslap ... darn <headslap> that was too easy. Glad you are on-board.

I am still lost. Made interior walls 123 mm width, just because I didn't find out how to make the walls with the width I need. I need it to be 118 mm (13 mm gypsum walls with acoustic filling). Now I cannot change I single wall I make into a desired width! Help please!

Pick in the Wall, go to the Propertires (in 2010 you can select Type Properties directly) then go to Structure "Edit" and you can add more layers, change the Function of the layer and give them the thickness you want, just like in the images, don't forget FIRST DUPLICATE the WALL and give another name.....

I Hope and I Wish to LEARN more, and more, and more.... REVIT |

Thank you! I made it! Now I created a new family (duplicated 123 mm and edited it into 117) and tried to select all walls I want to change, except exterior ones. Filter offers me to exclude elevations and other types of objects, but cannot differenciate within walls (has no option to select walls with the specified width). Can it be done in anyway? Thank you so much! I really appreciate your help! S.

If you right click on the wall there is an option to 'select all instances'. This will only select objects that are the same.
