Hopefully i can explain this accurately. When i am done creating a family with muultiple types, call them, type A,B, & C. If i change any of the values for any of the paramters in the property types window, the family behaives absolutly find.

The problem comes in if i change a parameter value, lets say for family type "B", within the "model space", so if i where to select a dimension w/ a parameter, and edit the parameter through this process, when i go back into my type properties menu, and change type to "A", or "C", all the parameters, for "'A's" & "B's" now inherits the types i changed in model space, or Type "B's"parameter values. So when i change type there is no difference in parameter values, as if i created a new type. Very frustrating to find out the hard way. So now i am very careful of not editing values within families through the families' model space.

Not sure if it is my version i am running, or if this is a known glitch, or if it's my local drive set up. I just work with the tools i got. Really just posting this in hopes it saves someone a little unnecassary frustration.

Any light shed on this would be greatly appreciated.

I don't understand either.  I'm not sure what you mean by "model space".  So if you have you familiy A, B and C and say you change the length of "A" are you saying it is automatically changing the length of B and C also?

Exactly, but only if i change the parameter via a view. If i change a parameter value via the type properties menu, all is well.

- Situation - 

-I have 3 family types. "Type A", "Type B", and "Type C".

-There "Length" parameter values are: "Type A"=10'-4", "Type B"=8'-2", and "Type C"=15'-10".

-There "Width" parameter values are: "Type A"=6'-1", "Type B"=2'-9", and "Type C"=12'-5".

- Starting from Scratch: I open the family file > Open the type properties menu > change first type from ,"Type A", to "Type B".  > Close the window > Select a dimension with a parameter assigned to it, " Length=8'-2" " (it turns blue) > I click the now blue dimension, and from here i can change it's value > I change it from 8'-2" to 11'-7". > If i go back into the Type Properties menu and change my family type from "Type B" to any of the other 2 types, "Type A", or "Type C". All the other parameter values change to match the parameters of "Type B". So all 3 types "Length" values are 8'-2", and all 3 types "Width" values are 2'-9".

----------------------------------------------------------------------------------------------------------------------------------

If i do this exact same thing, but direct from the type properties menu. There is no issue.

P.S. - I can send screen shots of one of my mechanical equipment if the above explanation isn't clear enough if either of you would like.

What are type parameters and what are instant?

Make sure you don't have similar named instant and type parameters in your family.

Can we see an image of your family parameters?

Instead of changing the dimension from the plan(elev/sect), just change it in the type properties.... what happens then when you switch type?

Yea i have been doing that way. That works fine. It's only when i cahnge there parameter value in a view. Here this family has 3 types in it. "LPAC-1" & "LPAC-2 should have the same values, but "LPAC-3" is overall larger and has different values. If you have open the type properties menu, and change type you can see the values chenge. Then with the "LPAC-3" active, click ok, and change one of the parameter values in a view. Then if you go back into the typr properties menu, and change to another type, you'll see the "LPAC-2" parameer values automactically changed to match "LPAC-3"'s.

I see what you see but I don't see that problem with other families.  Perhaps it's your file.  SWet to autodesk and ask them.
