Reset a parameter when it is changed

Hello! 

 

Is there any way to lock a parameter so that when eg. a room description is changed it automatically resets to default (nothing)?

 

Or is it possible to lock a parameter so that no one else can change it? 

 

Thanks,

Linnea

No. But they can be done via a project manual or a bim execution plan.

It is possible to lock a parameter - check this box - 

 

Capture.PNGOR type in the desired value under Formula - in this case, the dimension will stay locked at 60"

 

Capture.PNGOR

 

Control the values in multiple families using Global Parameters

No, that "Lock" does not lock the value of a parameter.

What the user wants to do is not possible. An approximation would be to set the value of a parameter equal to a formula, but the user can open the family and modify that, too.

... I have said before how amazing will be if we can get some kind of a password protected or similar thing to lock projects, families or anything inside REVIT.

Interesting question ... and answers from our experts.  My response would have been; "Depends", because I do lock parameters so that no one else can change it.   And, I use formula-driven parameters that evaluate a condition and return a value based on the condition being true or false.

Hi

There are multiple ways to use Parameter and trick is which parameter to use and

how to insert modified family without affecting those parameters.

 

1. Type Parameter - this can be fixed per types of particular family.

2. Instance parameter - these can be modified in the project...

 

after making changes, and while reloading the family... Revit gives two options.

1. First as shown, keeps the instance parameters unchanged.. and does not reset the entire family .

2. But the second option will reset the entire family with values of parameters shown in the family.

 

Always chose option 1, if there are minor changes.. and keep a track of nested families and their parameter

Ex

Main family 

( Type Parameter )  

a. Fixed 

b. Fixed + Locked

c. Can be a Calculated

( Instance Parameter )

a. Can be changed in the project

b. Calculated using two or more Type Parameters

 

and same applies to NESTED Families further down...

 

Best luck.

Can any of the solutions offered in this thread "lock a parameter so that when a Room Description is changed it automatically resets to default (nothing)"?

"Or is it possible to lock a parameter so that no one else can change it? "

 

for this, that parameter should be Type Parameter with actual value given and locked..

one more level up, one can have another type parameter connected to the original one..

 

Ex 

height = Height A

Height A = 700mm and ( Locked ) ( type parameter )

 

this way, first parameter cannot be changed that easily...

Best way is just to have a parameter name suggesting its a FIXED Value

ex: FIXED HEIGHT = 700mm.... and family name suggesting the same..

The answer to your question is "Depends". Plain and simple. Where is "Room Description" coming from? Besides, the OP used "Room Description" as an "e.g.". He's wondering about the overall concept. That's my takeaway.  The answer to his question -- as he worded it -- is: "IT DEPENDS".   It not a question that can be emphatically answered "Yes" or "No".  IMHO.

For system families (rooms, areas, walls, etc...) you cannot quite reset a parameter when another parameter changed, but you can use a key schedule to standardize the parameters values. For example, when you change a bedroom to a toilet, it automatically changes the finishes as defined by the key schedule.

For loadable families, you can follow other advices already been said. One can be better than another depends on different practices and workflows.
