Changing Dimension Prefix (Dynamo/Python)

Developers
#1

Hi people,

i’ve been searching for a way of, some how, change a dimension prefix or sufix. There’s a topic that talk a bit about it in http://dynamobim.org/forums/topic/get-dimensions-value-replace-with-text/ and there’s another one that talk about override dimension values too http://dynamobim.org/forums/topic/override-dimension-values/ . Both used python code to edit a single dimension value only.

My question is if there’s a way to change all dimensions prefixs, something like collecting all elements by family type and change the prefix to all that instances.

Cheers!

Here’s a good post from Jeremy: http://thebuildingcoder.typepad.com/blog/2014/09/revit-2015-r2-ur4-and-dimension-prefix-suffix.html

Thank you for your awnser Konrad! I forgot to mention, that I’m totally ignorant in coding. As I understand in the link you posted, he wanted to collect dimensions suffix/prefix, not to change it for a defined text. Am I wrong?

I’m sending in attachmet the codes created by Jeremy (from the first link i’ve mentioned) that’s running but nothing seems to happenGet-dimension-Value1 (1).dyn (2.0 KB)
. The other one, created by Ben Osborn (in the second link i’ve mentioned) that is working fine but just for one single dimension.dim-texts-change.dyn (2.4 KB)

Is it possible to work to all elements of a dimension type?

Hi Joaquim,

Are you looking to override Dimension Text Values?

Hi Kulkul,

Yes, something like prefix or sufix. Your script seems very close of what i’m searching. How did you did it?

import clr
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument
TransactionManager.Instance.EnsureInTransaction(doc)

for i in UnwrapElement(IN[0]) : i.Prefix = IN[1]

TransactionManager.Instance.TransactionTaskDone()

OUT = IN[0]

Note: This doesn’t work if any of the dimensions have multiple segments.

Hi Vikram, thank you for your help!
It works pretty well. I tried it not for selected elements but catching all elements and it works fine.

Thank you a lot :slight_smile:

Add List.Create after SelectModelElement node. Next time please start new thread.

#17

Thank you so much @Kulkul it worked. One last question when I use the Select Model Elements I can’t select any instance. Do you know why?

#18

Crossing window selection. Right?

#19

Yes!
