Reference Callout - Get Boundary Curves

Developers
1

Hi,

I’m trying to get the boudnary curves of a reference callout.
Usually it is easy with regular view using View.GetCropBoxCurves. The problem with the reference callout is that it is not an actual view - it is just a reference but still it has boudnary curves. One possible approach is what @Dimitar_Venkov suggested for callouts - Objects in Callouts. This works - but the problem is that the bounding box is including also the callout head - image which is not quite right.

I searched for Revit API Method and found this - http://www.revitapidocs.com/2017.1/248f20e0-9735-5733-2c8a-6b871bb17d3b.htm
But I’m not experienced enough for using this with Python. Hope someone can help me with this and sucsessfully to get the curves of reference callout

The only way to get this information is with Python. I recommend trying to use the API method you found. It’s definitely worth getting yourself familiar with Python.

Yes, I know that learning Python will be good investment =) I already know the basics but some methods are difficult.
Tomorrow I will share my progress and what errors I get. Hope someone will give me a clue how to fix the script.
Cheers!

Hi There,
I managed to implement the API method and make the Python Script

I also used the code inside View.GetCropBoxCurves node from MEPover package.
Thanks!

Exactly what I was looking for! Thanks

i try to make a callout from the outline of some scope boxes i Create the views that i need for the callout and i just want to make a call out refer to the views that i Created

any help
thanks

Please share the code inside the Python Script node. It seems that you didn’t define the “uiapp” variable.

import clr
clr.AddReference(‘RevitAPI’)

#The inputs to this node will be stored as a list in the IN variables.
if isinstance(IN[0], list):

else:

toggle = 1

listout =

regions=View.GetCropRegionShapeManagerForReferenceCallout
(doc,x.Id).GetCropShape()
if len(regions) > 0:
lines = [t.ToProtoType() for y in regions[0]]
listout.append(lines)
else:
listout.append()

#Assign your output to the OUT variable.
if toggle == 0:
OUT = listout
else:
OUT = lines

You could use this method - https://www.revitapidocs.com/2015/f4eda97d-14a0-c657-c916-83da00add998.htm . But you will need to adopt it using Python.
You need different creation process. Because the referencing can’t be done after the callout is created.

thanks @ Petar_Penchev1 for your replay and your time but i can use dynamo node only i didn’t know python :frowning:

Sorry about that, you may search for Dynamo node which somebody already created - but there is no such a node as far as I know. I recommend you to start exploring different options for learning Python = ) There are a lot of online recourses - for example - https://learndynamo.com/ . It is good starting point. Good luck!
