Checking geometry type

[lecetar]

Hi all,

how can i check if a geometry is of a certain type (Brep, mesh, crv...)

I know how to do it vb.net,

VB Code:

...
if TypeOf obj is Mesh Then
...

but this is not working instead

Python Code:

if (obj.ObjectType == Rhino.DocObjects.ObjectType.Mesh):

The error is:

Runtime error (SyntaxErrorException): unexpected EOF while parsing
File "", line 31
if (obj.ObjectType == Rhino.DocObjects.ObjectType.Mesh):

^
SyntaxError: unexpected EOF while parsing


any help?

I'm not sure that this is the proper way of going about it, but it works for checking RhinoCommon object types:

Python Code:

import Rhino as rc
 
# x is the object to check
 
if type(x) == rc.Geometry.NurbsCurve:
    print "You've got a curve"
   
elif type(x) == rc.Geometry.Point3d:
    print "You've got a point"
 
# Etc. etc..

it works!

I was trying this too, but i didn´t write any statement inside "if" , this was the problem. Newbies...

thank you very much!!

Cool, glad it worked out. When using the colon at the end of if statements, functions etc. you always have to indent the next line and write some code. A good tip while building up the logic of your code is to use the pass statement which essentially does nothing, but means that you won't get an error in "empty" statements, functions etc.

I see... thanks again!
