Upon some further investigation, I have come to understand the method
a bit better
def PickObject(self,
obj=defaultNamedNotOptArg,
x=defaultNamedNotOptArg,
y=defaultNamedNotOptArg,
z=defaultNamedNotOptArg,
obj_num=defaultNamedNotOptArg,
entity_num=defaultNamedNotOptArg,
tolerance=9.9999997473787516e-06,
PType=0):
"""Retrieve an object ID and face or edge number by giving an object
type and global coordinates"""
return self._ApplyTypes_(76,
1,
(24, 0),
(
(16387, 3),
(12, 1),
(12, 1),
(12, 1),
(16387, 3),
(16387, 3),
(5, 49),
(3, 49)
),
u'PickObject',
None,
obj, x, y, z, obj_num, entity_num, tolerance, PType)
The tuple of tuples in the _ApplyTypes_ call is of flags for each obj,
x, y,...PType. For example,
(type, input_or_output_flag) = (16387, 3)
where 3 I believe indicates an input/output parameter. I can change
these to 1 (for input) and 2 (for output for obj_num and entity_num),
but it still does not work. I suspect there might have to be other
changes in order (obj_num and entity_num shouldn't
==defaultNamedNotOptArg, for example, and I am not sure if they should
be passed to _ApplyTypes_ at all).
I think this is the basis of the problem, but I still cannot solve it.
Nowhere else in my generated file can I find an example of this
working right to follow. I am really hoping to get this working.
Thanks,
Mike
