Properties of a non-AutoCAD element

[jerzy.bajor]

I'm starting to use an Autocad overlay that has its own (non-Autocad) elements.
I tried '(vla-get-NumberOfBars...)' but it didn't help. An error occurred, which was to be expected.

 

I can view the properties of this element, but I can no longer download them for further processing.
Is there any way to get to this data.
The 'aliens' here are definitely: NumbersOfBars, Position, Multiplier, Diameter, Distance. DistanceStr.

Does the (getpropertyvalue) function get it for you?  Read about it.

Or the other (vla) approach?

(vlax-get elem "NumberOfBars")

Unfortunately, the getpropertyvalue function does not allow you to obtain this value.
The properties window, on the other hand, allows you to change it, so there is some way to get in and change its value.

have you tried  vlax-get-property?

(vlax-get-property (vlax-ename->vla-object (car (entsel))) "NumberOfBars")

Is there a Forum somewhere for the overlay program you're using?  It seems like an overlay-program rather than an AutoCAD question.

Looks like a proxy object as suggested by Kent, can be hard or easy to get at.

It worked.
To access the data, you had to run any command from this overlay.
It happened by accident.
