Mass reading errors from .ork file

[sanketdiwale]

Hi Nathan,

I noticed a mismatch in the mass of the rocket and its components when reading a open rocket (.ork) file from the openrocketdoc interface and from OpenRocket-15.03.jar itself.

I have provided a minimal example below and attached the .ork file I was reading below.

Minimal Example

import openrocketdoc
from openrocketdoc import loaders
rocketloader = openrocketdoc.loaders.Openrocket()
rocket = rocketloader.load('StarterDesign.ork')
print("Rocket Mass:")
print(rocket.mass)

Example Output

Rocket Mass:
2.03641177398

Issue

If I open the file with the OpenRocket simulator version 15.03 that can be downloaded from
http://openrocket.sourceforge.net/download.html

I see that the mass of the rocket without motor is 2447 grams. Further if I check the mass of the nose cone component in open rocket it is 218 grams while in the openrocketdoc interface it is 0.

Question:

I was wondering if this is a bug or this is the expected behaviour. Further if I have components with overridden mass the loader does not see the overridden component mass either.

Is there some way by which I can get the correct component and rocket mass readings from the .ork file?

Thanks,
Sanket
