Re: [Question #707311]: How to add rotation on the Boxfactory?


Question #707311 on Yade changed:

Jan Stránský posted a new comment:
> When I run the code the terminal shows 'BoxFactory' object has no
attribute 'id'.

it is because BoxFactory has no attriute id..
You cannot use it like this.

> I think Boxfactory might not be able to rotate.

The factory is just a "meta" object, creating new particles according to given criteria.
You really cannot rotate factory itself..
You can however rotate the particles it creates. But not using BoxFactory itself directly.

First,powders are deposited in a facetBox with an opening at the bottom. Then the facetBox is given a RotationEngine and a TranslationEngine(oriented along the z-axis) to achieve the powder factory rotation effect.

Sorry, I missed it
Definitely it is feasible.
I just do not understand what you want to achieve..
What is "powder factory rotation effect"?
Why do you need a factory, and not just simply use predefined set of particles?
Do you want to rotate spheres, or facets?
... ?

> However, the engine and factory did not operate as set up

Most of the time the behavior is exactly as set up.
Maybe it just behaves differently then expected?

Then a valuable information for us would be the expected behavior
compared to actual behavior, which is still not clear from the messages
(see the questions above).
