>Hi,

>After some searching i found the qtacishoopsrefapp.zip:

>I hoped that this is a good entry point for my work.
>I'm able to compile it and the HOOPs part is also working  (drawing spheres,

>But whenever i want to load a SAT file a new Window is opened but only with

>What i don't understand:
>I've searched in the whole project for a api_initialize_hoops_acis_bridge
>call but didn't find any. 
>>From what I've learned in the ACIS manual concerning the HOOPS-ACIS Bridge
>this initialization function has to be called.

>Furthermore there is a

>statement in the code but it doesn't seem to be reached.

>My question: is this reference app really able to load and show sat files?

>Hello acis-alliance:
>  I am wondering how to undergo the incremental faceting.when i use the function
>api_facet_unfaceted_entity or api_facet_unfaceted_entities to facet a body,it does not perform as expected. The faceter still faceting all the faces on a body other than those faces that have changed since they were last faceted.I think it should be some wrong with my program,so could you please kindly tell me how to use these two functions correctly?

>Hi,
>    I am working with acisR10sp9.I followed the managed history streams example given in the september 2004 archives.I am practising an example for parametric modelling in ACIS.I am able to roll back to previous state from current state using api_changed_state.But I am unable to change the state further.What I have done is created a solid block,frustum and subtracted frustum from solid block and then rolled back to frustum  state and deleted the old frustum and created new frustum.What I need is would like to roll forward to subtracted state and that frustum need to be changed after forward.Here below i am giving  the code.

Hello,everyone:
I want to know how to use "api_loft_coedges",who can give me a C++ example?
Thank you!
