Can this be done?2. If so, is there a simple way of doing this using scheme/C++?3. Is it possible to perform booleans on these models (given initially as meshes) without going through the process of making a solid.I am currently lost and any help will be highly appreciated.Thanks,SriRam-------------- next part --------------An HTML attachment was scrubbed...URL: http://lists.cs.columbia.edu/pipermail/acis-alliance/attachments/20040103/aa1862b7/attachment.htmFrom lxg at jlu.edu.cn  Tue Jan  6 10:05:25 2004From: lxg at jlu.edu.cn (Liu zhiguo)Date: Mon Jan  5 21:12:35 2004Subject: [Acis-alliance] How to use HealingMessage-ID: <7772C66A931.AAA2C12@mail.jlu.edu.cn>Hi everybody,  Who knows how to use healing of ACIS? I use acis R12 MFC. I have read the help on autoheal of acis, but api_hh_auto_heal does not work well when I use it in my MFC application. Who can tell me whether my step is right:1. Read SAT file2. combine all the faces to a single body3. initialize healing4. autoheal: api_hh_auto_heal(body)5. terminate healingDoes it right? Who has some samples of healing to share with me?

Any given edge can, and will, be used multipletimes for a closed solid.  For a simple, manifold solid, every edge will beused precisely twice, once with  ce->sense()==FORWARD, and once withce->sense()==REVERSED.  For a nonmanifold solid, an edge can be used morethan twice, with multiple cases each of FORWARD and REVERSED.  There are avariety of approaches to finding a list of edges, each occurring once:0.  There may be an api function for collecting edges.  Some such werewritten at some time in the past.  My habits were ingrained long before suchwere written.  If such api function exists, it would rely on functionalitylisted below.  If you don't care how it works, seek the api function.  Idon't know whether it exists or what it's called, again due to historicalreasons.1.  Each EDGE has a coedge() member.  If the edge backpointers are correctlyset, you can ask if(ce->edge()->coedge()==ce) to determine whether thisreference to the EDGE is the unique reference to edge you are looking for(as long as the coedge_ptr member of EDGE doesn't change).2.  Each EDGE can be labelled with an attribute as you visit it.  As youcome upon each EDGE, you check for the presence of your attribute, and ifit's not there, go ahead and do what you want to the EDGE, but make sureyou've attached an attribute before going on to the next EDGE.  I've writtencustom attributes, or used ACIS pre-defined attributes, for this purpose.This also works fine, but requires you to clean up afterward and usesmemory.  It does have the advantage that the edge->coedge pointers can bemodified on the fly, so permits you to do some graph surgery on the modelwhile you traverse it.3.  ENTITY_LIST has historically been a SET, not a LIST.  ENTITY_LIST.addshould only add the EDGE to the list if it's not already present -- youshould only be seeing the unique instances, without requiring any checkingof  (unless ENTITY_LIST has been changed in R12 in a way that I'm not awareof; I'm not completely up on R12 for all my apps yet).  I don't understandyour concern, unless ENTITY_LIST does something funny.I need some clarification on your complaint about EDGEs being "numbered manytimes".  Do you have multiple, distinct edges at a given geometric location,or do you have multiple copies of the same pointer showing up?Arlo Amesalames@sandia.gov-----Original Message-----From: liu zhiguo [mailto:lzguo@jlu.edu.cn]Sent: Friday, January 09, 2004 6:13 PMSubject: mail from Liu zhiguoDear Ames,  Thank you for your reply, I have found the error code in my healingprogram.
