| 20:25.43 | kanzure | was step-g ever tested with .step files? |
| 20:25.50 | kanzure | and if so, where are those? |
| 20:26.42 | kanzure | i've tried it with a few files generated by lolcad and a few from opencascade (for instance, heekscad) and neither work (granted, lolcad was based off of OCC's understanding of STEP, but the errors according to step-g are different between lolcad/heekscad-generated-files) |
| 20:27.02 | kanzure | i'll do a full error/bug report once i figure out what's going on.. |
| 20:28.46 | kanzure | it's entirely possible that opencascade's understanding of STEP is completely, utterly flawed but it seems to be able to read in solidworks-generated .step files (although i forget whether or not solidworks can read in occ-generated .step files) |
| 20:30.12 | starseeker | kanzure: other possibilities - the step files don't contain solid geometry, our parser is missing something... |
| 20:33.13 | kanzure | both lolcad/heekscad .step files represent the same thing (a sphere) (although the ways they do it might be slightly different) and heekscad can load/render both |
| 20:33.32 | kanzure | the brlcad step parser is just NIST SCL so that's why i'm sorta surprised this doesn't work |
| 20:33.44 | kanzure | (and why i'm suspecting OCC's implementation of being at fault rather than NIST's) |
| 20:33.54 | starseeker | kanzure: add the two files when you file the bug report so we can try 'em out |
| 20:34.00 | kanzure | nods |
| 20:34.14 | starseeker | the NIST stuff is... quirky |
| 20:34.47 | starseeker | remember, it wasn't production code until we started working with it - it was the original NIST example tarball with some fixes from various folk |
| 20:35.02 | kanzure | for the heekscad/occ .step file: "ERROR: instance #32 'PRODUCT_TYPE': Unknown ENTITY type. / Data lost: (part,$,(#7))" and then it complains "ON_Brep has no edges. / m_object_table[0].m_object->IsValid() = false. / ON_Brep has no edges." |
| 20:35.10 | kanzure | the ON_Brep is openNURBS stuff, of course |
| 20:35.43 | kanzure | since it says "Data lost: " i am suspecting that SCL is just ignoring the PRODUCT_TYPE entity so maybe the only thing really failing is openNURBS |
| 20:37.02 | starseeker | from that error, my guess is the step NURBS entity probably doesn't have edges, or has implicit edges - for openNURBS (which is more finicky) we'd probably have to generate the edge |
| 20:37.35 | kanzure | heekscad/opencascade .step: http://diyhpl.us/~bryan/irc/sphere.heekscad.step |
| 20:37.47 | kanzure | lolcad .step: http://diyhpl.us/~bryan/irc/sphere.lolcad.step |

| 20:40.32 | kanzure | step-g output for lolcad .step: http://diyhpl.us/~bryan/irc/sphere.lolcad.step.step-g.log |
| 20:41.35 | starseeker | kanzure: yeah, the heekscad one looks like an issue going from step NURBS to openNURBS - that'll take some digging |
| 20:41.52 | starseeker | it's not "in context" for me at the moment |
| 20:41.53 | kanzure | the errors for the lolcad one are a bit more involved of course.. but heekscad/occ loads the same file just fine |
| 20:42.02 | kanzure | what? not in context? |
| 20:42.11 | kanzure | oh you probably mean you haven't been working on the NURBS stuff |
| 20:42.18 | starseeker | right |
| 20:42.29 | starseeker | I'm pretty deep into CMake at the moment |
| 20:42.36 | kanzure | yeah totally not expecting that of anyone ;) |

| 20:43.11 | kanzure | i guess since it's openNURBS that is crapping out, my original question ("is this valid .step according to SCL") has been answered |
| 20:43.22 | kanzure | but "sphere.lolcad.step.step-g.log" suggests the answer is no |
| 20:43.37 | kanzure | (heekscad/occ loads the lolcad-generated .step file just fine) |
| 20:43.58 | starseeker | right - the top errors look like errors reading the step syntax, and the openNURBS errors are going from step NURBS to openNURBS formats |
| 20:44.32 | starseeker | however, notice that step-g DID get as far as trying to create the geometry, which suggests that errors or not it got something |
| 20:44.45 | starseeker | heekscad/occ may just be quietly ignoring the errors |
| 20:45.13 | kanzure | i have a --debug or whatever compiled opencascade although i can't vouch for the validity of the config option |
| 20:45.52 | kanzure | i think to resolve this question i need a third implementation of STEP? |
| 20:46.07 | kanzure | or should i just assume SCL is good enough to be a reference |
| 20:48.01 | starseeker | kanzure: my approach would be to check the source of the complaining step file and compare it against the SCL error reports, see if they look legit |
| 20:48.34 | starseeker | growls at ISO - doggone it, why do they have to keep the STEP spec behind a paywall... |
| 20:49.02 | kanzure | i have various files that define the spec if you want.. christopher said he had something too |
| 20:49.23 | kanzure | as it turns out, nist.gov hosted the ISO spec for a while and then took it down but not before the internet archive crawled it :D |
| 20:49.37 | kanzure | http://web.archive.org/web/20030216045110/www.nist.gov/sc4/step/parts/ |
| 20:58.11 | IriX64 | can i ask if the CMakelists.txt effort is complete when we see a CMakelists.txt file in the root of the brlcad source tree? |
| 20:59.29 | starseeker | IriX64: the work is going on in the cmake branch for now - it's got a ways to go before it's ready for prime time |
| 20:59.48 | IriX64 | thankyou |
| 21:00.00 | kanzure | in sphere.lolcad.step i think "GLOBAL_UNIT_ASSIGNED_CONTEXT" should have another layer of parenthesis around its parameters |
| 21:00.04 | kanzure | but i'm not sure why |
| 21:00.24 | kanzure | and 1997. should be 1997 |
| 21:09.18 | kanzure | ah and next to "GLOBAL_UNIT.." the "3." should be "3" apparently |
| 21:10.58 | kanzure | this suggests that SCL is simply more strict in its parsing, then |
| 21:11.08 | kanzure | so that's encouraging |
