Maybe 3Dcontent central
You can also try TurboSquid.... Never used them but can't hurt to look. There is a post from them yesterday or the day before, just type in TurboSquid and the link shoud pop up.
Wouldn't models to the more global IPC-7351 standard be better. I would like to see a set of such models available as an open source project, the problem is trying to get higher managment to ok this. I have now done complete sets of IPC-7351 for two places in the past, it is time consuming. I would also like to see the models in a open format, say parsolids.
The key here is to know how the PCB footprint was created. How it is oriented (horizontally or vertically) and where its 0,0 origin lies (Pin 1, center of component or elsewhere!). My recent experience in building PCB component models has led me to the conclusion that most of the models out there do not have the proper projection; PCBs are designed with the "top" of the board in view (looking down). However, that gets translated as being the front view in the 3D CAD tool. I have spent the past 3 months (& new to SW/CircuitWorks!) learning to build 3D models of all types of PCB components, both SMT and THT. The task will be much more simpler after all of our designers adopt the IPC-7351 standard and make their footprints consistent across the board! Perhaps with my being new to the software, I am missing something which will allow me to simply change the projection on any given model?
I have undertaken the task with the idea that the translation between PCB design and the 3D model should have very little if no further intervention in order to maintain the integrity of what was designed at the PCB level and what is modelled. This will ensure a more accurate 3D model of the assembled PCB for mechanical review.
Just thought I share that with y'all!
Surface mount components should have their 0,0 at the component centroid, as this is generally also the pick up point for pick and place assembly. Through hole component vary, some use the centroid some us pin 1 as the 0,0 (I prefer the latter).
I make extensive us of move/copy bodies in SW to get models to match the required 0,0, especially when I’ve downloaded a model from a component suppliers web site.
I hope you can get your PCB guys to adopt the IPC standards, they’d be daft not to. It cuts out a lot of ambiguity in the design cycle between PCB design, mechanical and production. The library viewers give all the required dimensions and footprints, documents such as “Electronic Component Zero Orientation for CAD Library Construction” cater for rotations. It is also not to hard to convert current libraries to full IPC spec, I have done it now at 2 places and the benefits far outway the time and effort.
The next thing I want to see is an open source 3D library based on the IPC-7351 libraries and footprint names, so we can just download the required footprint. When I’ve time and resources I hope to start one.
