APM 2.5 CAD Model for Google Sketchup Users

3689557486?profile=originalG'day All,

I have been working on a new airframe over recent weeks and wanted to replace the rather abstract 66 x 35mm box used to represent the APM 2.5 board with something a little more detailed and accurate.  My search for an existing model found nothing I could use, so a few hours later this is what I came up with.

In line with the spirit of open source, I will be putting this up on the 3D Warehouse when I get a chance.  In the meantime, please feel free to download from the bottom of this post.

  • PreventerWind51 - I have invested a few hours into trying to convert to step file, but to no avail.  I actually did manage to import the APM model into FreeCAD by exporting an STL from Sketchup.  FreeCAD should be able to export as both .stp and .iges, but I can't seem to get a success export (perhaps someone else could have a go at it).  Below is a screengrab showing the model open in FreeCAD (unfortunately the textures are wrong, but the scale and proportions are spot on).

  • Quadzimodo, Would it be possible to get a .stp or .iges version of these files? That would interchange with more standard engineering programs.

  • Hi Guys,

    I have collected all the relevant pieces of the puzzle including the board art and components, however I still don't know exactly what the accurate board dimensions are at this point, so it remains incomplete (perhaps until I have a board to physically measure).  I will post it as soon as it is completed.

    In the meantime, for a range of other relevant models - visit this page.

  • David - Keen to assist, but I don't know how I can output in that format.  Would a COLLADA .dae file format version help you bridge the conversion gap?

  • Any chance on putting up a .stp version?  I'd like to put this in my Autodesk Inventor model of the Arducopter.

  • Andrew - I am not nearly as familiar with the PixHawk as the APM, so I am yet properly understand all the differences between the prototypes and the latest iteration.  I also hadn't yet joined the GitHub community and was not aware of the resources that exist here.  I have just now joined and downloaded V2.3 of the PX4FMU, which I think is what I should be working with. Wow, GitHub is very cool.

    I should have the board sorted in 24-hours or so.  The new case will take a little longer.

    What info do you need for pixhawk? The schematics and board files are here. I suspect the main thing you'd need is a couple of good photos. If I posted some close up photos would that be sufficient?

    Cheers, Tridge

  • Wow that would take me months to do not hours! I am impressed. I wouldn't even know how to begin making that is sketch up. Basic stuff is tough enough for me. Nice Job. 

  • T3

    Wonderful! I don't know what I would use it for but I'll get the model as an example of what to shoot for as I learn SketchUp.

  • Developer

    very nice!

    It would be nice to have accurate models of the Pixhawk too. I have some models of earlier prototype versions, but nothing up to date.
