Hi there
I've tried searching for this topic in this forum, but I failed to find one, so here my post.
I open the MCP STL file (LH faceplate) using Fusion 360 and I realized the size in the model is huge than what to be printed. I.e. 2258 mm in length. So I did some calculation by finding the transformation factor by comparing the model size and the actual B737 MCP length and I got the magic number 10.3 as the transformation/scale factor. To my surprise, after having it 3D printed, all the buttons and switches I bought (religiously following the exact item as suggested in this site guide) fit very well.
Ok then, I thought I would just do the same for the rest of the 3D model STL. When I opened the LH backplate via Fusion 360, then scaled it down using the 10.3 factor as I did with LH faceplate, the measurement on some of the button and switches placement (hole) Fusion 360 seems to be deviated few mm which I believe the buttons and switches will sit loose in them.
So my question is:
1) Is the model (over) size in Fusion 360 normal and we have to scale down using some of the calculated scaling factor? Is this the intended workflow?
2) If this is the intended workflow, can I use the scale factor (i.e. 10.3) across all the STL models? or the scale factor is different based on different parts?
3) Am I doing something funny here or there is better solution for this that I am not aware of?
Thanks
Hmm maybeeeee it could Be in imperial not metric but I doubt it as you found the 10.3 scale factor and that’s not that the scale factor would be
