Solution needed plz

Post by Kevin Rodden » Fri Jan 06, 2017 4:54 pm

Hi just wondering if anyone had any ideas how i would go about trying replicate a broken quadcopter frame.
I need to duplicate the exact shape in order for it to fit back onto the quadcopter and the only way i can think of is by tracing around the frame onto paper and then scanning it on to my computer.

I have tried something pretty similar to this in the past but was unsuccessful.

Is there any other way i can achieve this, any suggestions would be appreciated.
The only software programs i have to work with is RD Works and Aspire.

Thanks
Kev

With Aspire you should be able to model it, but it sounds like a job for a 3D printer? There are sites that will print your files I think. Gene

I'm not familiar with the capabilities of Aspire and you may reject this answer as you suggest the only software with which you have to work is RDWorks and Aspire, but consider the free program of Inkscape.

You can take your scanned image, import it into Inkscape and convert it to vector format. That capability is integrated into the software, allowing you to export it in almost any format, many of which directly import to RDWorks.

If you desire precise measurement, place a ruler (or two, three, more) in various locations of the scan. You can then compare the measured screen size to the known dimension on the rulers and adjust scale appropriately.

If your frame is flat, as would seem to be the case, perhaps you can scan the frame directly and not worry about tracing. If the copter frame is of appropriate shape, you may also be able re-create the entire shape from scratch using Inkscape or a free CAD program.

Thank you so much for the replies.
Never thought about scanning the frame directly onto the scanner.

Cheers

I have used an office photocopier in the past, save the output as a pdf as it doesn't appear to affect scale.

The important bits are the slots and holes, the profile is generally cosmetic.

I take an accurate measurement of the longest dimension, like the overall length of the frame and then use it to make sure the image hasn't scaled when importing.

Assuming the frame plate is CF or Fibreglass, then a CNC is your answer

Thanks for the reply Ian i’ve just tried a scanning the bottom frame and to be honest it involves a lot of work just to get it half decent.
Not really concerned too much about the shapes and hole because your right they are cosmetic.
I might even try and design a completely different frame.

Might be the easiest solution, make sure it's symmetrical, then use the same design for the top plate that will make sure all spacers will line up.

What frame is it and what material is it made from? Can you post your scan here?

It's a 250 quadcopter frame, not sure of the material carbon fiber look alike.
