Best method for scanning these?

Postby dklassen » Tue Oct 13, 2015 3:29 am

Have 4 I need to do. They will be painted a mat gray. Lay them flat? Stand them up? Thoughts?

How about a rod through the hole with a bushing or collar to keep the blade suspended in the desired position? A black rod will show less in the scan and remnants should be easy to remove with an editor. The rod could be angled slightly to provide better/different results than a vertical rod.

I've never had great luck with thin objects on flat surfaces. I'd try to suspend them in front of the camera.

The blades are proving to be a monster challenge being so thin and symmetrical. Like you said, they need to be standing straight up which poses another challenge. Keeping them perfectly still but able to rotate and not obstruct any views.

Monster challenge indeed, I am already excited to see results. Scanner hates tiny edges I do not have a tip for this one, I can just wish you a good luck.

Yep, had a heck of a time, especially trying to get things aligned properly. It just wasn't happening for me. I ended up scanning the top and bottoms which gave the engineer enough geometry to get his job done.

I've done blades before...here's a tip. Don't scan a thin object. Create a fixture that you scan along with the blade so you have something to register with at all times. Once it's all together, delete the fixture and you will just have your blade.

use a turntable and fix the blade with knead/plasticine on it. when you are done remove the knead/plasticine. fix the blade otherwise with the knead to get the missing part, where the knead has been before.
