Great. I didn't know whether or not you had that option.

Most exciting and interesting stage starts! creation of custom front spoiler, rear spoiler and rear diffuser, I talked with almost every person working on fiberglass, some of them stopped doing this, some of them don't have the workshop anymore, and most of them are doing only copies of existing parts, or stuff that they already have molds of. Finally I found found two different persons, one of them is doing old-school fiberglass stuff, but another guy is in the first stage of his startup, his idea is to scan a car, create 3d model of the custom part, than print it in pieces in ABS plastic, than put it together. Since I can do 3D modeling that is a very interesting option for me, I can tinker with the design in 3D software until i get it right, and then we will print it! so the scanning began!


Here is the link to little video of the process:

And a photo:




It didn't quite work out well because of the car paint being too refelctive, but it's enough for me to start working on the 3d models of the custom parts, in the meantime we will rescan the car using special powder to make the car mat during the scan.

I will be posting pics of 3D designs soon!

You're soon going to realize one very large challenge trying to design parts in CAD around a 3D scan.

The output of a 3D scan is a tessellated file, most often an stl format, which is nearly impossible to work with in all the major CAD programs (NX, Catia, Creo and Solidworks). When I say impossible I mean: sure you can see it on the screen, but good luck taking measurements, or doing real CAD design around it.

You can use the STL as a visual reference on-screen.

Then, you redraw the part using sketches, using guide curves, etc.

Adjust your parametric model so it approximately follows the STL reference.

Just work with natively-generated CAD features, and everything will be fine.

I export scanned file to .obj file, which is a mesh, after I import it in Blender which I am learning especially for this project (I could do it in 3ds Max which I know, but decided to start learning Blender) after teh designs will be done, it will be exported as 3d printing file.

Still waiting to do new scan of the car, but decided not to waste time and started do 3d mockups front is first, just finished rough nose outline!

Tiny bit more of a progress )))

Another update

next week i will have new 3d scan of the car and will be able to finish 3d modeling of the parts, so far is still do some mockups on the scan that I have, that's where am at right now

Still tinkering with very bad 3d scan that I have until I do a rescan, added louvers to quarter glass in style of Lamborghini Urraco, It solved the problem of quarter glass shape looking too modern. After adding colors, I realized that front spoiler is out of proportion with the car, will continue to try different shapes and sizes.
