Reverse Engineering

Hello friends,
Currently i am working on Reverse Engineering projects. And i'm a Design Freelancer.
Struggling a lot while converting CLOUD DATA to SOLID MODEL. Using Geomagic plugins in Solidworks, Need some video tutorials for point cloud data to solid model and sample cloud points data. Please help me???

If anyone have idea please share it here. This must be very useful for others also.

Hi,

I convert files from STL to STEP quite frequently. It is not all that easy yet, sadly. I hear about SolidEdge ST10 as an amazing software for Reverse Engineering.

All those apart, I do the following way:
1. Reduce STL resolution to ensure the file size is as minimal as possible without losing the details. See my attached files with details at 0.01. Your file is 50MB and mine is 2MB!! Already a huge step forward.

2. Reduce polygon count to further reduce the size of the file. But this is tricky as you may lose lot of details. So play around to get a safe polygon count.

3. Import the file in FreeCAD and convert to STEP or IGES.

Hope that helps.

Hi

I work at a company that our core work is reverse engineering.
We use Creaform VX Model to reverse engineer parts.
It's very simple to learn work seamlessly with Solidworks too.
We had previously used Autodesk Powershape but that was over complicated.

What is the end goal of the reverse engineering task?
Are you looking to recreate it in Solidworks with a full feature tree, and nice clean geometry ready to be sent out for tooling?

I've never use the Geomagic plugin, but I used Control and Design X. Design X was sort of handy as it would export data and rebuild it in SolidWorks, but trying to make models in Design X was not much fun.

At the most basic level, you are essentially going to be recreating the CAD data for this item feature by feature. Your only advantage is that you'll have the underlying mesh data to use as a reference for size and shape.

Before doing anything else, the model should be aligned with a coordinate system so you'll be able to work with standard reference planes, and make use of common relationships like vertical, and symmetry/mirror tools.
