A few quick guides to get you started.
Rotating Scan for correct XYZ :
Once you scanned your item. It will most likely not be setting the correct when imported into your CAD software.
You can use this method to correctly potion your scan before importing into your CAD software.
Open The scan in a 3d slicer for 3d printing.
Here i am using Bambu Studio, but prusa slicer, cura, lychee slicer etc… will also work.
Again it will load in not sitting on the plane correctly.
Find the lay flat button Click it and the scan will have planes on it. These are the flat areas you can lay the scan on.
Click on of the bottom planes
Once clicked it will lay on that plane.
Step 2.1) Rotating the scan
Rotate your View to a top view and find the “rotate model tool”
Click the needed handle and drag it to rotate your scan into place.
Now your scan is set correctly.
Step 3) Optional
Reducing triangle count
This step is not always needed but can help speed up processing in your CAD software.
Right click on your model and then click “Simplify Model”
This windows will open. Here you can reduce it.
Top number is current count, bottom number is after the reduction.
Remember going to low will make the scan low poly
Go ahead and export that stl now.
Save it as a new Name or add Rotated_Reduce to the filename.
Now you can import that into your CAD software and it will be sitting correctly.
