Posted 24june, still floundering, hope for some guidance here please, I now have a tyre wall with fine raised number on it formed with a 1mm high raised edge round the numbers.
mesh is 12,566,203 and if I choose decimate, surely that will be 1,256,620 10% of the 12,566,203 but the number appearing in the box when choosing decimate is 300,000 and I have seen offered by default 200,000 I recall trying for 300,000 incase 200,000 was too low. so last value used gets offered again.
Just what number should we be using to retain the 1mm raised beaded edge to tyre wall numbers for example, or the thread on a 12mm diameter bolt on the vintage tyre hub ?
do we have to look at the face count and divide by 10 then use our number ?
I try for 10% and the result is bad. see attached image.
manual says decimate is for pdf and google earth so reading about now decimate mesh in youtube tutorials clearly is wrong for a requirement to get this into a CAD prog to reverse engineer.
However 12.5k will hardly rotate or zoom in photoscan on a dedicated CAD pc.
what percent is advisable to retain detail for export to CAD and surface/curve work such as Rhino3D ?
Also I have chosen high for mesh generation stage after choosing high for dense point cloud, mesh just reached 100% generation and now its decimating it, I dont recall that happening a few projects ago, is that normal ?
