Hi guys and girls, I may be talking out of my back bottom, but I have a rather detailed scanned model that I want to edit but I suspect it is so heavy (presumably the rendering?) that it is incredibly slow even when I edit / create shapes outside of the group the heavy object is in. Can I reduce the complexity of how it it rendered on screen, or apply any other tricks to make it more workable? See screenshot. It’s my first import-from-a-scan-so-I-can-edit-by-subtraction-and-addition.
that reply was a fast as it was simple Dezmo! Thanks
This is an alternative, have a Reduce polygon count function as well, beside the import.
Thanks! When I reduce the polygons I assume this is destructive, irreversible, to the model? The objective is to import, edit and re-export for 3D print. This being a small model, app. 10cm long, I worry that reducing surfaces will therefore make the printed output very blocky and angular. Correct?
Yes. It will change your modell. You have to examine/try the “amount of reduction”.
Unfortunately SU does not deal fine with small faces, you better to scale up first and scale down after reduction.
yes that’s a good tip, let me try! thanks
…and does not reduce the polygons unless they are coo-planar…
which often occurs with imported models !
That can happen!
(But checking the picture in a first post, I guess small chance… I may be wrong.)
Simply smoothing the model will reduce the render load. If it doesn’t have to produce all those edges it doesn’t have to work so hard.
I agree with what Box says, plus turn off the profiles:
thanks guys - will play with all of those options and suggestions!
trying that right now but the indicated time to complete is at 2253 hours
Specially the “Erase Duplicate Faces” option will be very slow! Try unchecked that first…
Thanks again for your help @dezmo - I’m able to use the scans at least for sizing components I am designing to fit them. I do ideally want to be able to add and subtract basic shapes to/from these scans but they do not seem to be solid. How do I figure out what is needed to make them solid - I can let loose Cleanup on them but it just sits there and ends up non responsive.
so you did wait the 2253 hours !
No I had the scans decimated
