I have a model that has some text embossed into it. I need to remove them. (We're still making it in the USA, but it is not legible when 3D printed.) Unfortunately this file was exported from something else and appears to be 100% triangles. What's the best way to do this?
This model is very complex and curvy on both sides. It makes things like disabling "Limit selection to visible" not useful because there is no perspective where all of the inset faces are visible.
