Hi, I just joined this forum after reading as many posts I could find on the subject. I wanted to ask a couple of questions.
I’m working on a city scale model on a mesh that I believe has been poorly generated. The mesh have many intersecting faces - most of them so small as to be invisible and I haven’t been able to find an automated command that can fix this. So I have resorted to manually fixing the issues.
Many of the intersecting faces are where a vertices is slightly removed from each other. I can mostly fix this by selecting the cluster of vertices and moving them a little to a point on any axis. Sometimes I have to redraw the intersecting faces to get rid of the intersecting faces. I find the intersecting faces by running a python script, although this does not work in all cases… It’s a long and tedious process that I might look in to outsourcing.
I have been trying with moving the model to origin to see if the coordinate precision thing has an effect - and it does resolve some. But since it is a city sized model (cut in to smaller pieces) some of the model is still quite far from origin after relocation.
The model is to be used to 3d print a large model of the city, so it needs to be water tight and a ‘good mesh’.
I am working on pretty old PC hardware and am looking in to upgrading to a new workstation. I am mainly looking at a Quadro P4000 as the main component to build a new machine around. I am mostly modeling and don’t consider rendering to be a priority.
Not fully understanding the terms of “double precision” and “ECC” (less important I gather) that are features of the P4000. How, if at all, does it relate to Rhino’s “double-precision floating-point numbers” and the vertex coordinates?
(Main question) Does it mean that the P4000 will somehow be able to more precisely calculate the vertex locations and as a result the model will end up with less intersecting faces?
Any other suggestions for fixing the issues I have described?
If the case is that the P4000 won’t have any impact on the model geometry and just up the display capabilities I will probably go for a P2000 instead unless you have any other recommendations.
Any inputs will be very welcome, since you can probably tell that I’m not really very familiar with these issues.
