Hey all ! So I’ve been using Rhino for quite a few years and usually chose between large and small objects when it cones to templates intuitively. I know it is about the tolerances, but, when is an object large enough to be considered a “large object” (is a care a large or small object? is large co…

The templates shipped and installed with Rhino are for convenience and are nothing special. The templates labeled “Large” have an absolute tolerance of 0.01 and 500 grid lines. The templates labeled “Small” have an absolute tolerance of 0.001 and 200 grid lines. The absolute tolerance should be at …

There are a lot of ways to look at tolerance. The smallest should be an order of magnitude smaller then you need to fabricate. That means a ring will be quite small, but a larger bridge or city block might be quite a bit further. A conservative, lazy rule of thumb is to only count on 8 significant …

I guess it is probably also important to note they surface fitting trimming and joins will use the current tolerance. While the majority of calculations will land within tolerance, some calculations may get close to the size of tolernace. And this tolernace is then saved in that trim/join. So, if t…

Set the tolerance at the beginning of a project as tight as may be needed. Relaxing the tolerance and keeping the larger tolerance during modeling should not cause problems. Tightening the tolerance during modeling, even back to a previously tolerance, may cause problems.
