A lot of beginners in the realm of Alias tend to get enslaved to the boundary continuity locators,
and will enforce continuity along all edges when building surfaces. Hoping to see those locators turn green. And when they do, your surfaces have a good flow… don’t they?
Well they don’t. Necessarily.
Just like putting tangent fillets on every sharp edge and calling it a day, asking for curvature does not make the surfaces smooth either, it is a false sense of trust in the software. The software can not know what the surface to be aligned to the other surface is doing beyond the boundary.
The boundary is an artifact of surfacing, it can cause seams in our surfaces and we can’t have that. But it is not something magical, continuity at the boundaries is necessary but certainly not the whole story.
This is a cross section with curvature combs of an a-pillar blend, notice the green locator for G2, but still the transition is not smooth.
You will want to have the general flow of the two surfaces along their entire length have a matching character first,
and worry about the specific tolerances at the boundary (i.e. tangent 0.05, curvature 0.1) later.
You may notice a visible seam across your surfaces,
and you may think to yourself it is horrible! but we know from the curvature comb cross section that we are 95% of the way home.
Now is the time to put on that boundary locator, and dial in to those very tight industry tolerances.
It makes no sense to do this at any earlier stage than right at the end, because who cares if it is tangent and curvature to within industry tolerances… if the general flow is not good? it would be just a waste of time.
The result should look this this and it was, truthfully, less frustrating than just using boundary locators because we get (from the combs) more insight into our surfaces, which in turn yields a more intelligent means of achieving continuity and a smooth surface-set!
The Above Xsect is demonstrating that the modeler has the entire width of the surfaces under control
This is the level you need for an Automotive Entry level job and the best place to learn it is right here on line at LearningAlias.co.uk I personally have now made it into the Elite Student group, which has 100% success rate for finding Automotive Modeling jobs. LearningAlias feeds these students into OEM’s where they will start their career in a very supportive environment
Have fun surfacing!
