hypermesh

[Joel]

Sorry if I fill the forum, but I'm trying to learn how to use hypermesh and venedo from catia world - solidworks I find myself a little in trouble. doing the tutorial, important a caty file, I made the corrections of the surfaces (before they were in red).
1- When the "lines" are green means that they are correct, that is, there are no overlapping problems or "strap"? .
2- the lines in yellow what they indicate, can I leave it so in general or the best case is to correct it by erasing it and remake the surface?
3- when I corrected the surfaces, as I repeat coming from catia, at least in caia there was tangence with the adjacent surface (for surface correction) which I do not see in hypermesh. I wanted to know how I understand that the adjoining surface is tangent?
4 - a difficulty that I found (even banal) is in the creation of elementary geometries such as point, lines and itsprphics. for hypermesh the point and knot are the same thing?, to create a line you have to go from the knot?. is it possible to create lines, knots or points in parametric form? (as with catia and solidworks)

Thank you again and I apologize for the number questions I have asked today.

I attach the geometry I have done in the tutorial.

Hello, Joel.
1.2: in hm conventions:
Red edge indicates that surfaces are not "tolerance". I mean, when you go to a mesh, it won't be connected. green edge = edge shared by 2 surfaces, yellow egde = edge shared by + of 2 surfaces (t connection), blue edge = edge suppressed. when you make mesh the knots will not generally align on the hege. cmq topological changes do not have the same meaning as the cad. when you make a green edge that was red, do not go to change the surface making it "tolerance". It's just a flag on the edge that indicates that the mesh you create on the two surfaces that share the edge must remain connected.
3. There is no change to the surfaces, as I said. when meshi then, the tangency no longer exists as there is a discretization. hypermesh is not a cad as a cad.
4. in hm you can find cad points (viewed as x) or temporary nodes displayed as yellow balls. in the created nodes panel and create points there is the possibility to create nodes and points in various ways. in the line panel you can create lines from knots, points or even in other ways.
