Swept surface

Swept surface

Swept surface

(OP)
Hi everybody,

V5R14SP4

I´m trying to make a swept surface with a circular section, "center & 2 angles" option. Did it a million times in R12, but for some reason, it won´t do it in R14...

I´m trying to post a picture of the thing, I hope it works (never posted pictures before :(...)



As you can see in the picture, the "OK" and "Preview" buttons are unaccessible... unless I specify a radius value... What I was used to is to specify the center curve, the reference curve, possibly a spine (and the 2 curves automatically defined the local radius of each profile curve) and the 2 angles.

Actually what I´m trying to achieve is a circular-profiled surface (constant or variable radius) starting from a curve (the reference curve from the picture, an isoparametric curve of the blue surface) tangent to the supporting surface. I think this is mathematically completely defined, by making a 2D analogy: a circle starting from a point on a line, tangent to it (very easy achievable in a sketch). Years ago I worked in UG (v18) and the creation of such surface was possible. I always wondered why Catia couldn´t make it... So, the only workaround I could find was a 2-step scenario: I first build a linear-profiled swept surface normal to my reference surface, and then use its edges to build the circular-profiled sweep. Again, I´m not interested in a constant-radius surface.

Any tips on what the R14-options are? Or maybe there is a simpler solution to my problem?

Thanks in advance!

RE: Swept surface

Me again :)

I got half the problem solved (the big half, fortunately). For some reason, when trying to make the specified surface, the first access of the command gives the result as if the "Use fixed radius" option is checked, even if it´s obviously not... When I simply checked the option than unchecked it back, voilá! my old well-known surface...

If you have any suggestions on the "small half" (an easier way to get this kind of surface), any tip is more than welcome!

Regards,
Steli
