Isdx surfaces tangency

Hi,

Didn't used isdx for few months.

Now on Creo2.

Within Isdx, when I'm creating a surface (made of 4 curves), sometimes tangencies are displayed but often not (little arrows).

I'm understanding that tangency is not always possible however I would like Creo to display little dotted arrow even when there are no tangencies.

Sometimes, it was possible to force it (then software asked to update boundaries constrains).

However, my question is just why those arrows are not displayed anymore.

Thanks,

You need to add the side curves (1 & 3 in you image) to the Primary curves to define the surface with 4 curves and leave the middle curve (#2) in the Cross curves.  Style works a bit different from Boundary Blend.


There is always more to learn in Creo.

Could you post a part of your model?

This is a sample of my problem.

3 vertical curves are normal with an horizontal plane and are tangent with the other surface.

However, I should see arrows, even dotted.

Can't undersand what's the problem...

Make sure you are connecting the new surface to a surface edge of another surface, not to a curve.
