Tangent surfaces using offset surfaces

[palma]

Hi! How can I join the edges of surfaces so that when I use surface offsets, they remain tangent and do not separate?

[Gijs (Gijs de Zwart)]

hi @palma are the surfaces tangent to start with? Offsetsrf will not extend surfaces

[palma]

Yes, in the main model the edges of the surfaces are tangent, when I perform the surface offset, they separate…

[Gijs (Gijs de Zwart)]

Can you send the model?

@palma

Yes, in the main model the edges of the surfaces are tangent

I don’t see that here:

So I must first make the original surfaces tangent to each other and then perform the srf offset?

[Gijs (Gijs de Zwart)]

yes, otherwise, if there is a tangent difference, the surfaces are going to separate or intersect.
