Wrong direction of surface continuity

Pioneer

Hi,

 

My problem is this. I want to create a surface continuous with two other surfaces (in this case G1, but this happens often also for G2) but the direction is wrong. A picture tells a 1000 words, so please check it out. Smiley Happy

Thanks in advance for your assistance.

What type of surface are you using?

Can you supply the part file? Or at least the area you are surfacing?

Hi, unfortunately I cannot. But it happens with any surface type where you can choose continuity.

Are the surfaces you are connecting to TRIMMED surfaces , look at the UV direction using Xform to see if that is causing the issue

Unfortunately there is no control on the surface creation tool to fix this.

I know of one workaround: If you change the surface normal on one of the bodies then that solves the problem. There is a reverse normal feature that does this. After this both tangent directions will be aligned.

Part of the issue appears to be you're only using 2 inputs where 2 guides and 2 sections (or a mesh type surface) would assist with the alignment issue you're having. This isn't anything new - it's hard to create a quality surface given the 2 edges you're using without having additional supporting geometry to guide the surface into the expected position.

Here is a movie showing what I meant.

Exaxtly what I was looking for!

Thought about the UV direction, not about the other tool. Strange that they are different things...

Thanks!

Changed the UV with the UV Direction Tool, but it didn't help.

Face normal is like the material side, in or out.

The U and V parameter directions are defining the surface itself.

The two are not related. If they were then sewing sheets (which required normals to match) would have to change U and V directions (definition) of the surfaces.
