# "None" option in the Boundary Surface

What direction will NONE take?

I assumed that it will take shorted possible distance between profiles.

Attach your *.sldprt file here and end all doubt.

I recommend spending a bit more time in formulating thread title as well.

A good title helps in future searches by beginners researching existing information.

I would expect to see the term "Boundary Surface" in the thread title.

• ###### Re: None option in the drop down menu

This is a question always arise after seeing many works in the YouTube. I do not have any particular file at moment.

• ###### Re: None
Tangent Type Select one of the following: Default (Available when you have a minimum of three curves in the direction.) Approximates a parabola scribed between the first and last profiles. See Start/End Constraints in the Loft PropertyManager. The tangency from this parabola drives the lofted surface, which results in a more predictable and natural lofted surface when matching conditions are not specified. None No tangency constraint (zero curvature) is applied. Normal to Profile (Available when the curves are not attaching a boundary feature to existing geometry.) Applies a tangency constraint normal to the curve. Set the Draft angle and Tangent influence (%). Direction Vector Applies a tangency constraint based on a selected entity used as a direction vector. Select a Direction Vector , then set the Draft angle and Tangent influence (%). Tangency to Face (Available when attaching a boundary feature to existing geometry.) Makes the adjacent faces tangent at the selected curve. Set the Tangent influence (%). Curvature to Face (Available when attaching a boundary feature to existing geometry.) Applies a smooth, visually appealing curvature continuous surface at the selected curve. Set the Tangent influence (%).

None

Direction Vector

Tangency to Face

Curvature to Face

Obviously NONE is negating “Tangency to Face” option. Other two potions are in question. “Direction Vector” option can be ignored as it is for a particular situation. But nothing mentiond about the “Curvature to Face” option.

• ###### Re: None

Curvature to Face is for a curvature continuous face when attaching a boundary feature to existing geometry.

You can tweak the percentage of tangent influence to further "shape" it.

• ###### Re: None

When tweaking the percentage of tangent influence is there any chance to come across “Tangency to Face” option?
