Описание

The Curves GordonSurface tool spans a surface on a grid of guide curves and profile curves.

At least a frame of 2 guide curves and 2 profile curves is needed for a Gordon surface, additional curves in between allow for a more detailed control of its curvature.

A grid of 3 guides (yellow) and 4 profiles (purple) → A Gordon surface

Usage

Select the lines that define the grid of the surface in the appropriate order:
- Select the guide curves (first direction) from one edge via the intermediate curves to the other edge.
- Select the profile curves (second direction) again from one edge via the intermediate curves to the other edge.
There are several ways to invoke the tool:
- Press the Gordon surface button.
- Select the Surfaces → Gordon surface option from the menu.
A Gordon object is created.
Optionally edit the values in the Property View to choose a different output type and adjust the related properties (see Properties below).

Notes

Change the ДанныеOutput property to Wireframe to create a Gordon grid. It uses the same frame curves but may have different numbers of curves in between.
ДанныеSamples U and ДанныеSamples V properties determine the density of the grid in U and V direction accordingly.

Samples equal the number of segments between the frame curves, 3 and 5 in this example:

Gordon surface → Gordon grid, the same object with Output property set to Wireframe

The input curves of each group (guides and profiles) should touch all curves of the other group. In other words, they must form a grid or net pattern as shown here:

In general, the surface normal of the resulting Gordon surface will be determined by the direction of the profiles.
In this example, the surface on the left, the profiles were drawn from +Y to -Y and the resulting surface normal is +Z.

And on the right, the profiles are drawn from -Y to +Y, resulting in the surface normal oriented -Z.

Part Extrude can be used to create a solid from the surface.

PartDesign Pad can also create a solid from the surface. Dragging the surface into a Body creates a Base Feature that can then be padded.
