Description[edit | edit source]
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[edit | edit source]
- 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.
- Press the
- 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[edit | edit source]
- Change the DataOutput property to
Wireframeto create a Gordon grid. It uses the same frame curves but may have different numbers of curves in between.- DataSamples U and DataSamples 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.

A Gordon object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:
