Menu : SURFACE

Command: Design:Build

Shortcut : b

This command is an exact equivalent the command BUILDÞCreate Surface. The command is included in the SURFACE menu for consistency, so that all the surface creation commands are located in one menu.

The Build command creates a surface based on the projection and section curves contained within the target element. It is the most flexible surface creation tool available within DeskArtes. There are several different forms of the command, depending on the types of information the projection and section sets contain. This is explained in the ‘Typical Modeling Session’ section of this manual.

Building with 2D projection curves requires that there be at least one projection set containing one or two B-spline projection curves, and that the section set contains at least one section curve which may be either B-spline or Bézier. Further control of the surface creation is given by the other commands in the BUILD menu.

As a consequence of creating the surface, all previous surfaces and faceted models within the element will be assumed to be redundant and they will be deleted.

The interface to building with 3D curves is otherwise similar, except that the projection curve(s) may be either B-spline or Bézier, which should be placed in a 3D Projection curve set. Additionally, with 3D curves the system asks for the interpolation method when starting the command. Bézier interpolation generally guarantees closer following of the projection curve shapes, while the B-spline interpolation may sometimes produce smoother results.
