Once you have started the Lofted Surface command, you can proceed as follows (please note that you can follow this step-by-step example by loading file: "UVcurve-02.e3").
As you can see, the curves in the above model identify two orthogonal sets of parallel curves (the red ones and the blue ones plus the border on the right side of the green surface).
Suggestion: to make curve selection easier, turn the viewing mode to Wireframe.
| 1 | To obtain an associative surface, that is an open solid — a Skin — retaining a link to its base curves, so that if you modify such curves the surface will be modified accordingly, check the Associative Mode box. See "
Associative Surfaces (Skins)" for details. |
|
| 2 | If not already selected, Select As drop-down list, select the
Grid option. |
|
| 3 | Select the red curves as the first set of curves (Boundary Set A — please note the selection order is completely free): |
|
| 4 | Select the blue curves and the border on the right side of the green surface as the second set of curves (Boundary Set B — the surface border is to be selected as the first or the last one; the selection order for the remaining curves is completely free): Once the border of the existing surface has been selected, the Continuity drop-down list is displayed, enabling you to choose positional, tangency or curvature continuity along the common border.  If you select Tangent, the resulting lofted surface will have tangency continuity along the common border with the green one.
