By adding mesh curves to a surface, you can reduce the surface area that is modified when you reposition a mesh node.
By removing mesh curves from a surface, you can increase the surface area that is modified when you reposition a mesh node.
To add mesh curves to a surface mesh,
1. Activate the Surfacing module.
a. Click File > Modules. The Modules dialog box opens.
b. On the Modules pane, click Surfacing under Licensed.
2. Click Surfacing and then, in the Advanced Surfacing group, click Modify Surface. The Modify Surface dialog box opens.
3. Specify the face you want to modify by adding a curve to the mesh. A preview of the selected face is displayed, together with the surface mesh.
4. Click Add Curve.
5. Add curves to the mesh using one of the following methods:
a. Click a point on a mesh curve; Creo Elements/Direct Modeling adds the missing isoparametric curve that corresponds to the existing curve.
b. Click an arbitrary point on the face that lies in the interstices of the mesh rather than on a mesh curve (see 1 in Figure). Creo Elements/Direct Modeling adds two isoparametric curves in the U and V axes of the surface (see lines 2 and 3 in Figure).
6. You can now either continue to add mesh curves, manipulate the nodes of the mesh, or click to complete the operation.
To remove curves from a surface mesh,
1. Activate the Surfacing module.
a. Click File > Modules. The Modules dialog box opens.
b. On the Modules pane, click Surfacing under Licensed.
2. Click Surfacing and then, in the Advanced Surfacing group, click Modify Surface. The Modify Surface dialog box opens.
3. Select the face you want to modify. A preview of the selected face is displayed, together with the surface mesh.
4. Click Del Curve.
5. Click the curve that you want to remove from the mesh, for example, see point 1 in Figure. Creo Elements/Direct Modeling deletes the specified mesh curve.
6. You can now either continue to remove curves, manipulate the nodes of the mesh, or click to complete the operation.
