Using this command, you can create the surface by fitting the boundary in mesh data.

1.

Click Insert > Surface > Boundary Fit or click  on the toolbar.

2.

Select the curve to create the boundary fit.

3.

Click OK. Hide 3D Mesh Sketch.

·   Mesh Curves – You can specify the curve or 3D sketch to create the boundary fit.

·   Resolution – Resolution method to fit the mesh.

a) By Allowable Deviation - If this option is enabled, you can specify a tolerance value to create the surface from mesh. Tolerance is the allowable deviation.

Allowable Deviation – Fitting tolerance value when the Resolution method is By Tolerance.

Outlier Percentage For Allowable Deviation –Outlier may contain noise data in the mesh data so you can decide the percentage of outlier. Set the value in the Tolerance tab of Preference; File > Preference.

Maximum No. Of Control Point – In the range of deviation, XOR automatically creates surface with control points within the maximum number of control points.

Regularize Control Point Count Of Patch Network - If you check this option, XOR tries to make regular number of control points comparing with neighbor surfaces.

<Disable Option>            <Enable Option>

b) By No. of Control Points – If this option is enabled, you can select the
         number of control points to fit the region or mesh as surface.

No. Of U Control Points – You can specify the number of control points in U direction to fit the region.

No. Of V Control Points - You can specify the number of control points in V direction to fit the region.

Set Manually - You can manually input the number of U or V control points by selecting curve in the model view.

·   Smoothness – Smoothness of the surface.

<Smoothness: Less>             <Smoothness: More>

·   Resample Mesh – If this option is enabled, XOR creates regular iso line of surface. We recommend using this option except complicate shape of mesh inside the loops.

·   Tangent Constraint on Boundary – If this option is enabled, tangent constraint is applied to the boundary.

<Disable Option>                  <Enable Option>

·   Match Surface Globally – If this option is enabled, all created surfaces are matched after creation.

·   Continuity Type – Type of continuity. Position continuity means the position agreement with adjacent surface. Tangent continuity means the tangency agreement with adjacent surfaces. Thus, if you select Tangent option, the generated surface is smoothly connected with its adjacent surfaces.
 

·   Sew  Patches– If you check this option, XOR combines surfaces into one body. If you don check this option, XOR creates each surface body.

·   Use Mesh Normal to Evaluate Loop Winding – If this option is enabled, mesh normals are used to evaluate the loop winding.

<Enable Option >              <Disable Option>

·   Allow Hole(Boundary) – If this option is enabled, though there exists a hole in the mesh, surface is created.

<Enable Option >               <Disable Option>

·   Allowable Convex Ratio – Allowable convex or concave ratio to create surface between loop and inside shape of loop.

<Ratio: 10 ; possible to create surface>  <Ratio: 2 ; impossible to create surface>

·   Curve Loops – You can select or deselect loop when creating surface.
