| Edit Boundaries command edits boundaries of mesh data. Several options in this command provide to regenerate enhanced boundaries.
|
How to use Edit Boundaries command
Click  button on the toolbar, or click Tools > Mesh Tools > Edit Boundaries.
|
|
| Select one or several boundaries. Change the method to Fit and Fitting Shape to Freeform in the Fit Options. You can see the green curve and as you adjust Fitting Accuracy in the More Options, the shape of green curve will be changed.

| Click OK button. |
Options in Detail
| l Smooth – The selected keen boundaries will be regenerated smoothly. You can decide the influence range of poly-faces using the Select N-Depth From Boundary option in the Smooth Options. The green region in the below image is N-Depth poly-faces from a boundary.
|
| l Shrink–The poly-faces around boundary will be removed. Generally, the region near the boundary of scanned data may contain more measurement errors. Therefore, it is a good idea to remove boundary portions before starting the registration or merging process. You can control the depth of poly-faces which will be removed using Select N-Depth From Boundary in the Shrink Options. It is an opposite function of Extend.
|
| l Fit – You can regenerate boundary with several shape; Auto, Circle, Slot, Rectangle Polygon and Freeform. You can control max distance between original boundary and regenerated boundary using Max. Distance in the Fit Options. You can also control tolerance using Allowable Tolerance in the Fit Options. If you click (Auto Estimate) button, the application compute the value automatically. The below images show the each result of Fitting Shape. |
| More Options – If you select Fit method, you can set some options like below;
Fitting Type – Fitted creates a shape by doing standard best-fit around boundary’ poly-vertices/poly-faces. If you select Min Boundary, a shape which is most distant to it along its negative normal direction will be created. If you select Max Boundary, a shape which is most distant to it along its positive normal direction will be created. If you select Hole, the software calculates the circle by first fitting a circle and then repeatedly calculating the circle inside the circle until an inscribed circle is achieved.
Remove Outlier – If you select None, no outlier remove option will be used. If you select N*Sigma, you need to input N value into the box on the right. The fitting will be done by excluding fitting data whose error is bigger than N times of the standard deviation. If you select Ratio, you need to input a ratio value into the box on the right. The fitting begins with sorting the fitting data according to the error. Then only the data fall into the ratio will be used in the fitting. If you select Absolute Distance, you need to input a distance value into the box on the right. The fitting will be done by excluding the fitting data outside of this distance. If you select Sampling Ratio, the fitting will be done using fitting data sampled according to the specified value. Use Only Effective Data – Effective data means sampled data and outlier removed data. If checked, only the effective data will be used in the fitting. Rounded Corner – This option is available when you select Auto, Rectangle or Polygon. If you check this option, the shape will have rounded corner.
No. Of Edges – This option is available when you select Auto or Polygon. It decides number of edges of a shape. <Number of edges; 3> <Number of edges; 5> |
| l Extend – The poly-faces around boundary will be extend. You can control the distance of poly-faces which will be extended using Length in the Extend Options. It is an opposite function of Shrink. |
| l Extrude – You can extrude a polygon boundary, so you can create a volume. There are three methods; Blind, Up To Plane and Custom. You also can create completely closed polygon volume with no boundaries by using an option; Capping.
a) Blind – You can specify a length of extrusion or move dynamically a blue arrow in the Working Window. You also can create completely closed polygon volume with no boundaries by using an option; Capping. b) Up To Plane – You can select a plane to define height and direction of extrusion. You can also specify a length by entering value or moving a blue arrow in the Working Window. c) Custom – You can define height and direction of extrusion using a manipulator. You can move red, green and blue arrows and each color means a direction of X, Y and Z. You also can rotate moving red, green and blue rings. |
