Editing Data

From KScan3D

KScan3D provides basic mesh editing capabilities to help you achieve and export quality results. After capturing a mesh or point cloud, you can delete points to help clean up your scan data and improve processing speed. You can also smooth, erode, and decimate meshes.

Deleting Points

To delete points in a mesh(es) or point cloud(s):

  1. In the Thumbnail panel, load the mesh(es) and/or point cloud(s) you wish to edit. The data will become visible in the 3D viewport.
  2. Ensure that the data you wish you edit is unlocked. Locked meshes and point clouds cannot be edited.
  3. Press and hold the CTRL key, then click and drag while pressing the left mouse button to draw a lasso around the points you wish to select. Release the mouse button and the selected points will become highlighted.
  4. To add more points to the selection, press and hold the SHIFT and CTRL keys, then click and drag while pressing the left mouse button.
  5. Right-click within the 3D viewport to display the right-click pop-up menu.

  6. Select Delete Points.


You can also invert a selection of points by selecting Invert Selection in the right-click pop-up menu.


Smoothing a Mesh

The Smooth function applies the specified number of smoothing passes to the selected meshes. Each pass smooths a mesh by averaging the angles between individual polygons.

Note that point clouds and combined scans are not supported. Point clouds must be processed into meshes and combined meshes must be uncombined before they can be smoothed.


To smooth a mesh(es):

  1. In the Thumbnail panel, load and select the mesh(es) you wish to smooth.
  2. In Mesh Editor mode, select the number of smoothing passes you wish to apply in the Operations panel on the left side of the screen.

  3. Select the Smooth button to process the mesh(es).


Eroding a Mesh

The Erode function applies the specified number of erosion passes to the selected meshes. Each erosion pass removes one polygon strip from all edges in the mesh. Erosion will also cause all existing holes to grow larger.

Note that point clouds and combined scans are not supported. Point clouds must be processed into meshes and combined meshes must be uncombined before they can be eroded.


To erode a mesh(es):

  1. In the Thumbnail panel, load and select the mesh(es) you wish to erode.
  2. In Mesh Editor mode, select the number of erosion passes you wish to apply in the Operations panel on the left side of the screen.

  3. Select the Erode button to process the mesh(es).


Decimating a Mesh

The Decimation function allows you to decimate selected meshes. Decimation simplifies the mesh by reducing the number of vertices and faces used in the surface while preserving the overall shape of the mesh.

Note that point clouds and combined scans are not supported. Point clouds must be processed into meshes and combined meshes must be uncombined before they can be decimated.


To decimate a mesh(es):

  1. In the Thumbnail panel, load and select the mesh(es) you wish to decimate.
  2. In Mesh Editor mode, in the Decimation panel on the left side of the screen, select the target number of vertices and/or drag the slider to select a decimation percentage.

  3. Select the Decimate button to process the mesh(es).
