Point Cloud – Affordable Reverse Engineering Software

In this tutorial we will learn how to wrap a mesh around a concave point cloud.


Step 1: Start Point Cloud.

Step 2: Select Import Points from the Points menu

Step 3: The Point File dialog box is displayed. Browse for the file Wrap Mesh Sample 2.txt (typically located in C:\Program Files\SYCODE\Point Cloud\Samples\) and click Open from the Open dialog box.

Step 4: Select the format and delimiters in the Point File dialog box and click OK.

The points from Wrap Mesh Sample 2.txt are imported into the active 3DM file.

Step 5: Select Wrap Mesh from the Mesh menu.

Step 6: The Wrap Mesh Options dialog box is displayed. Choose Convex as the Point cloud type and click Ok.

A convex mesh is created as shown below. As you can see the inner points which make the point cloud concave are ignored. This is not what we want.

Step 7: Delete the mesh by clicking Delete Mesh from the Mesh menu.

Step 8: Repeat Steps 5 and 6. This time choose Concave as the Point cloud type and click Ok. A concave mesh is created.
