Tutorial #4 – workspace objects management
This tutorial applies to 3DF Zephyr 2.0 and higher.
This tutorial will use the dataset used in Tutorial #6, however feel free to use any dataset you like.
- Step 1 – introduction
Having multiple copies of the same object (or parts of them) within the same workspace is very useful: you might want to do different reconstructions with different settings for different areas of the point cloud / meshes.
3DF Zephyr comes with very easy to use tools for this purpose, namely the “New Object by Cut” and “New Object by Copy” tools.
- Step 2 – Making a copy of an existing object
|From the “Project” tab (1), simply right click the object you wish to duplicate (2) (point cloud or mesh) and left click “Make Copy” (3). A new object with the same name (with “copy” appended to its name) will appear in the workspace (4).
You can now use this newly created object in an independent way: for example, you can clean this point cloud and then feed Zephyr the new copy as input point cloud when generating a mesh, so you can always go back in case you realized you removed too many points.
Remember that these copies will increase the .zep filesize considerably.
- Step 2 – Making a copy from cut/paste
|Either select a subsection of your subject by clicking and dragging after selecting the “Point Selection Mode” (5) or by drawing a polygon using the “Polygon Selection Mode” (6). When finished, the select area will be highlighted in red (7) (remember you can use the “Invert Selection” tool (8) if you wish to do an inverse selection).
At this point, all you have to do to cut or paste your workspace object is to click the “New Object by copy” button (10) or the “New object by cut” Button (11).
New Object by Copy: will create a new object in the workspace by copying the selected area into the new object.
New Object by Cut: will split the currenty selected object – the selection will become the new object, will everything that hasn’t been selected will remain in the subject of origin.
- Final notes
Experiment a bit with these tools since they can be a great aid in your workflow.
