Interactive Vector Trim

The interactive trimming tool allows the user to just click on sections of vectors they want to delete.

Watch this video to see this in action:

The program finds the closest intersections either side of the clicked portion of the vector and removes the piece of the vector between the intersections. Optionally, when the form for this command is closed, the program can rejoin all the remaining trimmed pieces automatically.

Without using this tool, to remove an overlapping section of a vector, the user would need to insert extra nodes into both vectors, manually delete the intermediate sections and then manually join the resulting pieces. These operations can be performed with a single click using this tool.

When the tool is selected the cursor changes into a 'closed' scissor shape. When the cursor is moved over a vector suitable for trimming the scissors 'open' to show you can click and trim.

If there are lots of vectors to trim then the left-click mouse button can be held down and then when the cursor is dragged and hovers over a vector then it will also trim the vectors. This can be much quicker than individually clicking spans.

Note

If you try to trim a group then the group will flash pink. This indicates that it cannot be trimmed unless it first has to be ungrouped

Rejoin Trimmed Sections

Allows the user to select whether the program will automatically try to rejoin trimmed vectors when the form is closed. For most simple cases like that shown above with the overlapping rings, this option can be left checked ✓. If you have an example where for instance many trimmed lines meet at the same point, you may want to uncheck this option and rejoin the vectors manually.

Usable In Both Views

This tool can be used in both the 2D and 3D View.

2D View offers a more direct way to view your vectors while the 3D view offers more flexibility to work with Vectors in 3D Designs and to make use of the Edit Boxes.

When in the 2D view, a number of the forms tools will be driven by options in the form only.

  • Middle - Move the vectors (Hold Alt and move the selected objects in one axis)
  • Middle - Click a second time to switch to Rotational center. Click and drag the Rotational Anchor to reposition the Rotational Center of the current selection.
  • Corner (White) - Scale the vectors proportionally (Hold Alt for scaling non-proportionally, Shift to scale around the centre)
  • Edges (White) - Scale the vector in one axis (Hold Shift for scaling proportionally)
  • Corner (Black) - Rotate the vectors (Hold Alt to Rotate in 15° increments) about the Rotation Center.

In the 3D view, there is an expanded number of handles to directly edit the vector within the view, without needing to use the creation form on the left.

In the 3D View, the Handles are:

  • Middle - Move the vectors (Hold Alt to Move the selected objects in one axis)
  • Middle - Click a second time to switch to Rotational center. Click and drag the Rotational Anchor to reposition the Rotational Center of the current selection.
  • Corner (White) - Scale the vectors proportionally (HoldAlt for scaling non-proportionally, orShift to scale around the centre)
  • Edges (Black) - Scale the vector in one axis (Hold Shift for scaling proportionally)
  • Rotation Arrow (Top Black) - Rotate the vectors (Hold Alt to rotate in 15° increments)
  • White circles are properties unique to this tool to allow direct mouse editing of values in the tool form from within the view.

When you select a Transform Handle, it will activate the appropriate Edit Box for that Handle.

If you need an exact value for a field while dragging it, release the mouse button and type in the desired value, followed by Enter to accept the new value.

When used in the 3D view, you will see the Trim cursor change to show open scissors at the point it's possible to trim with a Left Click in the same way as the 2D view. Additionally though you will also see the vector spans which will be deleted by completing this action highlighted Red;
