Settings
Display
Cursor
The cursor provides a real-time X Y position of the screen area; this is shown in the bottom right hand corner of the screen.
The following options are available within this section.
Cursor Positions
Off
This switches off all references to the cursor position, so that you will not see any figures at the bottom right, as shown above.
Absolute
This provides an “absolute” measurement, in X and Y from the toe on the 2d flattening.
Relative
This enables you to select a specific 0 point. I.e. where you click the cursor will become the 0 point and wherever the cursor is moved will be relative to that 0 point.
Distance
This works in a similar way as above, providing a measurement from the 0 point that you select to a specific point on the screen.
Cursor Constraint
The following commands control how the cursor moves on screen.
Vertical
When selecting this, the cursor movement is restricted to movements in a vertical direction only.
Horizontal
As above, but the cursor moves in a horizontal direction.
Free
This removes any restrictions and allows free movement of the cursor.
Cross Hairs
Selecting this function changes the cursor to a vertical and diagonal line on the screen, as shown below. This can be switched off by selecting the function again.
Figure 34: Cross Hairs cursor.
Cursor Shape
The two options within this function allow you to change the cursor to either an arrow or a cross. The two options are shown below.
The cursor mode can be changed allowing you to move the image around on the screen or make selections. A description of each is provided below.
Pan

This will “zoom” the image in or out on the screen. You can either draw a box around the area to zoom, or use the left mouse button to zoom in and the right mouse button to zoom out.

You can change the spacing of the grid to suit your needs. The default is set at 10 and the example below shows a spacing of 20

Offset
The Offset sets the grid to align to the centre of the shell or image on screen, and the default is 0. The example below shows it set at 5, and you will see the grid has shifted 5mm from the centre.
Figure 50: Grid shifted 5mm up from centre line.
Rotation
This function changes the way the grid lines flow. For example, at present the rotation is set at 0 and the lines run straight in all directions. In the example below the rotation has been changed to 5mm.
Figure 51: The rotation of lines changed to 5.
Click to
The “click to” functions dictate how lines are drawn within the grid None
When the “None” function is selected, lines can be drawn freely within the grid.
