The "Lines" tool can be used to create 3D lines in the scene. Lines can be used for annotating 3D polygonal objects, as well as fast representations of true 3D objects.
By default, a vertical line of length 2 is created, with one spline control point at each end. The line manipulator works the same way as all other spline editors in Ez3d. See "Potter - Spline Editing" for a detailed description of spline editing. You can move one or more points, create new points within and outside the existing spline, delete one or more points, and so on. If you have the "Transform" interface up (See "Attribute - Transform"), you can get the precise location of the cursor. You can also select more than one point using the left mouse, and type in precise location values in the "Transform" text boxes.
Object Name
You can give a meaningful name to the main object using the "Object Name" text field, and pressing "Ok".
Spline Steps
This can be used to control the fineness of the curve. Set steps to 1, if you want straight line segments.
Width
This specifies the pixel width of the line. By default, lines are 1
pixel wide.
Pattern
Using this option menu, you can set the pattern of the line.
Join Ends
This option can be used to keep the ends of the line together all the
time, forming a closed loop.
Markers
Use this to display or turn off markers for the spline control points
Finer
If you have a region of the spline selected using the left mouse, and choose "Finer", you can double the number of spline points in the region. This allows you to add more detail to that area.
Delete
You can delete one or more spline control points by selecting them using the left mouse, and choosing "Delete".
New
This allows you to start on a new curve without having to close and
start it again.
Close
This closes the "Lines" tool. Since you cannot select any other object or perform other scene operations while the "Lines" tool is up, you should close the tool as soon as you are done editing.
