What is Spacelin
Spacelines/Flatlines are an Autocad extension to create auxiliary
construction lines on a special layer.
- You can place lines at absolute positions in space or in positions
relative to other entities in your drawing.
- Every entity that has straight edges, including the vertical edges of
extruded entities (by thickness), entities within blocks and edges
within acis solid models, can be selected as reference.
- The simplest ways to place lines are in absolute positions parallel
to an axis of the current UCS, or at a specified angle (right hand
or left hand) parallel to one of the main planes of the current UCS.
- Angle references can be selected from existing edges, and relative to
any main axis of the UCS.
- Other methods to place lines include positions relative to other edges
in the drawing, like parallel, normal (perpendicular), interpolated,
and shortest distance (perpendicular to two edges).
- Extent of lines is limited by a 3D frame, which extends the concept
of drawing limits to three dimensional space. There is a seperate set
of frame extent values maintained for each modelspace and paperspace.
- Most functions exist in each a 2D and a 3D version. In 2D, points and
selected edges will be projected to the current elevation before
processing. In 3D, you have complete spatial control.
More details:
You can create lines in the following ways:
- Parallel to X/Y/Z Axis of UCS.
- Parallel to X/Y axis on current elevation.
- With angle parallel to XY/YZ/ZX plane of UCS.
- With angle parallel to XZ/ZY plane of UCS.
- With angle to XY/YX plane on current elevation.
- Parallel to a vector in space/on current elevation.
- Along two points in space/on current elevation.
- Parallel to an edge in space/on current elevation.
- Normal (perpendicular) to an edge in space/on current elevation.
- Interpolating edges in space/on current elevation.
- Normal (perpendicular) to two edges in space (shortest distance).
Multiple lines are created as:
- Grid on current elevation (ignore frame).
- Rectangle on current elevation (ignore frame).
General utility commands offer to:
- Set/show 3D limits.
- Switch layer ZZ_SPACELIN on/off.
- delete visible construction lines.
- List available commands in 2D/3D.
Currently supported platforms

If you miss your favorite platform here, please contact me. We might
figure out a way to support your platform too, provided you are able to
compile ads/arx applications for it.
Warning
This program will not replace the power of your spatial
imagination, it can only try to enhance it.
It is designed as an auxiliary tool to help the (more ore less
experienced) user to locate points in space that would be even
more difficult to find without.
Some of the functions require a significant amount of geometrical
and mathematical understanding to be successfully applied in all
variations.
But of course, this should not keep you from trying!
"Support"
I expect the program and the manual to be self explanatory for
users who have some experience with Autocad and 3D modelling in
general.
If you still have questions cannot be answered neither
with the manuals of Autocad, nor with the included
documentation (particularly sections
"Diagnostics", "Caveats" and "Bugs and Limitations") nor by the local
guru, you might try to reach me by mail through the link below.
