部份其實曾出現在免費的插件堆中....
但這個非常全面的.....
也能看到新V8 sdk的開放度....
操作好自主及直觀化....減少了介面數值的操作....
好有型格....
希望下版LW可以吸納這個.....

This documentation is the very concise description of the LWCAD package. The routine LightWave knowledge is necessary.
A few notes about the LWCAD before you start:
Every tool in this package works with the snap to point ability. Every tool handle works in ORTHO mode with pressed <ctrl> key. All geometry created and modified is based on the LightWave curves. Every tool works only in primary layer. Some tools contain a special tool buttons usable directly in viewport. Line segments and joined curves uses double points in curves.
Some LightWave tools are not familiar with double points therefore please use only curve to poly tool for convert curves to polygons!
LightWave curves are not very precise. For low curvature curve segments the error is negligible, in high curvature curves the error is significant. Use refine curve tool to lower high curvature objects!
Check your content directory in General Options panel. The content path must be real. Otherwise the Shape Library will be functionless. Use automatic installer for installing LWCAD.
Read the Install Notes file first.
Snap Modify Usage:
This subset of snap modify tools works with all types of geometry elements used in modeler. Not only curves.
Move snap tool :
The tool has two modes:

The tool works in 2D and 3D viewports.
Note:
The snap to point ability in 3D is bordered with the circle region. If you move handle outside of this region there is necessary one more mouse click to recount snap region around last mouse click. This disadvantage is caused by limited possibility of the lwsdk . But it works. Just one more click is necessary.

Merge Curve command:
Merge Curve removes redundant curves.
Connect Curves command:
Connect Curves command makes connection between ends of two open curves. Intersections are not taken in account. Very usable command after offset tool operation.
Curve Knife tool:
Curve Knife tool provides a curve intersection operations. It has the two visible handles and next one invisible center handle.
The tool has three modes:
