Purpose
Project a stored 3D curve into two 2D CLINE curves.
Syntax
|
PROJECT ( KNUCKLE $W ) ( BUTTOCK ) ( SECTION ) ... |
Description
The selected 3D curve will be projected into the two user selected views. Two different views must be chosen. This will cause two CLINE curves to be created with their names derived from the name of the 3D curve and the view. These new curves will be stored in the CLINE directory and will be Data points will NOT be calculated for the CLINES.
The system will automatically display the projected CLINES for fairing in turn, which can be modified using the ADJUST command and the ACCEPTing. When the required changes have been made to both CLINES the 3D curve can be reconstructed using the CREATE curve-type curve-name MERGE command. See the CREATE command for further details.
Naming Convention
The names of the CLINES will be derived as follows:
|
3D-curveB |
for Buttock view. |
|
3D-curveS |
for Section view. |
|
3D-curveW |
for Waterline view. |
For example the command
|
|
PROJECT KNUCKLE aft SECTION BUTTOCK |
|
would create CLINES named afts and aftb. |
|
Note that because of this naming convention the number of characters in the name of a 3D curve that is to be projected is limited to a maximum of 7.
This example will project PLINE bar into BUTTOCK and WATERLINE views using CLINE 1 and 2. The AUTO option indicates automatic 3D fairing. If no second curve is given, then the merged curve will be of the same type as the projected curve. If the NOSAVE option is given then the CLINES will be deleted after the merge.
