Description
3D-Pipe is an AutoLisp program with a command named
3dP
, by CadToolChest, which functions within AutoCAD 2002, and later (possibly
earlier). It constructs 3D Pipe, with or without wall thickness, using
3dSolid objects. The pipe is constructed on the layer specified in the
laYer
option, using the current color and line type.
This program requires an additional CadToolChest file which must be downloaded
separately (see left margin).
Command Prompts:
The following are the prompts issued by the 3dP command:
CL WP at 1st end of Pipe/Extend/laYer/liNe/Quit/<12.0,0.0,12.0>:
CL WP at 2nd end of Pipe/laYer/Quit/<120.0,0.0,120.0>:
Diameter of Pipe/rePick/laYer/Rad/<12.7500>:
Pipe Wall Thickness/rePick/laYer/Solid/<1.2500>:
At the first two prompts, pick the center line end points of the pipe. At the 3rd prompt, enter the actual outside diameter of the pipe (not the nominal pipe size). At the last prompt, enter the wall thickness of the pipe, or "S" to make the pipe solid (use "S" to reduce file size and complexity). The default values are those of the previous pipe and remain during the current drawing session, or until changed.
Prompt Options:
Quit = Exit the program.
rePick = Reissue the first prompt.
Extend = Specify the distance to extend the pipe from the pick points. Values can be negative.
laYer = Choose from several methods to set the layer of the pipe. See Layer Options below.
liNe = Switch to selecting the pipe center line instead of picking two points. The option changes to Points which will return to the two point method.
Rad = Switch to entering the pipe radius instead of its diameter. The option changes to Dia which will return to enter diameter method.
Solid = Construct a pipe without wall thickness.
The Extend Options:
When the Extend option is used, the following prompts are issued:
Enter amount to extend 1st end/<0.0000>
Enter amount to extend 2nd end/<0.0000>
The value entered is used to shift the end of the pipe by that distance from the pick point for that end. A value of 0.0 ends the pipe at the picked point. A positive value extends the pipe by that distance. A negative value shortens the pipe by that distance. The values will be applied to all subsequent pipes until the value is changed or the drawing session ends.
The Layer Options:
When the laYer option is used, the following prompt is issued:
Layer for Pipe/O/C/<-Sol>:
O = The same layer as another object. Before creating the pipe, and additional prompt is issued to select an object on the desired layer. The pipe will be created on the layer of the selected object. This option makes it much easier to create 3d models with a complex layer system designed to isolate sections of the model.
C = Create the pipe on the current layer.
-Sol = The default. Create the pipe on the same layer as another object, but suffix the layer name with -Sol . Like the O option, this option makes it much easier to create 3d models with a complex layer system designed to isolate sections of the model, but works particularly well when selecting center lines for the pipe work points and the center lines have their own layer system.
