Polyline transparent 'so

[ozimad]

Hi!

I am using autocad civil 3d 2008.

I am writing a lisp and want to use pline command in it, and use 'so - tranparent commands. But cannot select them. Writing by hand i can select them.

Any ideas whay?

 

the error

_.pline

Specify start point: '_so

Invalid point.

; error: Function cancelled

Is there no way you can call 'so' directly?

Thanks it works!

Can somebody explain how i can run _.so get the aligment i need and put all the data in.

(command "_.so" "something here to ask for aligment" and "data")

 

How does data must look like

 

I have this code now

 

(defun c:papl ()

(vl-load-com)

(setq al (ssget)) ;;select aligment,but i dont realy want this here because it ;;;is possible to select another object not aligment,

(command "_.so" al "10" "5" "20" "10") ;;;inputing data this way i get an erro

(princ)

)

 

 

 

Command: papl

Select objects: 1 found

Select objects: _.so

Select alignment:

Specify station: 10

Specify station offset: 5

Command: 20 Unknown command "20". Press F1 for help.

Command: 10 Unknown command "10". Press F1 for help.

Hey, I decided to change the concept of my lisp. Now I know how i can get without intersection points. I will use aligment and tranparent commands.

I want to bulid a road with the additional slowing line. I allways have an aligment so i want to use it, the concept is i do not need to do the geometry intersection points finding, just simple maths. I use pline=>'so command to find the point coordinate, My code now looks like that.

 

(defun c:papl ()

(vl-load-com)

(setq al (ssget))

(command "_.so" al "10" "0")

(princ)

)

 

in console it gives me

 

 

Command: PAPL

Select objects: 1 found

Select objects: _.so

Select alignment:

Specify station: 10

Specify station offset: 0

Command:

Command: (21.9795 19.8182 0.0) ;;;i need to get that point and use it in building polyline

 

Can somebody help me with getting the point, thanks!
