Create Surface by lisp in Auto cad civil 3d

[reza]

Hi

When I want to create a surface from file like this:

 

(if (findfile "D:/DATA_TEXT/1.txt")

(createtinfromfile "D:\\DATA_TEXT\\1.txt" "Surf1" "s1" "Standard" "ENZ (comma delimited)"))

 

I must first create a surface manually in civil 3d

otherwise can not create surface by lisp

please help me

If you dig deep in the Autocad directory you should find the directory that has sample code for creating a surface from points file. I will see if I can find it.

Dear BIGAL

My issue is not creating a surface form point file in Auto cad Civil 3D. The real problem is I can't create my surface based on data point file automatically (by which I mean through lisp) before I create at least one surface manually. Attached you may find data point and code files.

Hi

How to confirm this Dialogue Box in lisp :

 

(command "_AeccCreateSurface")

[BIGAL]

I thought I posted already to search under autodesk......\sample\com for surface example code. Pick the VBA option you can dump it and write in VL Lisp if required.

Moderator need to merge other post by reza its the same subject.

 

Again as I posted in your other post you can do it all automatically search for the example code thats exactly what it does create a surface and add pts making a TIN.

Dear BIGAL

I did not get what you said please give further explanation

[BIGAL]

There is sample code for creating surfaces from a points file you just need to change a few values in the sample like your data file name surface name and style to be displayed.
