I am about to insert a graphical image from an autocad drawing to my VB form. I don't want to calculate all the coordinates of the 3D sphere and cube that I need in my VB form so I impored the Autocad STL file containing the coordinates. Now problem is, I am able to copy entire file in my multiline textbox but not able to read the different coordinates from my textbox into arrays.

Help me !

Is there a delimeter in the text file?

Can you provide a copy of the STL file so that we can see the format.

VB has some nice tools for parsing a text file into an array but the one I am thinking of requires some kind of delimeter.

The first few line os the STL file looks like this when you open it up with wordpad:

solid AutoCAD
   facet normal 2.4543471e-001 -2.0337300e-002 -9.6919977e-001
      outer loop
         vertex 3.3246995e+000 5.9458172e+000 6.0272774e+000
         vertex 3.3291892e+000 6.0000000e+000 6.0272774e+000
         vertex 3.6493989e+000 6.0000000e+000 6.1083655e+000
      endloop
   endfacet
   facet normal 2.4543471e-001 -2.0337300e-002 -9.6919977e-001
      outer loop
         vertex 3.3246995e+000 5.9458172e+000 6.0272774e+000
         vertex 3.6493989e+000 6.0000000e+000 6.1083655e+000
         vertex 3.6405420e+000 5.8931124e+000 6.1083655e+000
      endloop
   endfacet

This is only a demo, there are thousands of line like this. I just want to get inside a line and then read a number which is in format 2.4543471e-001 separated from others by a space or a "."

I also want the first number to be put in X-array, second number in Y-array and third number in Z-array. Then go to next line of the multiline textbox and get other numbers likewise.

I have also sent you a mail with attached STL file, in case you want to see what the whole stuff looks like.
