i have structured my text file (file.txt) according to ANSYS command file, now i want that when i put this file again in autocadd than it results in a drawing of the same structure frm which the text file is generated.

i am posting myt text file also...

/title , frame

/PREP7

!Enter the height and width of the frame:

300, 400

! Define Keypoints

K,1,x1, y1 ! keypoint, #, x, y
K,2,x2, y2
K,3,x3, y3
K,4,x4, y4
K,5,x5, y5
K,6,x6, y6

! Define Lines Linking Keypoints

L,1,2 ! L,keypoint1,keypoint2
L,2,3
L,3,4
L,4,1
L,4,6
L,4,5
L,3,5
L,3,6

! element definition

!

ET,1,LINK1 ! element type #1; spring element
R,1,3250 ! real constant #1; Xsect area: 3200 mm^2
MP,EX,1,200e3 ! material property #1; Young's modulus: 200 GPa

LESIZE,ALL, , ,1,1,1 ! specify divisions on unmeshed lines
LMESH,all ! mesh all lines

!
FINISH ! finish pre-processor
!
/SOLU ! enter solution phase
!
! apply some constraints

DK,1,UX,0,,,UY,UZ ! define a DOF constraint at a keypoint
DK,7,UY,0,,,UZ

!
!

FK,1,FY,-280e3 ! define a force load to a keypoint
FK,3,FY,-210e3
FK,5,FY,-280e3
FK,7,FY,-360e3

!
SOLVE ! solve the resulting system of equations

FINISH ! finish solution

/POST1

PRRSOL,F ! List Reaction Forces
PLDISP,2 ! Plot Deformed shape
PLNSOL,U,SUM,0,1 ! Contour Plot of deflection

ETABLE,SAXL,LS, 1 ! Axial Stress
PRETAB,SAXL ! List Element Table
PLETAB,SAXL,NOAV ! Plot Axial Stress

to make more clear, i have generated my text file by using VBA programming in autocad, i know that to get drawing from this text file also need programming in VBA but i am not getting any idea how to do it.

the problem, to export text file to ansys is solved so the problem remains is the above one.

thanks

as i posted text file in first post....i want to make the following part of the file more clear...

! Define Keypoints
K,1,x1, y1 ! keypoint, #, x, y
K,2,x2, y2
K,3,x3, y3
K,4,x4, y4
K,5,x5, y5
K,6,x6, y6

in above part actually X1, Y1 have some values...so actually above part is like this in text file..except this everything is correct in file and written as i want to.

! Define Keypoints
K, 1,4578.2531,7919.0487

K, 2,11346.8678,11826.9102

K, 3,11346.8678,3072.2707

K, 4,4578.2531,3072.2707

K, 5,11346.8678,7919.0487

K, 6,4578.2531,11826.9102
