WuXuan 2012/09/12 11:26
      yeah,because the that are electronic components,so the dimensions are small

try Draw and the DATA EXCHANGE COMMANDS ("Test Harness User's Guide", thug.pdf)

pload ALL
ReadStep <document> <file_name>
Xdump <document> [int deep {0|1}]
XShow <document> [ <label1> ]

i am sorry , i cant understand.
can you give me an example? i think it is more useful to me

Draw commands:
pload ALL
# pload ALL load all plugins
ReadStep D thefile.stp
# ReadStep read the STEP-File in the document D
XGetOneShape aShape D
# XGetOneShape make one Shape of the whole document
#init the viewer
vdisplay aShape
# display the shape
Select the view window and press 5 (to select shells, enter "vhelp" to see help and filter options).
If you move the cursor over a shell (normaly an assembly) it will be highlighted.

If you want to display only one assembly you can use the following Draw commands:
Xdump D
# Xdump display the assembly structure on the Command line window
# use one of the labels for XGetShape
XGetShape aShape2 D 0:1:1:3
vdisplay aShape2

for more commands look at "8.7 XDE general commands" of the thug.pdf

Or try if you only want to view the STEP-File.
