Hello,

I started during what I supposed would be a very simple task, I still believe it is, but I ran into some problems. I want to create a small check mesh script where some of the output are pictures of different parts of the surface mesh.

In my first attempt I used the tdv library commands to set an appropriate view and then take a picture of that. This method worked without flaw. But since my geometry is very large and varies somewhat in shape from case to case, it is not allways straight forward figuring out where the surface that I want to take a picture of is located.

So I came up with another method of doing it. I simply blank out all the parts except those which contains the surface of interest, then i zoom to fit, orient the view and take a picture. Should be straight forward.

The problem is, when I execute the replay script, the blanking out part is not reflected in the viewer.

I can enter the commands manually one by one and it will work.

So, I'm sure that all my commands work, I'm just missing the bit where I force the viewer to update. Can anyone here help me out with this problem?



Example of the commands I use:

# Hide every type except surfaces
set family_list [ic_geo_list_families] 
ic_geo_update_visibility point $family_list 0
ic_geo_update_visibility curve $family_list 0
ic_geo_update_visibility surface $family_list 1
ic_geo_update_visibility density $family_list 0
ic_geo_update_visibility body $family_list 0
 
# Show all surfaces as solid with wire frams
ic_geo_configure_objects surface 1 solid 0 0 0 0 0 0 0 {} 0 0 0 0 {} 0 0 0 0 0 0 0 0
 
# Alternatively use
#ic_uns_subset_configure All -shade flat_wire
#ic_uns_subset_configure Selected -shade flat_wire
 
# Hide all parts
ic_uns_update_family_type visible {} {!NODE LINE_2 QUAD4 !HEXA_8} update 0
 
# Show the parts I want to take a picture off
ic_uns_update_family_type visible {_SRF_1 _SRF_2 _SRF_3} {!NODE LINE_2 QUAD4 !HEXA_8} update 0

After spell checking my original post I found the error in the code, it was simply a case of copy-pasting lines and forgetting to update properly.

If anyone can use it here is my code to take pictures of the surface mesh. It is missing a check to see whether the mesh is loaded but is otherwise functional.

The code is intended for a replay script and can not be run in batch mode.

Dear friend,

I want to take a picture of my Geometry and Mesh in Batch model. But I can't change current view using ICEM script command.

I found your method: "In my first attempt I used the tdv library commands to set an appropriate view and then take a picture of that. This method worked without flaw. "

But I don't know TDV Library Commands, Can you help me?

Thanks,
Baozhi

Take a look in your ICEM install directory under lib/tdv/
there should be a couple of tcl files in there, which can give you some inspiration.

some example of usage:

# Find default viewer
global tdv_default

# alternatively
global tdv_current_viewer

# Set isometric view
tdv_isoview $tdv_current_viewer

# Zoom to fit
tdv_scale_to_fit $tdv_current_viewer

# Rotate view dynamically 360 degrees
for {set view_angle 0} {$view_angle < [expr 2 * 3.14159]} {set view_angle [expr $view_angle + 3.14159 / 180]} {
tdv_rotate_axis $tdv_current_viewer 0 1 0  [expr 3.14159 / 180]
tdv_trans_update $tdv_current_viewer
update}

Thank you very much for helping me.

Now I can use the codes you give me to adjust the current viewer in GUI. However, I cannot take a picture. The command IC_Print doesn't work in batch and GUI model. Is there other commands or methods?

I hope you can give me some good advice.

Thanks.

there is a mistake, tdv_current_viewer no such variable, when I do the following code in batch model:

# Find default viewer
global tdv_default
# alternatively
global tdv_current_viewer
# Set isometric view
tdv_isoview $tdv_current_viewer
# Zoom to fit
tdv_scale_to_fit $tdv_current_viewer

Then use tdv_default instead.

Unfortunately you cannot take pictures of your geometry/mesh in batch mode, since the graphics are not rendered. You can, if it's no difference to you give the replay script as input when starting ICEM (-script REPLAYSCRIPTPATH), if you include an exit command at the end of your script, it will open the GUI execute your script and close down again.

I try to replace tdv_current_viewer with tdv_default.

# Find default viewer
global tdv_default
# alternatively
global tdv_current_viewer
# Set isometric view
tdv_isoview $tdv_default
# Zoom to fit
tdv_scale_to_fit $tdv_default

The problem still a problem.
'can't read tdv_default, no such variable.

[Sune]

Are you running the commands in batch mode? tdv_default is the default viewer window, which doesn't exist in batch mode.

[baozhi xie]

Yes, I run the batch model. I want to change the view and take a picture by batch model. However, the two things all failed. Could you please give me some advice?
Thanks,

Baozhi

I already wrote in my previous post #7, that doing what you want in batch mode is not possible (to my best knowledge) and my suggestion to an alternative approach.

Thank you for your kindness. I didn't describe my question clearly. Please help me. I didn't add -batch in my command.
