Pymel Volume Curve

#1

Hi

I try to create simply thing via pymel.

I create a curve, than I create 3D container from Fould tab.
First I select my curve, than 3D container to get 2 selections.
Next step is click on Field/Solvers tab and select Volume Curve

the mel looks like that:

volumeAxis -pos 0 0 0 -m 5 -att 0 -ia 0 -afc 1 -afx 1 -arx 0 -alx 0 -drs 0 -dx 1 -dy 0 -dz 0 -trb 0 -trs 0.2 -tfx 1 -tfy 1 -tfz 1 -tox 0 -toy 0 -toz 0 -dtr 0  -mxd -1  -vsh "curveShape1" -vof 0 0 0 -vsw 360 -tsr 0.5 ;
// Result: volumeAxisField1 // 
connectDynamic -f volumeAxisField1  fluid1;
// Result: fluidShape1 // 
connectAttr time1.outTime volumeAxisField1.time;
// Result: Connected time1.outTime to volumeAxisField1.time. //

I know how to convert that into pymel. But does not work.

also when I copy the mel and I paste that into mel tab to run this 3 lines of code. It works but does not create what was created by clicking the tabs and using the mouse.

I need help, how to recreate a volume through the curve?

thank you

Yes, indeed you are right. Maya forgets to print some actions, e.g set the volume shape of the force field or connect the curve correctly:

curve -d 3 -p -13.208059 0 5.115273 -p -6.959342 0 4.97804 -p -2.278478 0 7.34021 -p -0.323914 0 5.268556 -p -8.788131 0 -1.988922 -k 0 -k 0 -k 0 -k 1 -k 2 -k 2 -k 2 ;
volumeAxis -pos 0 0 0 -m 5 -att 0 -ia 0 -afc 1 -afx 1 -arx 0 -alx 0 -drs 0 -dx 1 -dy 0 -dz 0 -trb 0 -trs 0.2 -tfx 1 -tfy 1 -tfz 1 -tox 0 -toy 0 -toz 0 -dtr 0  -mxd -1  -vsh cube -vof 0 0 0 -vsw 360 -tsr 0.5 ;
connectAttr time1.outTime volumeAxisField1.time;
connectAttr curveShape1.worldSpace[0] volumeAxisField1.inputCurve;
setAttr "volumeAxisField1.volumeShape" 7;

To find out what’s wrong you can always check the original scripts, in this case something like “createCurveField”. Just search for it in mayas script directory with a text editor and you can see what’s happening.
