Comsol with Matlab

Hi evrybody!
I have such a problem: suppose it's common problem, when I export project as fem structure from Comsol to Matlab and trying to write some script in which I vary programmatically draw properties, I can't do this. the result the same. and even I've changed draw property - nothing changes in a solution!
for exemple I set new properties in 5th objects fem.draw.s.objs{1,5}=ellip2(0.1,0.3,'base','center','pos',[0,0]);
I tried another way: when I save project from Comsol as m.file -
% Geometry
...................................
g9=flbinary('g9','draw',flbinaryfile);
draw.s.objs = {g1,g17,g2,g8,g9};
draw.s.name = {'CO2','E1','R1','R2','R3'};
draw.s.tags = {'g1','g17','g2','g8','g9'};
.................................
I think nothing has been changed because draw properties have saved in some file, maybe
here we see g9=flbinary('g9','draw',flbinaryfile); what's the "flbinaryfile"? where it has been written?
and the main question does exist easier way to change draw properties then re-write whole script?

Hi
in v3.5 when you "reset" your file and you had a rather "complex" geometrical model, COMSOL by default saved it into a binary mphbin file (it's written higher up in the .m file somewhere). This is indeed rather annoying, as I cannot remember how (or even if possible) to modify the content of the binary file afterwards.
But you can easily reload the file and the geometry that way

Good luck
