> Thanks for the example. Running the script does gives some errors about missing filenames in rt.exe but I get the idea anyway. But I do not understand how to assign groups within a lua-script. But in the FEMM editor I can add a group number so I guess there must be a way to do it within then script.

Then, you can select everything at once and rotate it via. For example, if you wanted to select everything assigned to group number 2 and rotate it through some angle programmatically, you'd do: seteditmode("group") selectgroup(2) move_rotate(0,0,angle) There's an example that I put up on the website at http://femm.berlios.de/movie.zip This is an example of a switched reluctance motor that repeatedly the rotor and saves a bitmap of the solution. There are also some included programs that convert the saved bitmaps into gif files (imagemagick's "convert" program) and glue them together into an animated gif (via "gifmake"). If I have been careful enough to include all of the right dll's in the distribution, the end product of the script should be a gif movie of the SRM spinning through 30 degrees. Dave.

My program is now creating a lua-script that, after saving a bitmap, rotates magnets a few degrees (thanks Dave) and makes a new bitmap, until 360 degrees. Not everything have to rotate so I have to select the nodes first and rotate them (arc and segments are following). Then I have to select the blocks and rotate. Since I loose the nodes selection because of chancing edit mode the script has to rebuild from scratch the next time and make a bigger step to rotate. This is normally no problem since it takes now 1 minute to generate 36 bitmaps but when running as a web service I need more speed since I have to convert to an animated gif as well. The question is: Is there a way that I can select nodes and blocks at the same time? Because then Ican rotate the selection step by step and generated bitmaps in between. Thanks, Eric.`
