I have always entered a chord height of zero, which Pro|E will notallow, but it will then put in the minimum value allowed. This isdifferent for every model, but produces the best STL possible. There are two caveats, however. Sometimes, the minimum value will fail.I then increment the value slightly and try again. Sometimes, theminimum that will process produces ridiculously large STL files. Again,I bump the value until I get a good compromise between file size and STLquality, based on the on screen appearance. By using the 'Apply' buttonyou can create the file and leave the dialog open in case you have tochange the values and try again. 'Apply' and 'OK' both create the fileon disk, so once you've go the settings you like using the 'Apply'button, you can use the 'Cancel' button so you don't have to wait for itto process.Doug Schaefer
