ä½å¥½summer xia, at first you must create a file which called for example test.pts Now you must add in every line the number zero! Because the first value is for x the second value is y and the last value is for z. 0.997504 0.000340 0 0.977573 0.002951 0 If you have done this, create a new part. Then Insert->Model datum->point->offset csys datum point. Choose now the coordinate and click to the button "Import". Select the file test.pts Good Luck! Jürgen 约æ¹
