Atos 是控制点的质量（去除无效点）， 数值从 0 到 255 (由低到高)，那么低于此值的点将被忽略。 Ascii : Atos : Stl : Iges : Sampling: allows to import a certain percentage of the Digitized data, be careful, this will be done sequentially every x points will be kept. Scale Factor: the scan is very often performed on a scaled model, you may want to work on real size model, apply the given scale factor File Unit: your CATIA session is set up for a given unit. The file you import comes from the outside world and may be digitized in another unit. Set up the proper unit before importing the file Options : Replace : will replace the current cloud of points by this new one. Update: Will display the cloud of points along with its bounding box.
