Because the CAD file is too large to open slowly

Just do the CAD drawings, save the file will be very large, for this kind of imagination how to deal with it?

Problem Description: I was just learning CAD drawing, yesterday, according to the teacher assigned to work painting an office construction drawing, take back to the school opened very slowly, sometimes open, sometimes not open, the teacher said the file is too big, so open slowly, how to do?

Processing method: This is because the resulting CAD drawing contains a large number of extraneous tiles and some rubbish, resulting in large files. You can in the AutoCAD command input pu, press the space bar or enter, will pop up a cleaning box, select "Clean up", the irrelevant tile and some garbage clean, and then save, file size will be much smaller than before. Later, the paint will not clean up the garbage on the line. The file is not open because the file is too large, the school computer Configuration is low, this time you can try to press the ESC key to skip some because the file is too large caused by error reading.
