1, missing font;

2. The opened file is too large;

3. The computer configuration is too low.

Second, the solution to CAD drawings stuck:

1, every time you edit "block", it will become a good card when you exit. At this time, you can use the shortcut key "z", then space, then "a" and then space, so that all the graphics aRE displayed, and then use "re" to regenerate the model, which is good.

2. The more pictures you draw, the bigger the picture file will become, and the more memory you have, the more stuck it will become. You can use the shortcut key PU to clean up and delete useless layers, blocks, labels, words, etc. In this file. After cleaning up these extra things and lines, the document size will be reduced. You can always try this method, which is very effective!

You may think that your mouse will slow down the operation speed of your hand, and you will feel dull and slow. One reason is that you pressed "Grid" or "Capture". Press F7 or F9 on the keyboard to turn it off, and it's OK. Of course, there is another way to save the current drawing as a DXF file. This method will make the imprint of "education edition" disappear, and it will also remove many useless parameters loaded. Useless parameters will cause CAD software to get stuck. Why? Because there are many internal parameters in CAD, CAD will get stuck.
