2. Although you installed the CAD font patch, still cannot display the text well, please check whether you have the relevant font file in ZWCAD installation directory. Because we know the patch have not included all kinds of font, if drawing was created with a rare or special font in other application, in this case maybe the text cannot be displayed correct. So you should have the relevant font file and put them in ZWCAD installation directory.
3. If the problem happens in previous ZWCAD version, please try it in the latest version to see if the problem is still exist. Because the latest version has more improvement in the performance.
