18、to develop lisp application, note: r14 is the final version of the lisp file content open autocad, lisp in cad 2000 file content is encrypted (the author is studying decryption program)20. autocad secondary development tools are many, lisp would have had, rll provides ads (acad tools develop system)

19、, provides the ads in the r12 c compiler for real mode (such as bc, msc) support, provide arx r13 (acad tools runtime extend), provided the vb automation r14, the automation have made it possible to vb write cad program, the desire for cad programming has a best choice, no need to learn the ads, arx

20、, object arx,autolisp dnd join autocad programming world.21. user-defined lisp files must be automatically in autocad, so you need on acadrl4. add user lisp lsp file into the statement, acadrl4. lsp (early version for acad tools lsp), like the dos autoexec bat, be sure to make good use of, among the

42、buttons provided by the system right-click any tool button pop-up "toolbars" dialog box, then right click on the button pop-up "stretch" tools "button proporties" dialog box, in the "macro" box c c_stretch after typing spaces and the c after you click on the h

43、andle button, you can select the target action.38. autocad r14 users usually adopt system is given a default format save, save this format of disadvantage is that the file space is large, can，t use low version of the application (such as autocad r12, autocad r13) to open, to avoid the waste of disk

44、space, you can "save drawing as dialog "save the type" select "autocad r12 / lt2 drawing，z format inventory. for example, the same dwg file is stored in two different ways, which are 87kb and 58kb respectively. the difference is considerable and the latter file can be opened in t

45、he r12, r13 version of the application. this approach is especially useful for low profile userssometimes when you open the dwg file, the ，zautocad message" dialog box prompts ''drawing file is not valid" and tells the user that the file cannot be opened this case you can exit the

46、open operation first, and then open the f订e menu, choose z，drawing utilities/recover，/ command, or on the command line directly with the keyboard input "recover", then "select file" to restore the file dialog input, confirmed system began to perform a restore file operationsthe c

47、hinese-style menu. copy the acad mnu file from the support directory as chinese mnu. open chinese mnu with a slate a closer look will find that there are many * * * pop entries, each defining a drop-down menu. change the english command name in quotation marks to chinese and save the memory. enter the menu command in r14, load the chinese mnu menu file, and the drop-down menu becomes chinese you can also load the a
