Zhongwang CAD Tutorial: Using the Parameter ZW_XTINSERTDWGREF

Thread Content

There are many commonly used parameters in CAD systems, and engineers can set certain default properties of the CAD software according to their own usage habits. Taking Zhongwang CAD as an example, I recently discovered a very useful parameter while using it: ZW_XTINSERTDWGREF, which I would like to share with everyone. How exactly is this parameter used? I know an engineer in the communications industry whose drawing* habit is to create a standard drawing frame for a facility and save it as a DWG file; this standard file contains all the block definitions needed for that field of work. Whenever new drawings are created in the future, this file will be inserted as a block reference, allowing all the block definitions to be called upon flexibly. Then, while using Zhongwang, it was found that the inserted block references could not call the blocks defined within them. It was later found that this was the reason the parameter was turned off. For example: I created a standard drawing frame in which 5 block definitions were defined: http://www.zwcad.com/shequ/uploadfile/20110824-cad1.jpg. Then I deleted those blocks, keeping only the one with a circular shape, and saved the file. So, when drawing again, first insert the previously saved “standard” as a block reference by using the Insert command; at this point only block 1 (the circle), which is the referenced block, can be reused, while the other 4 blocks seem to have been defined for no reason. http://www.zwcad.com/shequ/uploadfile/20110824-cad2.jpg This is because this parameter is disabled by default in ZWCAD; so let’s turn it on to see what happens. First, restart Zhongwang CAD and modify the parameters (note: you must enter the setvar command before accessing these parameters). ) Enter ‘setvar’ in the command line, press Enter, then enter _zw_xtinsertdwgref and set it to ON. After that, go to http://www.zwcad.com/shequ/uploadfile/20110824-cad3.jpg and insert the block reference as a ‘standard’ block by using the Insert command; you will see that the blocks defined earlier can be reused 100% of the time. http://www.zwcad.com/shequ/uploadfile/20110824-cad4.jpg This simple example shows that this parameter controls whether a block definition without a reference can be inserted when a block is inserted. Please keep two points in mind when using it: (1) ZWCAD has this parameter set to off by default ； (2) SETVAR must be entered first before accessing this parameter.
