Tool function: sometimes we receive a large number of cad drawings, and only click one part of them, and the whole drawing is selected. For example, directly using the explode command or unmarshalling command under cad has no effect, because the drawing uses "multiple insert reference". Instructions: Execute the ap function, load these two files, execute the exm function, select multiple blocks, if there are many levels of "Multiple Insert Reference", you can use it several times, and finally use the explode command to decompose the whole drawing.

With the development of automobile lightweight, more and more metal parts used in automobiles are replaced by high-performance engineering plastics, especially engineering plastics PA, PC and PBT, which are the most abundant plastics used in automobiles at present. Polyamide PA is mainly used in power, chassis parts and structural parts, while polycarbonate PC, thermoplastic polyester PBT and other materials are mainly used in electronic and electrical parts and structural parts;Land Rover and Chery are better models with lightweight design, and many of their parts are made of engineering plastics."The specific gravity of general plastics is 0.9~1.6, and even glass fiber reinforced composites will not exceed 2.0, while A3 steel is 7.6, brass is 8.4, and aluminum, which has been considered as the lightest, is 2.7. This is one of the important factors that plastics can become the preferred material for automobile lightweight. So, with the development of new plastic materials in the future
