Introduction to AutoCAD secondary development tools

Or ARX file formats into a VLX; provided AutoLISP source code debugger supports single-step debug interrupt and can easily access the variables and expressions, view data and AutoCAD AutoLISP graphic entity data; file editor in the editing AutoLISP and DCL documents to provide color support and maintain the legibility of documents; project document management system for maintaining multi-file application is very convenient; intelligent system provides an interactive console feature level (continued on page 28) the design and construction of the first metallurgical and mining 31, No. 3 hole 1.3.4 I applied the quality of construction in the deep hole drilling, if the fan of holes appear before the completion of the forward or backwards (Figure 4), it will change the minimum line size. 2 Select the desired blasting effect of technical measures for the mining sector in the deep hole blasting down the problems and the cause analysis, the following can be taken possession of the appropriate technical measures. 2. I enhanced the design and construction quality management hole in the hole under the acceptance criteria, ranked from the error surface with disabilities 0.1m, hole depth disabilities 0.5m, exclusive surface angle ± 2. Under this provision, surveyors marked the drilling rig site in addition to the center line, side opening hole row location and radiation centers, when the hole cut is complete, you must also enter the site inspection and acceptance. Found to have failed or the row of hole surface, must be completed or re-drilled holes. 2.2 to ensure the quality of charge and plug the charge density is the power of explosives and blasting the quality of the important factors. ANFO detonation velocity increased with the charge density increases, and vice versa smaller booster and even interrupted; required charge density greater than 0.85 ~ Zhang 9g/mL. To ensure the effectiveness of hole, should pay attention to the quality of the orifice of the plug to prevent the explosives fall or tumble in school. 2.3 milliseconds to establish custody and blasting equipment, periodic testing and inspection systems to ensure initiation detonators in the same paragraph, except in the initiation of the hole with the news section of detonating cord with a triangle connection, but for the loading of the millisecond detonators and detonating Cable and other explosive materials must be tested and checked in advance. At the same time I believe that the same paragraph, each hole having the same row of detonators are installed, each row in the same paragraph with only 2 to 3 Initiation to as detonators, the less the same paragraph, \Initiating the network to improve the reliability of network reliability, through professional and technical training should be required for initiation of personnel for on-line network, to transfer the various branches of the network length of the pipeline explosion equal to detonating, delay the same. initiation before making the final checks on the network must ensure that cuts of 2.5 wells, construction quality, Lane cutting cutting cutting Lane wells and the construction quality of the same effects related to mine blasting, so cut well, the location and the section of roadway excavation must meet the specifications design requirements. If that flag because of geological or other problems caused by cutting work well, Lane is not in place, you must take the appropriate remedial measures .3 results and conclusions Xishimen iron above the last eight years in a number of technical measures taken possession of, not only to improve the operational safety of the miners conditions, and recovery of ore Pat 75 or more, large lower rate than in the past 3O, secondary blasting explosives consumption decreased by 45, due to caving of ore blocks uniform, but also a corresponding increase in the efficiency of the electric rake. In short, to improve a pillar sublevel caving mining sector in the deep hole blasting down the quality of decadent will take possession of a comprehensive technical measures, such as in deep engineering design and possession, charge and jam, detonating equipment inspection, initiation network Road optimization, and cutting well, Lane reservoir engineering quality, etc., are indispensable. only every aspect of work to do in order to ensure that blasting to achieve greater economic efficiency mines.

These two tools should be a relatively sound, the majority of CAD developers should have the Au-toLISP or ADS program as soon as possible and switch to VisualLISP ARX, and to fully and rationally utilizing a combination of these two tools to organize the development, realization of commercial CAD software will no longer be elusive thing.
