Let Your Drawing Respond Faster in ZWCAD
Processing speed of CAD software is one of the most concerned issues of every user. Fast speed can be achieved directly by either software or hardware upgrade. In case of ordinary PC configuration, how can we further raise the speed even without software update? Here are some tips: 1. If you frequently specify the color or linetype for certain entities instead of using Bylayer or Byblock features, data will increase dramatically in the drawing, and it will take more time to process these data. It is suggested to create adequate and appropriate layers to which entities of different meanings or properties can be assigned respectively, so that the option of Bylayer and Byblock can help to reduce the amount of data stored. 2. If there are lots of layers in a drawing, some of which contain complicated entities seldom used, then you can freeze these layers, so that they would not regenerate with other layers, and result in processing time saving. 3. Hatch (Fill) is a kind of entity occupying much RAM. Too much hatches would significantly drag down the processing speed. To maintain high speed: (1) Do the hatching at the last step, so that there are no hatches affecting the speed during previous drafting steps. (2) Assign all hatches to a single or some specific layers and freeze some or all of them if possible. Then they will not regenerate with other entities. (3) In the Config dialogue box, select the Display tab and check the option Not display hatch while zooming. Entities such as Solid, Donut and Trace have another kind of fill. They can be displayed faster by setting OFF for FILLMODE. 4. Text also has influence on the speed of ZOOM, REDRAW and REGEN. Simplifying the display mode of text could help to increase the speed to a large extent. (1) Use a simple text font during the preliminary drafting work, and then replace this font with desired ones at the final stage when there are no more modifications to other graphic entities. (2) Use QTEXT to enable quick display of text. After the command is activated, boundary frames of text areas are displayed instead of text themselves. 5. In the case that we have to insert raster images: (1) Go to the Config dialogue box, select the Display tab and check the option Pan and zoom with raster & OLE, if it is not necessary to view raster images while doing PAN and ZOOM. (2) Use the command IMAGEQUALITY to choose a low quality display mode, when we don’t need to view images with high quality. 6. When REGENMODE is set as ON, ZWCAD will regenerate graphics automatically after executing some commands. Turning the mode off can help to save the time spent on automatic regeneration of graphics. 7. Entities often turn into dash line type for the purpose of highlighting when they are selected for modification. Sometimes such highlights take lots of time to display. So you can think of closing HIGHLIGHT if necessary. Not all methods might suit each specific case, but they do help if applied properly. When you get familiar with these features, drafting work could never be a difficulty in terms of speed, and you may find it easy and convenient to use ZWCAD in any situations.

Start up guide to become an Information security consultant
For the sake of efficiency, cost effectiveness and to focus on the core business companies world over are switching to outsourcing of IT security. It makes eminent sense too as the information security consultants are the experts of their domain and hiring them is much more economical option than maintaining a whole army of in-house IT security experts. This cost and efficiency factors combined with the ever growing threat from hackers and exploding online shopping and e-commerce market has made sure that more and more companies are looking for information security consultants to take care of their IT security concerns. All these factors have made the career of information security consultants quite promising. But before you get ready to jump on the bandwagon, wait and contemplate as to why a company would go for outside IT security experts. This would help you understand the industry better. Basically there are following three reasons which make a company go for outsourcing. 7. The required services are not available in-house and getting expensive new employees is costly and time consuming option. 8. Company is facing a tight deadline to finish a highly technical project and it is not possible to hire, train new employees and expect the project to be finished in time. 9. Companies need an independent and objective perspective which is not mired in the corporate politics and infrastructure. When you are clear about these basics you can start the process of being a successful information security consultant which is as following. Go wholeheartedly — There are no half measures when it comes to making a career. And certainly not when you are entering a field as fluid as IT security. The job outlook and growth is better than average and there are training programs and schools which offer specific curriculum, certificates and degrees in computer security. Do proper Research — Since this field is relatively new, the programs are new and not yet established. So go for a recognized and reputable institute which offers all encompassing curriculum in information technology (IT), consisting of but not limited to penetration testing, systems analysis, computer information systems, programming and networking. Steer clear of frauds — As with any growing field, IT security education field is replete with fly-by-night operators which are there just to make money and offer illegitimate courses which are not recognized and can’t get you a job after graduation. Don’t be limited to just curriculum — As extensive the curriculum might be, there is always space for more. So don’t just be limited to the courseware and keep on adding to your knowledge of vulnerability analysis, firewall management, virus protection, network and software safety, IT forensics etc. Add to you certifications — After or during your graduation you can opt for industry recognized certification such as “Cisco” Network Security certification, those offered by Microsoft etc. They will add value to your knowledge and empower your resume. Gain experience — Once you have graduated you should get industry exposure through school-sponsored IT internships and with entry-level IT jobs. They will help you understand the IT security threats in real time practical environment.Nirmalya Jain is an <a href= http://www.appinlabs.com/iso-27001.php> Information security management system </a> and specializes in <a href= http://www.appinlabs.com/ethical-hacking.php> penetration testing</a>, systems analysis etc. She is also an amateur writer and her write ups on IT security have been well received.
