Best Program To Draw Electrical Circuits' title='Best Program To Draw Electrical Circuits' />Plan vs Auto. CAD Electrical Comparison. A peculiar topic and discipline in the field of CAD, from designing electrical circuits to laying out electrical schematics for a building, electrical CADing is a complete industry all together. Electrical designing for all scales, forms, architectures and even more practical applications need a solid software package to integrate the non electronic drawings with the electric magic. As a computer science major, I am not jumping cliffs to learn or even read about electrical CADing, but then again thats me. And the e CADing enthusiast should read on for a comparison of e.

How are they defined and which one is suitable for me Auto. CAD Electrical, or ECADe is another one of Autodesks products aiming as electrical designs and developments for pre production analysis and review. To most of the people who have used it, its like Auto. CAD with a few simple but useful built in functions and LISP scripts that automate the tasks of setting, up and other mundane tasks. A few additions to the tools and the above mentioned LISP support is all there is to ACADe. And I agree. See, in comparison, e. Plan was built ground up from scratch with the ideology of an electrical CAD package as opposed to a CAD package extension. Hence, e. Plan is a much more directed and flexible solution with a learning easier for the unbiased. Ex Auto. CAD users will obviously have a tougher time with e. Plan. In terms of previous usage, if youre coming from a company where all your built up libraries are in DWG and LISP format, then you should probably stick with Auto. CAD. e. Plan is a good solution, but not when you have years worth of effort precompiled in Auto. CADs native formats. An Important Difference. One huge difference is the fact that Autodesk uses Microsofts Access as the default database in Auto. CAD and hence that extends to the numerous products in the portfolio. This is for all parts, assemblies and any other drawingdesign related data or metadata included. Because of this, assembly and part response in real time is slow and you cannot reference wire numbers backwards when you need to add PLC addresses. In response, e. Plans back end technology is a secret but whatever it is, it works. With Auto. CAD you have to do it Auto. CADs way, mold your own habits and designing methodologies according to what Auto. CAD has laid out. Plan takes all of that out of its package and gives you freedom to design from single breadboard designs to multiple sheet referencing and printing so its all there. Which one is more efficient In terms of this design efficacy, it may even be a better idea to head over to Auto. CAD LT, if you are an Auto. CAD user otherwise e. Plan is definitely a good choice. Dont get us wrong. Auto. CAD Electrical would help on a bigger scale. Spreading out the wiring for a 1. Auto. CAD would help with because the civil drawings would for the most part, have been developed in Auto. CAD duh would be pretty complicated, not to mention the size. But if you take this one factor out, e. Plans problems and shortcomings start to fade away. People who have experience with the AEREBUILD command after completion of the design phase will know what were talking about here because any components hidden pointers will surely need a thorough second look. Learning Curve Another thing to remember is that due to e. Plans design, it is not just a click and draw software package with relevant context menus like Auto. CAD Electrical. This package requires you to be well trained in the know how of electrical components and the more you know, the more youll understand how it is different in terms of intelligence. Moving on, e. Plan is an open source software with a very friendly interface and to the point aids and support. And it needs to be that way because of the fact that it can be an alternative to ACADe even in terms of scales going one step ahead with its referencing system. Unlike ACADes dependence on Microsoft technology, everything can be automated and referenced for previous and new version comparisons. Seriously just try renumbering pages and see what you end up in both packages, e. Plan will surely have the references contact. Conclusion. All in all, one must remember that the ACADe package was first built for mechanical and civil drafting and designing, not for Electrical drawings. Plan is far more expensive, almost double the cost for the same license options as with Auto. CAD but the package lives up to its reputation and requisites. Any kind of task can be automated, if not automated as a software default whereas Auto. CAD completely misses out on some tools and functionality because of its primitive heritage.
