    There’s AutoCAD plug-in “MeteorSpec” that calculates the specifications of cables.
    Program has a Data Library where all the data about the cables you use are saved.
    Program can generate reports as specifications (summarized lengths per cable type) or as explications (list of all cable with detailed information).

    The program can be configured to use in any field of design where calculation of total lengths and total areas is needed.

    Look at Autodesk Exchange apps.

      You can use SIMARIS Design (Siemens) or Rapsody (Schneider Electric). Both are free to download from manufacturer’s sites. Try googling and you’ll find them for sure.

    Hello everyone.

    I’m pretty new over here and I need some help.
    On the project that I’m working I need to design some time current curves for specific relays. The time current curves must have more than two characteristics(Overload and short circuit) and I couldn’t find any software for designing such specific curves(I’ll give an eg to be more specific: I need a curve where the first drop is at 1500 A in 5 sec, the second is at 3300 A in 2 sec a third one at 10 000 A in 0.1 sec). The only one that I found useful is CYMTCC software. In the older version of CYMTCC(4.5) I can’t design only with two characteristics. In the new version, which is 5.0 I can add a new characteristic but on the trial version I can not export, save or print the project. And I can not pay some hundred dollars only for some of this curves.
    So please, if you can, tell me some software where I can design this curves.
    Thanks a lot,
