Request for XVII
Hi Was is possible for user to choose default file location for library collection elsewhere other than drive C, ie I keep all data in drive D which is sync or shared by external server.? The XVII can stay in program file ie drive C for example. Also include a link at the top RHS of the XVII window that jump to this forum. The google search does not provide top level?results?LTSpice from Yahoo.? Really useful to apply option to enable window control style on schematic, ie CNTR-D duplicate, CNTR-C copy, CNTR-V paste, CNTR-X cut, CNTR-S save, select and delete and so on or have custom key list with user choice (Save/load).? Thanks |

I want one! I think it is more likely they skipped some that Mike needs for the new multiple monitor display, or something like that. That's why it won't load in XP but runs fine in Wine. Also pure speculation. However, since IV will continue to be supported, it no longer matters. I can continue to use IV, and keep XVII as a backup for troubleshooting in case I run into a snag. I think others can do the same. Mike |

They reserved the name and transferred some files but they never actually moved. They disabled posting to the new group some time ago.

Dennis Tillman W7PF ------------------------------------------------------------------------------------------- It might be wise to do the same as Tekscopes. Start LTspice on groups.io so you are ready to make the move, but wait until it is clear what Verison intends to do. Even if it is feasible to stay, it would be a good idea to have a backup. You never know what is going to happen. Mike |

Henry's current transformer problem
Hello Henry,
From looking at the data sheet here are my guess for your CT core's physical parameters: Ae (core area) = 95mm**2 le (path length) = 66mm For LTspice the magnetic parameters are: Lm = 66m Lg = 5u (just a guess -- could be 1u to 20u -- adjust to match the inductance) For the magnetic parameters use (steel OR nickel-iron / permalloy): Bs = 1.8 or 0.8 Br = 0.5 or 0.5 (make this lower if there are convergence problems) Hc = 40 or 2.4 |

Re: LTspiceXVII symbol import problem:

Re: Ferrite Beads
Hello,
The lib and sym files under "Program" are not used by LTspice. The real directory used by LTspiceXVII is in the personal folder "Documents". If a symbol is copied in this path, it's shown in the component selection without setting an extra path. C:\Users\Helmut\Documents\LTspiceXVII\lib\sym? C:\Users\Helmut\Documents\LTspiceXVII\lib\sub Best regards, Helmut |

Re: LTspiceXVII symbol import problem:
AL D wrote:
"...even copied just the files to the sym directory. XVII refuses to see them." That's because XVII doesn't pick the symbols and models from "c:\Program Files\LTC\LTspiceXVII\lib\..." any more. Instead, on installation, a job is run that creates a directory in "My Documents" called LTspiceXVII and the whole lib structure is just copied there. LTspice then picks all live lib information from there. The same batch job is run when you do a sync update. I guess I can understand why this is done, but for me, it's a real pain. The reason for my annoyance was that because I am running IV and XVII side by side, I wanted to sync the lib folders in each, so I symlinked the one under IV to XVII. When I realised what was happening when I did an update, I cancelled the update without letting it finish. I kinda wish I hadn't, because it left my entire lib directory structure full of 0byte files. Fortunately, because I do practice what I preach, I was able to restore everything easily from SVN. Personally, I find the new method of library management in XVII really inconvenient, but probably because I went against "conventional wisdom" in the first place. When I work out how to make it work for me, I'll let you know. In the meantime, I've reverted to IV until I figure it out. Regards, Tony |

Re: LTspiceXVII released
I am a work now, so I can't check home, but C:\Users\[me]\AppData\Roaming is where the LTspiceIV.ini has always been.? I make an edited, generic back up copy to store my settings because I always feared that a fresh install would overwrite whatever was there.? Sure enough, now that I've checked, LTspiceXVII.ini is there, too.

I've had a problem at home with the ini file being trashed by during LTspiceXVII update attempts.? I can't remember where it is, though, without looking, which I can't do until later. ---In LTspice@..., <jmw1937@...> wrote : Analogspiceman says ?'

Re: Ferrite Beads
? ?"It looks like added symbols to the installation folders will not be shown in the component-menu." I guess you are saying this is only an LTspiceXVII problem? When I add symbols to the library folders, LTspiceIV does see them.? I have not tried that with LTspiceXVII. I guess that from now on, we need to be clear which LTspice program we are talking about. ?:-) Andy ? |

¿ªÔÆÌåÓýWe VERY often tell people that this is usually due to Windows protection of files in the Program Files folder. Put your own stuff in the same folder as your schematic, or in a 'My Library' folder outside Program Files. ? With best wishes DESIGN IT IN!
