I think it was either products like this, or SolidWorks level tools if you wanted to do 3D solids. We ran circles around what anyone was doing with AutoCAD at the time. I started using it back in the late '90s when it (Vellum Solids) was added to Ashlar's 2D lineup (well, I suppose you could draw 3D, but it wasn't 3D solids, with solids tools). I can't speak too much to the current state of things, as I just re-upgraded my license after many years away (different career), but at one point, it was pretty competitive and had a really active community (so I assume it was relatively widely used, even if not by the big firms). If you lose too much of a stable user-base, then your resources diminish in keeping the project up-to-date (feature wise), or even support, etc. Then, smaller companies or individuals who don't need the certain features or compatibility, might use a better tool as their 'secret weapon' to be more productive and win some jobs.Īlso, when the big players like AutoDesk didn't have much in the way of competition for its predecessor - Ashlar's series (Vellum Solids, Argon, Xenon, Cobalt, etc.), or even into the Concepts Unlimited years - it was more popular (though never got too big, I suppose). It tends to be big companies using 'industry standard' products/tools, either because they need some particular feature, cross-company compatibility, or they just don't know better. I've seen this time and time again in various industries, especially with software. 10.13.x to 10.13.x will NEVER change a file system.First, keep in mind that the best products don't necessarily win. You could force APFS on a volume during a High Sierra install/in place upgrade by specifying -converttoapfs YES. Otherwise leave it alone.Īgain, the -ONLY- time when file system conversion is even an issue is during an INITIAL install/upgrade, and will only happen if the volume is electronic based, unless the install was started with -convertoapfs NO enabled. Flash/SSD volumes that are used strictly with Apple devices will benefit from APFS. (USB, SATA, Firewire etc.) Rather it is the medium. The method that the disk is mounted is not relevant to APFS optimal performance. Where as with a Finder Alias, (Symbolic Link) you can delete the actual file and have any aliases remain as broken links. If you have Hard Link entries, the data occupied by the file will -NOT- be recovered as long as any other Hard Links to that same data are present. Hard Links are a method of "aliasing" where there is more than one entry pointing to the same data in a file system. An APFS volume can absolutely be backed up/restored with Time Machine, The root cause being that APFS does not support Hard Links and that is how Time Machine organizes access to unique entries. Ever.Īs for Time Machine, the only issue there is that the Time Machine where the backups are placed can not be APFS. It does not ever do anything to any other volumes on the system. I have plenty of high Sierra installs on SSDs formatted GUID Partition Table / HFS Extended format. If the install is invoked manually using the terminal method it will -NOT- touch the file system.
