  • Cool idea but not ready
    Clyde Clark | June 12, 2023 Verified Download (What's this?)

    As I am converting my business from Eagle to Fusion 360 Electronics, Ultra Librarian stuck out as a great innovation to help the transition. In practice, it is just not ready. 

    Launching Ultra Librarian is awkward because it is a tool in the schematic, not in the library manager or even library editor. So to add to a library, you need to open a schematic to get to UL, with some luck, download the part you need, and then go back to the desired library and hope it is there. Sadly, it usually isn't. 

    Installation is not ideal. First, you need to find the app store, which for some reason is not linked in any way I can find from Fusion 360. Then when downloading, Windows 10/11 is not happy about the file. So there is a lot of effort to install it due to lack of popularity and digital signature. Really, it seems weird that it needs to be installed locally at all for a cloud service CAD tool. So that means you need to go throuh all the effort on any machine where you want to use the "available everywhere" Fusion 360. Components can't be downloaded from their website, but only through the add-in from what I can find. 

    Then there is the quality of the library parts. The schematic symbols are not well done with lots of off-grid elements. The footprints often need some work especially on the paste layers. And the 3D cad are hit and miss along with having no file organizationi. In fairness, that is a Fusion 360 general deficiency. 

    As much as I want this to work, it just isn't worth the effort.
