Missing surfaces - they just disappear...

    Hi all,

    Okay, so I'm having a problem. I can deal with Alibre running slowly on my Ryzen 2700X BEAST (32 GB RAM, Zotac 2080, yeah life is good!). However, now whenever I perform certain actions like filleting or in this case, a revolve, faces and surfaces just disappear. When I export the file to an STL and view that file the missing surfaces do show up so they're still there, just not showing up on-screen. Any help? The 2080 is set as the default graphics card. You can see from the attached screenshots what happens when you move down the Design Explorer.

    I'm also using:
    Alibre Design™ Professional
    Version: 2018.2 64-bit [Build 19071]

    Thanks for any help. Its just really getting annoying.

    Try adjusting this setting. I think some people have had that solve similar problems.

    Thanks. Trying it, but so far no go. I'll keep fiddling with it, maybe close out and restart the program again.

    As Nate mentioned, applying a different facet resolution often fixes this - though in some cases the fix only lasts until the next session.

    There seem to be some cases where this is caused by very specific geometry and some limitations in ACIS kernel.

    Most of these problems should be fixed by the new rendering pipeline that will come with v2019.

    Make sure to try obvious things like update graphics drivers.

    If issue remains, you could send file to support for testing in a pre-release build of 2019.

    Thanks for all of the suggestions. The graphics driver is up to date; Nvidia updated it last night. I've also played with the settings again and no joy.

    Long-standing issue with Alibre. The next release is said to address this.

    try this one, when going and manually making the fillets. First get the constraint tangent set, and then dimension the angle, once you get that, you can delete the tangent constraint on one end of the fillet and change the angle by 0.1-0.5 degrees and regen everything and see if that fixes.

    Works for me but its hard to trouble shoot it and find which feature is the causing the offense that generates these missing surfaces

    Hi Bob,

    Is it possible for you to email me this file? If there are any booleans, please File > Package > Create Package. If not, just the ad_prt is fine.

    Well, the part might be too large for the email program to send it. Oh well.

    Can you upload it Dropbox or Onedrive or any other file sharing site and then email the link?

    I don't usually check that (support does but they won't know what to do with it) so pls email me when it's there and I'll go catch it.
