  1. You can see more multi-core usages almost anywhere, including those listed above, especially transiting from one view to another, entering/exiting editing modes, turning on hidden layers, changing view render mode, turning on multi-view, and now switching between sheet layers.

    Virtual Reality (VR) & (VRaugmented reality)

    I haven't done the experiments on this by myself. But this is another way to reduce motion sickness -- https://www.wired.com/2015/04/reduce-vr-sickness-just-add-virtual-nose/ But no matter what, I believe that motion sickness will still be there unless the headset has some optical magic implemented, something like this -- https://www.theverge.com/2017/12/20/16800474/magic-leap-one-creator-edition-augmented-reality-goggles-announce

    Multi View Panes Default to Split Vertically?

    @Pat Stanfordis correct. The ViewPane and splitter data are saved with the document. So you are able to save your templates with your preferred view pane configurations. But if you do not load from the template when creating a new file, it will create the default pane and splitter configurations. Chih-Pin
  4. Just for the record before we can provide the fix. If anyone runs into the similar issue in MultiView, please try turning on Unified View. This may solve some navigation issues (e.g. zooming) in perspective view with Unified View off.
  5. Hello line-weight, If possible, could you send the file to me so that I can take a look? Thank you so much!! Chih-Pin

    PIL (Python Image Library) for VW 2018

    Have you tried python -m pip install pillow? If successfully installed, you can see what version of pillow it tried to install.

    Hidden Line Rendering 20 min vs 3 Seconds

    Suggestion heard, I will raise discussions with my colleagues and bosses.

    Hidden Line Rendering 20 min vs 3 Seconds

    For instance, this is a fast HL mode on a cylinder - This is a standard HL rendering -- As you can see, the edges on both ends of the cylinder are missing in the fast HL rendering. There are also other similar cases to this. In my opinion, we need to at least make fast HL look the same (or at least similar) in these cases before we can make it as one of the render modes.

    Hidden Line Rendering 20 min vs 3 Seconds

    Sorry to disappoint you on this. But based on what I, as a software engineer, suffered when adding new features and fixing bugs in this complex system, I believe it's not possible to be that fast.

    Hidden Line Rendering 20 min vs 3 Seconds

    This is basically correct, except you will also see similar trick when you are flying over the views in design layer HL render mode. Without this trick, it can't achieve real-time interactive HL rendering. But after you finish flying over, it will try to calculate the full and standard HL render mode. I personally agree with these two suggestions. In many cases, the fast HL rendering is good enough, and it's much faster. However, I also see some improvements needed for fast HL rendering. I also suffered the unnecessarily long time HL rendering in my own personal projects. I will create a VE(s) and raise the discussions internally. Hopefully, we can have these features in VW.

    Hidden Line Rendering 20 min vs 3 Seconds

    There are two kinds of "hidden line" renderings in VW, "normal" hidden line and "fast" hidden line. If you hit "hidden line" rendering, it will give you "normal" hidden line, which goes through calculations line by line, face by face, test the distance between the camera and the actual lines. This produce "real line segments" that will give us many benefits, e.g. sketch rendering, highlight the lines behind objects in different representations, decide whether it needs to show highlight lines or not, and ready to export vector-based drawings. For the "fast" hidden line, you can find them in "Section/Elevation in-Place" editing mode. We are basically using an OpenGL trick to create similar effects. You will find some differences in between these two hidden line modes. This is fast, interactive, and real-time rendering almost without any wait. I guess OnShape uses this technique to render hidden line using WebGL in your browser instead of getting the actual "lines" from the server. You can read some more discussions in this thread - In my opinion, there are rooms for performance improvements in the "normal" hidden line mode in VW. For instance, we can show the "fast" hidden line first, and gradually pull the results from the normal hidden line to the view. I'm not sure how soon this can be done, but I'm sure there are some re-engineering tasks to do prior to it
  12. We do improve the stabilities of Best Performance overtime, even through service packs. This is one of our first priorities in terms of performance improvements.
  13. Hello Dubman, I tried to edit a standard symbol in a floating pane without crashing. So there might be something else that causes the problem. Would it be possible if you are able to attach the file or send it to me with steps to reproduce the problem if you prefer? Thank you so much!! Chih-Pin

    Cannot manipulate multiple view pane

    Hello RJDG, Could you send me the file if possible so that I can inspect the multiview data? You can choose to send it through the messaging system here on the forum. Thanks!! Chih-Pin

    2018 bug Rotated Plan View - No OpenGL

    Thank you!! This issue is addressed in the internal build and should be able to make it to the public later. Chih-Pin
