    Cutting in to a Solid Subtraction

    Interesting. I received a warning that I've never seen before saying the file was created in the student version and cannot be opened in the professional version. @JuanP is this new or maybe regionalized? I guess someone from NV will need to solve this thread since most of us won't be able to open the file.... Kevin

    Bot Z of symbol?

    Bruce, it would make more sense to consider the symbol as your "tile" not the geometry within it. Set all the geometry inside the symbol to Bot Z = 0" (relative to the symbol) and set the symbol "tile" to Bot Z = 1/2". (The only reason not to do this is if you anticipate moving the Z height of all the tiles later on since the easiest way to do it would be editing the symbol.) Kevin

    3D trouble shooting

    A file would help a lot. Some observations about what I'm seeing in your screen shot and a few things to try - You're working in a mix of 2d layer plane shapes and some 3d surfaces. The layer plane shapes have edges in your image, the true 3d shapes do not because draw edges is turned off. Are you drawing individual planes of your geometry like you would in a polygon modeller? Is Unified View turned on? You talk about moving from "any layer" to a "3d layer" which leads me to believe that you're working in 2d on some layers and 3d on others. Each layer will have a different view if Unified View is turned off. Screen Plane objects on different layers may disappear depending upon how your Unified View Options are set under the View menu. What happens if you try putting all of your geometry onto the same layer? If you take all of your geometry and paste it into a new file? Perhaps there's a corrupt object in your file. Pasting into a new file and then back again can often resolve things. What type of machine are you running Vectorworks on? Perhaps try adjusting your Navigation Graphics setting on the Display tab of the Vectorworks Preferences. Kevin

    Data Tags - Hanging Position Z value

    I did some testing and you should be able to use the Insertion Pt Z value found under Object Functions. It would be #IPZ# Kevin

    How to make a custom Data Tag

    Hi Matt, Have you tried using the Object Functions as the Data Source to pull from. There are options for Area and Bounding Box dimensions. Kevin

    Rendering Viewport turns everything black

    I wonder if its been previously filed as a bug. @Selin do you know? I can't really test and file it because I'm on a Mac. Kevin

    Rendering Viewport turns everything black

    When I open the file the cached viewport image has a black background. If I update the viewport it snaps to transparent as it should be. All of your settings are correct. This seems to indicate its not corruption in the file. I notice that you're working on a PC and I'm on a Mac. Out of curiosity what is your default compression set to in the Vectorworks Preference on the Edit tab? Kevin

    a "Real" 3D Polygon

    The subdivision tool creating hollow object in section is an issue. Hopefully this will be corrected in a future version. I miss Jim W right about now.... @Matt Panzer is there someone who can speak to this? Kevin

    Rendering Viewport turns everything black

    This example looks a lot like a Renderworks or HDRI background has been turned on. I don't think its the infamous "black viewport" issue in a traditional sense. Are you able to share an example file where this happens? We might be able to pinpoint the source. Kevin

    a "Real" 3D Polygon

    I just learned what a roof cricket is ūüėÄ I draw objects like this all the time using loci guides and NURBS. I would draw three NURBS curves (degree 1 creates straight sides), convert each to a NURBS surface and Stitch & Trim them together into a solid. It would be great to have a solids object that you could drag corner points around but it wouldn't be very easy to control until VW adds a 3d dragger type interface for point movement. Kevin

    How to draw a true ellipse

    Somewhere on the forums there is a "proof" of sorts that shows that within the margin of error from the calculations, a Vectorworks oval is an ellipse. There are issues if you offset an oval, since an offset oval is not an ellipse but Vectorworks draws it as one. Kevin

    need to create a solid from many many nurbs surfaces

    I think its probably a reference to using the Shell command to give the surface thickness. Without seeing the situation its hard to know exactly what to advise. I often create the extra surfaces needed (sides and a bottom surface) to make a nice clean solid and then run Stitch & Trim. Kevin

    Can't create a solid from NURBS

    Personally I would never move the user origin. I like the user origin and the internal origin to be the same. Its probably fine to do in newer versions of Vectorworks but in the past it could cause problems. Work in symbols? That would be a way to always edit objects near the origin, albeit the symbol origin. I tend to work this way but editing within symbols has been problematic in recent versions (seems better in VW2019 SP3.1). Sometimes with problem objects I will paste into a clean file, do my edits and then cut/paste back into my working file. Kevin

    Can't create a solid from NURBS

    Good catch with the origin. I tried the same method in place in the original file and couldn't get it to work. You solved the mystery. Kevin

    Can't create a solid from NURBS

    The issue here appears to be that some of the surfaces are 3D Polygons not NURBS surfaces. But on a bigger level there is something about this geometry that is preventing the solid you want to make. I tried various options without success. If I have time I may play with it a little more later. Kevin

    Rendering speed

    I bought mine refurbished from Apple. The price was more manageable and in line with the top end iMac. Kevin

    Rendering speed

    Are you rendering sheet layer viewports or in the design layers? Unfortunately my experience is similar to yours. I think that upgrading to an iMac Pro accentuates the bottlenecks in VW. Until the upgrades to the core components are complete (switching items to the VGM or removing single core bottlenecks like math/geometry calculations) I think it is what it is for more complex models.

    VW2019 - SP3.1? Are there release notes?

    Awesome! Thank you @JuanP. Kevin
  19. Vectorworks 2019 asked to update itself today to SP3.1. Does anyone know what SP3.1 addresses? Not sure who to ask now that Jim is gone...... Kevin

    UVW Unwrap

    You can convert the object to NURBS surface and use Model>3D Powerpack>Unfold Surfaces. Unfortunately it just piles all the pieces into a pile instead of arranging them logically. If you have access to Rhino, it has a much better unfold command called UnrollSrf with referencing and labels. Kevin

    Until Next Time

    @Jim Wilson this is unexpected news. I sincerely appreciate all of your hard work, support, and the advancements you've achieved over your years here. You will be greatly missed but you've set a great standard for your successors. Wishing you health, happiness and success for the future. Happy rendering, CNC'ing and 3d printing! Kevin

    Reducing LW of 3D objects

    If the lines in your example are indicating the surface curves, you can adjust the Hidden Line Render Setting for Smoothing Angle to control whether they appear or not. Not ideal, but it does give some control. Kevin
  23. I'd be curious to know myself. For years arcs behaved the same as your second example. A few versions ago it changed and now arcs extrude to wedge shaped solids. I've often wondered why they revert to a wireframe surface when the fill is set to none. Its like they partly maintained their old behaviour. @Jim Wilson do you know why this is? Kevin

    surface hatches not lining up with open GL

    I had this issue recently with an extrude. I was told by Tech Support that perimeter mapping isn't yet fully supported for surface hatches. As you discovered the solution is to switch to Auto-Align Plane. Kevin

    Creating Drape Surface not subtracting edges

    I'm not sure you'll get that draped NURBS surface to trim. Its quite complex and won't slice using the Split Tool which is a bad sign. The resulting drape ends up with a bit of an odd top edge too. I often make table cloths using the soft goods tool instead. I've attached an example file. The image below shows a comparison between the draped surface and a table skirt created with softgoods. If you draw and circle and use the "Create Objects from Shapes" menu command you can convert it to a Softgoods object. Kevin Table Using Soft Goods.vwx
