  1. need advice on modelling strategy/tools to use

    Once you trim to get the blue part, use surface offset with thickness enabled. Extrusion will not follow surface normals precisely.
  2. iMac Pro

    Ok I spoke to one of the developers and in a nut shell, Yes, the new iMac Pro will be faster in rendering. If you are primarily using Evolve for modeling, then the cost might outweigh the purported benefits.
  3. macOS High Sierra

    Hi Luna, We have tested 2017.2 and 2017.3 on Mac OS High Sierra. Please install the latest Evolve package from here
  4. We are kickstarting 2018 with a webinar hosted by Novedge. The webinar will give you a look at 2017 and upcoming 2018 release. Register today!
  5. iMac Pro

    Evolve uses Thea rendering engine for rendering(includes interactive rendering). Thea works best on NVIDIA CUDA supported cards. Thea's Presto render - a physically accurate rendering engine works only with CUDA technology. However, GPU is not fully utilized when modeling. The program relies more on your CPU and number of cores.
  6. iMac Pro

    Hi Lunau, iMacPro is a new device and we are yet to run a full test on the same. As we all know, Apple no longer supports NVIDIA cards and Evolve rendering works best on NVIDIA cards that support CUDA. If rendering is a major part of your workflow, this might not be good news for you. Currently, AMD A-series APUs support GPU acceleration in Photoshop but thats about it. From what I gathered, there is no GPU acceleration akin to CUDA, yet. AFAIK, there will be no significant speed improvement right off the bat in 2018.
  7. Class A surfacing is a methodology and modeling technique. Evolve contains some concepts of class A modeling like curvature continuity but is not the ideal tool for creating flawless surfaces, like those you see on automobiles. The inherent quality of class A surface is its ideal CV distribution. Certain tools in Evolve are based on parasolid(same engine as solidWorks) and deliver undesired CV distribution that can later be partially redistributed. Evolve has construction history, that makes it hard to redistribute points while maintaining dependencies. Most programs like Alias, leader in Class A surfacing, requires you to delete the history before manual manipulation of CVs. However, the nomenclature is slightly flawed. Everyone knows that to achieve a class A surface, the underlying curve must be of the highest quality. Therefore, your curves must contain the least number of CV's and show smooth curvature. See image attached. If you use the top curve to create surfaces, the output will be low quality. The bottom curve has a very close shape but with better CV distribution. Hence, while creating curves, use the curve plot tool - shortcut -SHFT+CTRL(CMD)+P and check the quality of the curve. For product design, class A surfacing is not a mandate, unless you are talking about Apple, that is very particular on surface quality. You can achieve good surface quality in Evolve at the expense of time.
  8. How to create solid bodies using loft feature?

    Starting 2016, the Trim tool accepts multiple input surfaces and curves. No need to combine the input bodies. Always check whether the body is a solid using Analyze - 'Tolerance check' tool. This helps avoid failures downstream.
  9. Rhino newcomer

    For wireframe resolution settings use CTRL+SHIFT+D and click custom. Here set the max and min to 1. To explode single lines and bodies. Use Edit - Collapse construction tree then separate entities. To explode combined lines and bodies. Use Edit - Collapse construction tree, then Uncombine bodies and then separate entities. To simplify curves, it must have no history. Use rebuild and simplify curve tools. To add segments together, use join curve entities. For surfaces, use combine. Can you please share the file causing the rendering issue? The problem is most likely due to bunched vertices after the revolve. One way to solve it is to not align the center vertices of the Rounded poly line along the revolve axis. Yes, this will create holes on the top and bottom which can be patched using 'Patch'. Once patched, use combine to add all the surfaces together into a single body and then assign material.
  10. Anyone using animation tool successfully?

    Hi, My sincere apologies for not getting back earlier. We are working on new animation tutorials for 2018. I have created a short video showing the basics of how to animate objects in Evolve. For more details on the animation panel and its detailed functionality, please refer to our help section. castor.mp4
  11. Create archway to support a freeform Surface

    Yes, it is tedious if there is no symmetry.
  12. Create archway to support a freeform Surface

    Hi, Apologies for the delayed response. Please let me know if the attached file is along the lines of what you are trying to design. structure.evo
  13. How to set up image planes?

    Hi Peter, We do not have an option to enable images in 3D viewport currently. The work around is to apply the image as a texture but this is only visible in interactive rendering mode.
  14. Hi Steve, You can delete all the objects in the scene except the cameras and save the file in 2016. Use File-Import/merge option to import this file into your new scene in 2017. The cameras will be added to your new scene. I suggest naming the cameras so that you don't have duplicates after merging.
  15. Wrap curve around Surface (Stretch tool alternative)

    Hi Nick, There are two tools to deform objects in Evolve that suit this use case and both options rely on a target surface. You have already found the stretch tool. The other is called surf-drape. In your example, the target surface is a lot smaller than the source curve. I am thinking this might be forcing Evolve to fit the source surface within the boundaries. To create a 3D curve, you can use the project curve option.
