    Evolve vs 3d Studio Max

    Hi Mark, Construction History, PolyNURBS, and real geometry are the three main points. All models made in Evolve can be used directly for manufacturing since it is actual surface and solid geometry rather than polygonal. Complete history gives the flexibility to edit/update features, dimensions, etc...without having to manually rebuild models. With PolyNURBS tools you have basically the same workflow and ease of concept modeling you find in products like 3d Max, but the big difference is that your models are NURBS based, can be used directly to create molds, tooling....and can be combine with traditional surface and solid modeling tools for increased control and precision modeling if needed. And obviously you have integrated rendering so no loss in visualization. Without knowing the companies process for producing products I can only assume they are sending out 3d Max models to be recreated in a CAD package in order to create models suitable for manufacturing. In this case there is usually some design elements that get lost in translation or inaccurately interpreted. By switching to Evolve it would give them more control over the products they are creating and also save them money in time and services needed for CAD support. Again this is all based on many assumptions. If you end up going with this company and are having difficulty convincing them to use Evolve you can contact me directly at chilton@altair.com. I'm sure we can arrange something to convince them and allow you to continue using Evolve. Thanks,

    Evolve 2018

    We will be offering both subscription and perpetual licensing.
  3. Hi Mark, What version of Evolve are you using, and are you on Windows or Mac?
  4. Sorry for the late reply. Just saw this open question. The MetaCurve will eventually be completely replaced by the Blend Curve as we add more and more features and options to it. As a result you will be able to achieve what you are looking for. And just some additional information regarding Class A surfacing. There is generally a lot of confusion about what what it is, what it means, and how to achieve it. There are "A" surfaces and "B" surfaces. "A" surfaces just means the visible/aesthetic side of the model, and "B" surfaces are the side of the model you can't see. Take a computer mouse for example: The exterior surfaces that you can see and touch are all "A" side surfaces, whereas the inside faces of those pieces are all "B" side surfaces. The confusion comes in when you start trying to define mathematically what Class A means. For every company and product the definition can be different. For some the definition can be as simple as tangential (G1) continuity as their minimum requirement, where others may require a minimum of curvature continuous (G2), or curvature continuous (G3). These are all technically Class A surfaces, but due to the automotive influence in the design culture most people associate Class A with G2 continuity or higher. But you also have to keep in mind that the higher the level of continuity the higher the chances are to introduce "wavy" surfaces because the modeler has to manage more and more points and their relationships to each other. So just because a surface is mathematically G3 doesn't necessarily mean it is the desired shape. There are a lot of things that I could get into on this, but I will leave it here for now. So can Evolve be used for Class A surfacing? Absolutely. We have customers all over the world doing this on a whole range of products. Our tools such as Loft, Sweep, Patch, Round, etc...all have options for G2 continuity. The only exception for Class A surfacing with Evolve would be automotive exterior stamped sheet-metal, which is a very special case where additional tools and control are needed and the Class A definition requirements are much higher. Hope that helps.

    任何有关Evolve 2018的消息?

    Unfortunately development for v2018 has taken much longer than anticipated in order to make the advancements needed. We are literally working day and night to get this completed as quickly as possible, but it is still too early to state a release date. I did state earlier that we will likely have subscription based licensing for the next version, but doesn't necessarily mean that we will not have other options. No decisions have been finalized at this point.

    Quiet forum

    Sorry for the lack of response here in the forums. We have not done a great job of monitoring and will be addressing this.

    Use of dimensions in Evolve

    If you are trying to change the location of the dimension text you can adjust it in the the modeling tool panel to the right. Not sure if that is what you are referring to.

    Evolve opens multiple instances of the program

    We don't currently support managing multiple files in one instance of Evolve.

    Edit point detached from line

    Sounds like a bug. If you attach the file we can have a look and get it fixed.

    Newbie questions

    To create a tangent line you can use the Tangent Snap.

    Evolve 2018

    There will be significant improvements to the drawing/2D layout tools in 2018. Our licensing will be changing to a subscription format in 2018. Compensation will be provided for anyone who purchased v2017 that wish to upgrade to v2018. I can't tell you exact numbers at this time, but I can say that it will be a better deal if you already have v2017.

    isolating a surface from projected lines

    When you apply the trim tool there is an option in the modeling tool panel for trimming perpendicular to surface. That should do what you are looking for.

    Version branching in Construction Tree

    Thanks for the feedback. We are always happy to hear suggestions. It's a great idea and I have added this to our list. Hopefully we can add this type of functionality in the near future. Thanks again,

    PolyNURBS objects

    We do allow all of these types of conditions, but as you said, you may create some issues with surface continuity, so it is best to avoid those wherever possible. Thanks,

    Snapping to quad

    Currently we don't have a snap option for this. It is on our to-do-list for the next version. Thanks,
