    Hi Francesco. Thanks again for your answer. As I said I see a great potentioal in this application and understand you have an absolutely new product to come in the next version. So I will be waiting for it with anticipation and hope! I forgot to sent the post I made yesterday, so it is below. Maybe you shouldnt bother unswering if lots of things will change in next version. Bet nevertheless I leave the post as I wrote it. Thanks again for your hope and kind answers! Hello guys! Was trying to find but most likely there is no such a setting. I don't want to see any isoparms. They really make a mess in a wireframe view and it is hard to see the edges. Also it would be good to have individual settings for edges and isoparm colors. But it seems you can turn it off only in shaded view. Look at the screenshot. Do you think it is comfortable to percept this view and clearly see the edges? For me it is really a mess, no clear picture, especially when you don’t see any objects. To find a requited profile there which corresponds to the shape is a challenge. Only in the World browser which is also not very much informative. So I distribute objects to layers - all solids/surfaces in 3D layer, important original curves taht correspond to the shape into shape layers, other dependant curves made of original ones into curve layer, or smth like that. Then, why the center of this revolved object below looks as if it was modeled with triagonal poligons convergin in a "star" point? How to solve it out? Then I am having difficulties with lines. I cannot explode lines into segments to simplify some of them. The application treats it as a single line (therefore it is sort of a polyline that consists of segments). And I cannot split it into segments. Neither can I collapse the construction tree, nor can I uncombine entities. What is the process of simplifying curves? Say when my straight segment consists not from 2 but from 20 nodes? Yes, I can divide the curve with corresponding tool, then collapse the construction tree, simplify segments and join it again, and then collapse the stack. Not sure if it is correct, too much actions, but see no options. Then I want to join that manually split 20 segments and I have to add it one by one without the ability to select them all with the selection window. Very weird. Also, I found no points drawing. Sometimes they are helpful, don't know why they are not here. When smth fails to be created you nevertheless get the blank item in the world browser. Why does it necessary for empty objects? I am very much used to first select entities, then perform any operations. Most of applications allow you to do first change and then run command, or vise-versa. I really want to get the hand in this application, I think I got to know most of the features for this week of trying. But there is really lack of information, whatever you Google in the internet you end up with only help link. Looks as if it was just developed so few info on that. A Hybrid modeling is a perfect tool for me, I really dreamt of such an application while switching front and back between bunch of 3D software. At one moment I thought that I found the perfect one, but I think I have to high expectations. For now, I think I will have to put it away but I will keep an eye on 2018 and will be waiting for it with a huge hope.

    Evolve vs Rhino

    I got interesed in this software because I love parametric modeling (started with it on Autodesk Mechanical Desktop). In my job I use Rhino in 80% times and 10% Solidworks for special cases or just for filleting purpose at which Rhino fails and 10% 3D max for complex non-industrial polygonal modeling (consider its polygonal tools the best I've seen. This is how the Polynurbs has to be someday ). I need more "design as you go", so Solidworks is not my choice for everyday's use, therefore for industrial design it is perfect. So I decided to give a try on Fusion 360, which is quite impressive, also has T-splines (so far simplified version, but Rhino 6 stopped using it at all) but again it is quite hard comparing to Rhino - where you can move around 10 times faster but has no chances to change smth in some cases and Rhino is really patheric with regards to filleting. So a hybrid modeling is a perfect thing, but after 1.5 weeks of learning Solidthinking my thought are that this is sort of a beta version. Powerful but with lots of simple and needed tools missing. Lack of osnaps, not possible to turn off isoparms in wireframe turning the model into a mess, artifacts on revolved cylindrical models on flat caps (as if it was done by poligons converging at one point), no selection tool apart crossing one (in 90% I need non-crossing selection window), no chances to scale or move with reference points (say you pick first ref point – you can do it here by moving pivot point, then take second ref point of the model to scale and the target point – not possible), really messy world browser, no constains at all (parallel, coincidence, perpendicularity, verticality - I think if you call your software parametric moldeing software there must be constrains, which are the basics of parametrical model), quite weak mapping tools, very-very limited sub-div tools, lack of information and good tutorials in the internet etc etc etc... So I wouldn’t consider your software as Ferrari and Rhino as Prius, sorry but for Ferrari level you need to implement and improve a lot of things. I cannot work with it so far, it slows the workflow down comparing to Rhino, and I am saying that after having worked 2 weeks and getting to know its main features. Rhino is a great application missing construction tree. Therefore, it has history, but it is easily broken. In 80% you can change things with direct modeling moving, edges or even vertexes. As for the Solidthinking I love its principle, I love that you can make subdiv (Polynurbs) and combine it with nurbs - this is perfect but not new of cause. I am sorry for my strong criticism, but this is because I really like the application and want it to become better, so one day it will substitute all application I use. I notice that even I have made my decision, I keep coming to play with Solidthinking more. So I will be really eager to see the new 2018 version and hope it will be more advanced and efficient application!

    Hello Francesco! Thank you for your reply. You have answered some of my questions but I would like to clarify some points and appreciate if you would be able to answer them! 1. Example. I drew a circle somewhere. Now I can move it to 0,0,0 world coordinate with use of the translate command. Changing world/local axis changes only the location of the pivot point of this circle. I am happy with it to be where it is but I want to move it TO 0,0,0 world. Now the fields of TO X,Y,Z show only the relative change of the translation coordinate, not the absolute world coordinate which I want. Or maybe I am missing smth? In Rhino I assign the 0,0,0 Absolut coordinate to a shortcut. So I run move (translate) command, pick ref point of the subject (circle's center with osnap) and press a shortcut. Very easy and fast. Here I am really missing that I cannot pick ref point on the subject to be moved. Say quadrant. 2. This is really I can't understand. Say, there is a sweep feature, and undersees a profile. I want to select it but I cannot see it so I don’t know where to click. The easiest way is to select it with a non-crossing frame. What I have to do here - select it (will select all) and then start to deselect other things with the same crossing frame. Can you imagine how many clicks I have to perform if the desired profile is surrounded by many objects? At lease 4 - over it, under it, left and right. I think it is primitive but MUST have instrument. Furthermore, when I try to combine objects - the crossing section just doesn’t work - it pops up with the particular item to select from. It wants me to select items one by one but why? Why cannot I cross select items I want to combine, what tech process/algorithm it violates? 3. Yes, layers are what I use to distribute items in Rhino and keep them organized. Will do here as well, because World tree is not smth what is associates with world organize to me And I am missing features such as - copy object to layer (Rhino). Now I have to make a copy/instance and then manually drag it to the new layer. Would be much easier with copy to layer feature (an in options I would add - copy to layer as an instance or a copy) 4. Thanks 5. UV follows isoparms, but it doesn't mean I want to map it accordingly. I didn’t spend much time on it and will have to check more. Thanks. 6. Not sure. I see when I select the set of edges the scale axis doesn’t change for approximated normal direction. It scales it down to flat polygons in not desired direction. Face select seems to orient the axis correctly, but with few of them selected again the direction seems to be wrong. As for the other instruments for Polynurbs. I agree, 3D max is a top pro and polymodeling is its main purpose. I don’t consider it as solid modeling app, or nurbs (it has it but to just consider it is just there). But take a look at Rhino's T-splines. Not as what they turn it in the Fusion 360, but in Rhino 5. They are a way more flexible and powerful. I really took a huge interest to Solidthinking for this superb combination of poly+nurbs modeling. At what I see polynurbs features here is really week, but I do hope you will develop it to more powerful and precise instrument in future! Really wish you luck!

    Hello there! At once want to apologies for many words and too many comparations / whishes. My story. For many years I’ve been working in several applications such as Rhino with T-splines, if required – SolidWroks and standalone renderer Keyshot. On the one hand, I like Rhino for its super-fast workflow, flexibility and power, on the other – I hate it for its fillets/chamfers really pathetic abilities with huge restrictions – so it is much faster to throw a model into SolidWorks and do any fillets (you call it rounds here) and then export it back. Also, I loved Rhino for T-splines. Indeed, this is not 3D Max which I find a king of poly-modeling with super-duper convenient tools which I have never seen in other applications but… what really attracted my attention in Solidthinkin is a hybrid modeling, so you can combine polynurbs with other operations, other nurbs tool and always be able to go back to polynurb and edit it. Make a base shape from polynurbs, trim it, cut holes in it without having to think about topology, brilliant! I like the sort of parametric modeling techniques in the application. Actually, it is smth in between of SolidWork browser and 3D Max stack tree. But I like it. Also, the interface looks as Rhino, uses some similar curve and surface tools and I thought I would get a hand in it quite fast. But having played around with it for a few days I have a bunch of questions. I am really at stupor at some of them and not sure I am ready to leave Rhino for keeps in favor of ST (SolidThinking). Why there is no absolute coordinate input in Translate properties? Only relative one. You can only change the pivot point location relatively world axes but not the object Selection window has ONLY crossing effect?? I spent 2 hours searching in the Internet to find how to make the boundary selection (non-crossing). Max has a switch, Autocad / Rhino – depending on the angle where you start it. I just can’t imagine it doesn’t have it! I’d rather be with non-crossing selection – would be easier. I will not explain why I need it, I think it is very much clear that in most of the case you don’t want it to be crossing. Ctrl+alt+selection has some strange effect but it is not it. World tree. Maybe it is a matter of habit but I find it really hard to work with. A mix of all possible uninformative object names. Could you maybe at least make a different icons for surface, curves, solids etc so it would be easier to navigate through? SolidWorks has a really nice and clean tree. In ST it is a mind blower for me. Maybe it is a lack of practice, but when I first run SW it was all clear to me. Here it takes time to understand. Sometimes when I hide smth I have difficulties to find it in the tree to unhide. Fillets (rounds). Works fine but why can’t you add interactive radius? Now you only can type it. Not interactive at all. Texturing. Where is UVW? Where is UVW unwrap? Is it possible to work without it to make texture mapping for complex surfaces the way a user wants? Polynurbs – was really my hope since Rhino 6 supports T-splines no more, Fusion 360 is really limited and not flexible. And I am really missing some features Weld. Why only boundaries? Weld and target weld is a main principle of polygonal modeling, of retopology (3D max, Rhino T-splines, Fusion, Blender, Cinema4D – all have it!)a. And you propose to delete entire face to free up the edges and then weld it? And what if I want to weld only the upper vertexes of the face and leave bottom one intact? Delete a face, weld upper vertexes and append a new face that I have to build/close hole? This is really a huge question for me. No grid snap when extruding faces, sliding edges? Snaps works only when translating them, But I want to extrude with snap – have to extrude, then go to translate and snap, then again go to extrude and again snap. Either pls make it snap, or maybe add the ability to shift+translate = extrude/copy as in many applications. No edge constrains. Related to this 3D max is super precise in mater of retopology, you can move vertexes around with edges restrictions! Here you have to either draw a a helper nurbs-line to snap to it, or make it on sight, roughly. Why no snap to edges? It could be sort of edge move restriction. Do you know such a feature as flatten vertexes? It approximates a selection of vertexes into a flat surface. If the pivot point and local coordinate could adjust to the selection normal it would be possible, but it can’t so I see no other options Chamfers. In polygonal modeling you very often want the ability to delete edge loops, that is why the correct chamfer is the one that doesn’t remove the edge – it has it but just adds 2 extra loops adjacent to it. So in case you want to remove the chamfer – you select these loops and delete them, leaving the corner as it was originally. What do you do if you want to remove a chamfer with 2 edges, with corner edge gone? You have a headache. You will lose your shape! Rhino, Max and other apps has the option to “keep the face”, so the original edge remains where it was. I really want it here! backface culling/ignore backfacing - I want to be able to have the ability not to select vertexes that are on the back faces. Again - standard feature. keep shape when inserting an edge loop - enable/dsiable the automatic shape adjustment when inserting a loop, so it remains the shape in subdiv mode and the shape is different in low-poly mode. Well, that’s it for the moment. I am sure I might continue but this is the main points I can’t understand. Maybe in some of them there are solutions or instruments to cope with, so I am sorry than. Just as I said I’ve been working with Solidthinking for a few days. It has a huge potential and I think Iif I could find the answers to above questions I would move to it for keeps! PS. It has a really cool renderer! Not Keyshot/Vray but still very-very nice and can be used in most of the cases!
