Curvy3D GO

I've got the full version of Curvy 3D as well which is great, but I'm finding this smaller version easier to learn because it includes useful tool tips for all of the tools when you hover the mouse over them and is a simplified interface. I think this one will help me with the full version and it is great for making base meshes for sculpting in other programs as well (although it does also have basic sculpting functionality which is great).

TL;DR: Beginner friendly organic 3D modelling that's quick to learn. Only let down by no key rebind option.
Positives
+++ Extremely easy to use & understand. I'm an experienced 3D modeller and was right at home instantly, but I believe even beginners would also be up to speed quickly.
++ Great for very fast easy organic shapes.
+ Imports & Exports in OBJ for near universal compatibility with other 3D tools. Also imports SVGs, which is very useful.
+ Seems quite undemanding of hardware, so I'd be confident in running it on older hardware, maybe even laptops.
Negatives
--- Default keybinds are bad, counter to some common popular 3D programs, and there is no key rebind option! There is no excuse for this. ***Please add rebind key options for ALL keys AND mouse operations*** (Missing Rebind options almost made this review a negative)
- Less suitable for mechanical shapes, though not impossible (SVG import helps) but I doubt most modellers would use this tool for that purpose.
- As a fairly niche tool video tutorials are few and far between, although the few that exist to a decent enough job explaining the basics.
Summary
If you like modelling organic shapes quickly with minimum fuss in a quick to learn program then this is for you. I'd say it's ideal for beginners to organic 3D modelling (excluding the lack of key rebinds). For experienced 3D modellers it's likely the quickest, easiest organic shape maker available at this low price.
It's also a fun tool for creative play to just launch and draw something quickly.

So, I've been wanting to learn how to model in Blender for a long while but I could never get my head around modelling. With how simple Curvy3D GO looked I got it as an alternative. At first I was a bit stumped on how to use it but after following some tutorials I'm roughly a third or half-way there on my first human model. I'm still a bit unsure what to do here and there but I still made more headway than I ever did on Blender in years.
Granted given GO lacks rigging and texturing, something the main Curvy3D programs have, you can still import your models as .obj which Blender will gladly take. (Ironic how I have basic understanding of rigging and texturing in Blender but not how to make models.) therefore you can make characters or objects on Curvy3D GO with ease and put the finishing touches on them on Blender.
This seems almost too good to be true as a model-making program for beginners. I imagine the reason why Curvy3D isn't a renown is because they're expensive while Blender is free. But Curvy3D GO is cheap (£3.99, though I recommend waiting for the 50% off on sales), mostly purposed for teaching Curvy3D with all the necessities in making models. I'm just saying if someone like me can figure out how to use it, imagine what someone decent at Blender could do duel-wielding these programs!

I own 2, 3 & 4 with over 600 hours invested collectively and have supplied Steam's workshop with two little useful guides for this app. Unfortunately none of versions were ever properly completed to stability and had to be jumped back and forth between, collectively, to finish a project.
Prior until now I've been recommending this software all over the place but the long and ongoing development for 4.1 from EA concerns me for more casual users whom may not want a pipeline of both 4.1 and GO on top of having to learn and understand both programs limits and glitches while exporting your files back and forth between the two; especially when it comes to losing unsaved progress from a crash drop for using a tool or function that still requires a patch or two or because Copy/Paste Mirrored objects have to be formatted opposite their current form (Normal or Adaptive) before said function is executed leaving an copy with all of it's norms inside out, while overlapping yet a new lathe, and thereby negligible to healthy runtimes.
I would hold out on buying 4.1 which is taking a very long time to release as 5 is currently being developed simultaneously.
I would get GO until until either 4 or 5 are out of Early Access as you're mostly only missing the texture painting and depth mapping features which can be handled by 2D apps like GIMP, Corel Paint, Dogwaffle, Krita, etc.
There are some other features in 4 like Bezier curves and a more focused Boning feature (posing can still be done via masks) but, once again, bugs still in the software disable some of these extras anyway.
So go GO and keep your eyes peeled - Who knows, 5 may be completed soon while 4 is left to die in it's EA state. =)

Really diggin this awesome Program . Lightweight, and has a low learning curve . Excited to see more updates and features being developed .

not bad actually but I want you as a request to add normal modeling In this program like blender not only sketch and sculpting

So awesome, very very cool, I have a lot of ideas now. thank you!!
