I have been able to import an environment and create realistic lighting rather quickly by using the power of GPU rendering. Paired with its ability to create instances of geometry, it makes it easy to render a megacity environment in half the time. One issue with this is the clutter that can be made with connecting nodes.
It is fully capable of all the design work you can give it. I have even designed houses with it. Turbo CAD Pro Platinum is all I have used for going on 3 years now. I don't know if other versions can do or can't do. If you are a graphic designer, you would need to port the files to a higher end program to manipulate the colors and renderings. For engineering and in-house work it is perfect.
Octane uses GPU rendering so it takes advantage of the video card.
It gives you a good selection of options to tweak and refine your model rendering.
It can use 3D instances so it doesn't overuse computer resources.
There are plugins that can be incorporated into other 3D packages for rendering.
Octane is particularly inexpensive compared to other 3D render packages.
You are able to copy certain sections of nodes in order to create different iterations of the same environment or model. For example, changing the lighting or camera features.
TurboCAD does all of the things we need it to do and some. The wide variety of options to create specificity in each of our projects is a large plus. The reason it was given a 9 is because the learning curve can be a little steep and sometimes certain processes are not as intuitive as they could be
Although both have their pros and cons, Octane is far less expensive and it allows for more control over the geometry within a scene with better lighting and camera controls.
TurboCAD is a well-priced solution for a small business, it comes standard with 3D modeling compared to DraftSight which does not. The user interface could be updated along with industry-standard shortcut keys but for the number of drawings we do, this package fills the gap. The DXF / DWG feature could be worked on too, as above, trying to get in line with other packages like AutoCAD & DraftSight would make the whole package better. All in all, I believe that TurboCAD has a valid foothold in the CAD industry.
