Here's a couple courses where I use that approach: In this case I will set up a camera in a similar position as the art, set the render resolution to match the art, then set the art as the background of the camera. Sometimes you only have a 3/4 view piece of concept art (common for characters). However the situation can be different depending on the project. Very much like the shark sculpt in this course. The goal being to get it close, not perfect most of the time. Most often I will sculpt 'by eye' more than using modeling sheets. Over time you will get more comfortable though.

Unfortunately this is a more uncomfortable approach than ortho-centric modeling. IN the end it's always going to be viewed this way (never, or at least very rarely in orthographic). Therefore I highly recommend leaning more on perspective view over orthographic. So whenever we lean too heavily on orthos, the 'perspective' view (how our human eyes see) the model / sculpture tends to look off. While it would be convenient to sculpt in only ortho views, unfortunately 'orthographic' is not how our human eyes see.

As you say, chances are very low that symmetry will be perfect in 3/4 view art. In a practical sense, 3/4 views are always going to be less precise than orthographic views (front, side, top).

Greyscale: This option is similar to color, but outputs shapes in shades of grey instead of color.Hi valbuenajotace! First off, I sincerely appreciate your kind feedback 🙏.

Colors: This option produces multiple shapes based on color.

Brightness Steps: This option produces multiple shapes based on the brightness of the pixels.

The output will be a black and white image. Use the number of colors option to specify how many colors should be included in the shape.

Color quantization: This option uses colors to determine the shape.

The image output will be in black and white. Use the threshold box next to this option to increase the threshold to include more brighter shades in the image.

Edge Detection: This option uses the brightness of the pixels to determine if they should be part of the shape.

Use the threshold box next to this option to increase the threshold to include more shades.

Edge Cutoff: This option uses the shade of a pixel to determine if it should be traced as part of the shape.
