Generally speaking flat surfaces can have an even tone applied across them.Ĭurved surfaces however are a continuous face with no edge breaks for tone changes. Rendering curved surfaces is a bit different than rendering flat surfaces.

On a cube and cylindrical shape it looks like this. If you want to add a third mid-line weight apply it to any edges that may see partial light. The edges that don't see the light source will be the heaviest line weight. These lines will be drawn with the lightest line weight. To imply shadows and a light source with line weight consider what edges of your form are in direct contact with the light source.

This can be brought into focus by applying a heavier line weight to it than the overall form. Or you might want to call out a certain part of your figure like a feature or part. Varied line weight can also be used to emphasize or de-emphasize certain information on a page.įor example you can let structure lines fall back by using lighter marks to build your drawings and emphasize your final form with a thick line weight. When doing a quick sketch or orthographic drawing (straight on view front, back, sides, etc) I will often skip shadows and instead only use line weight to add dimension. Thin line weight and breaks in a line can be applied to give the impression of lighter areas or highlights. Line weight is a simple but powerful tool.ĭrawing tools are available in a variety of line weights.Ī thicker line weight can be used to imply shadow, ground the figure on the page or give an object visual weight. Shadows help add dimension to a figure, another way to make your drawing pop off the page is by varying your line weight.
