  2. Axonometric projection - Wikipedia

    en.wikipedia.org/wiki/Axonometric_projection

    In dimetric projection, the direction of viewing is such that two of the three axes of space appear equally foreshortened, of which the attendant scale and angles of presentation are determined according to the angle of viewing; the scale of the third direction is determined separately. Dimensional approximations are common in dimetric drawings.

  3. Technical illustration - Wikipedia

    en.wikipedia.org/wiki/Technical_illustration

    Technical illustration uses several basic mechanical drawing configurations called axonometric projection. These are: Parallel projections (oblique, planometric, isometric, dimetric, and trimetric), and; many types of perspective projections (with one, two, or three vanishing points).

  4. 3D projection - Wikipedia

    en.wikipedia.org/wiki/3D_projection

    On the flat drawing, two axes, x and z on the figure, are perpendicular and the length on these axes are drawn with a 1:1 scale; it is thus similar to the dimetric projections, although it is not an axonometric projection, as the third axis, here y, is drawn in diagonal, making an arbitrary angle with the x″ axis, usually 30 or 45°. The ...

    Chemical structures and reaction schemes should conform to the following: Images should be drawn with a molecule editor, never freehand; ACS settings should be used for both structures and reaction schemes. These settings are normally available as templates in chemical drawing programs. Use sans-serif fonts like Arial.

  7. Axonometry - Wikipedia

    en.wikipedia.org/wiki/Axonometry

    Axonometry is a graphical procedure belonging to descriptive geometry that generates a planar image of a three-dimensional object. The term "axonometry" means "to measure along axes", and indicates that the dimensions and scaling of the coordinate axes play a crucial role.

    Can automatically draw rings and other structures - has all standard amino acids and nucleic acids in a built-in library; Retrieval of structures from a network database based on CAS number, formula, or name; Retrieval of information on a molecule based on a drawing; Symbols such as partial charge and radicals

  9. Parallel projection - Wikipedia

    en.wikipedia.org/wiki/Parallel_projection

    In an oblique pictorial drawing, the displayed angles separating the coordinate axes as well as the foreshortening factors (scaling) are arbitrary. The distortion created thereby is usually attenuated by aligning one plane of the imaged object to be parallel with the plane of projection, creating a truly-formed, full-size image of the chosen plane.
