The look of construction drawings for film and television has changed a lot over the years, particularly now that most drawings are done digitally with computers rather than by hand.
While many current drawing styles now incorporate photo-textures, shadows, and icons to add life to drawings beyond what is typical of architectural drawings, it’s hard for them to match the aesthetics of hand drawings.

Having started as a pencil draftsman I guess I do have a bit of a personal bias, but the unique style of each person on a hand-drafted drawing was immediately recognizable to people who knew their work.
Before digital illustrations and renders of 3D models, hand-drafted drawings had to serve as a design sales tool as well as instructions for scenery construction.
Here are some shots of a set design by Erich Kettlehut in 1923 for the UFA film, Die Nibelungen, for the scene where Siegfried kills the dragon.
The drawing was displayed as part of an exhibition of artwork from the UFA silent film period of the 1920s and 30s at the Los Angeles County Museum of Art in 2014. The drawing is from the collection of La Cinématiquè Française in Paris, France.
Note that the drawing not only provides a pictorial description of what the dragon should look like, but calls out dimensions, construction materials, how the action prop is to be operated, surrounding scenery requirements, and specific technical details of mechanical movements.





Here are a few more hand-drafted pencil drawings from more recent films:
