Question: What French man did technical drawings of a buildings?

Context paragraphs:
ISO 128: ISO 128 is an international standard (ISO), about the general principles of presentation in technical drawings, specifically the graphical representation of objects on technical drawings.

Technical illustration: Technical Illustration is the use of illustration to visually communicate information of a technical nature.  Technical illustrations can be components of technical drawings or diagrams. Technical illustrations in general aim "to generate expressive images that effectively convey certain information via the visual channel to the human observer".

Drafter: A drafter, draughtsman (British English) or draftsman, drafting technician (American English and Canadian English) is a person who makes detailed technical drawings or plans for machinery, buildings, electronics, infrastructure, sections, etc.  Drafters use software and manual sketches to convert the designs, plans, and layouts of engineers and architects into a set of technical drawings.  Drafters operate as the supporting developers and sketch engineering designs and drawings from preliminary design concepts.

Architectural drawing: An architectural drawing or architect's drawing is a technical drawing of a building (or building project) that falls within the definition of architecture.  Architectural drawings are used by architects and others for a number of purposes: to develop a design idea into a coherent proposal, to communicate ideas and concepts, to convince clients of the merits of a design, to enable a building contractor to construct it, as a record of the completed work, and to make a record of a building that already exists.

Charles-Louis Balzac: Charles-Louis Balzac (1752 – 1820) was a French architect and architectural draughtsman.

ISO 7200: ISO 7200, titled Technical product documentation - Data fields in title blocks and document headers, is an international technical standard defined by ISO which describes title block formats to be used in technical drawings.

Architectural reprography: Architectural reprography, the reprography of architectural drawings, covers a variety of technologies, media, and supports typically used to make multiple copies of original technical drawings and related records created by architects, landscape architects, engineers, surveyors, mapmakers and other professionals in building and engineering trades.

Drafting linen: From the late 19th century until the middle of the 20th century, drafting linen, also known as drafting cloth, was commonly used as an alternative to wood-pulp and rag papers in creating technical drawings. Its major benefits were considerable strength, especially in erasing and redrawing, durability in handling, and translucency for making multiple reprographic prints.  Manufactured as an undyed muslin woven fabric, typically using cotton or linen fiber, the textile was highly starched and then calendered to create a smooth surface for precise ink and graphite lines.  Although drafting linen was most typically used in creating original drawings, it was occasionally used as the underlying support for blueprints and other similar reprographic processes.  Drafting linen largely fell out of favor after the development of drafting film — varying in chemical composition from cellulose acetate to polyester—in the 1950s.

Technical pen: A technical pen is a specialized instrument used by an engineer, architect, or drafter to make lines of constant width for architectural, engineering, or technical drawings. "Rapidograph" is a trademarked name for one type of technical pen.  Technical pens use either a refillable ink reservoir (Isograph version) or a replaceable ink cartridge.

Drafting film: Drafting film is a sturdier and more dimensionally stable substitute for drafting paper sometimes used for technical drawings, especially architectural drawings, and for art layout drawings, replacing drafting linen for these purposes.  Nowadays it is almost invariably made of transparent biaxially oriented polyethylene terephthalate, which should last several centuries under normal storage conditions, with one or two translucent matte surfaces provided by a coating.  However, some older drafting films are cellulose acetate, which degrades in only a few decades due to the vinegar syndrome.  Uncoated films are preferred for archival, because there is then no possibility that the coating material could deteriorate over time or react with other materials.
