Anything that you didn't trace or use tools like rulers, french curves to achieve is technically considered "freehand."
Technical drawing employs tools like T-squares and architect scales in order to produce detailed and technically accurate drawings of things like machine parts or Plumbing schematics. It demands absolute precision.
Freehand drawing, on the other hand, has a completely different set of priorities and objectives. It relies upon the more intuitive way of achieving proper (or desired) proportions ("eyeballing it")
A technical sketch maps out how something can either function or can be constructed. It is not the final stage of such a piece; however, a technical drawing is usually made precisely with specific tools to execute and communicate the end product clearly. A technical sketch is usually free-hand and is part of the first stages of planning out a technical drawing.
Drawing means any kind of sketching. It may be real (technical dimension) or imagination (no technical identification). where as, design means the sketch with technical data.
A technical drawing is drawn precisely to a scale. Measurements taken from the drawing can be scaled up to produce or build a full size structure or machine, etc. A freehand drawing could be a simple sketch, detailed drawing, rough doodle, of a subject and is classed as a picture.
a "flat sketch" or "technical sketch" is the blueprint for making a garment. it is a proportional drawing that details how a garment is constructed such as seam placement, type of seaming used as well as stitch placement and types of stitching used. a reference should be used to insure the proper drawing techniques are being used to identify types of detailing. rebecca
Sketch
I would say have a pen or pencil ready in use to draw something for your solution. technical problems
Artists use charcoal for drawing. The drawing is a charcoal drawing or sketch.
A pencil with a fine tip or a technical pen is typically used to sketch microscope drawings. These tools allow for precise lines and details to be captured accurately. Additionally, using a ruler or grid paper can help maintain correct proportions in the drawing.
That depends on what kind of sketches you are asking for? A sketch for engineering? A technical sketch? Or maybe an artistic sketch? There are many rules for technical sketches. There are different lines used for different purposes. The sketching for doors and window thickness, and miscellaneous are quite complicated. I suggest checking up some pdf files on the net or maybe borrow a book from the library.
Technical drawing looks like construction

It is known as a sketch - usually roughly drawn quickly.
