2D-prints and tactile images

3D prints are great, but

• it is not easy to make - or find - a good model (for tactile exploration)
• it takes long to print them

It is quicker and easier to make tactile images. Tactile drawing is a super addition or substitute.

Addition

A well made tactile image - or even a quick tactile sketch

• can help explore complex 3D-prints/maps/….
• may do in many cases (for ‘finetuning’/specifying when someone already has a basic mental representation)

Substitution

A well made tactile image - or even a quick tactile sketch will do, if:

• a reader knows the 2D to 3D method
• the object is not too complex

3D-models (reality/prints) are indispensable

• in the learning phase or
• when objects are very complex
