Tensile structures are often necessary compliments to rigid structures. There are many varieties of cord, knots, connectors, etc.
The use of cords in Replimat presents several challenges, such as the need to select the appropriate type of cord for a given application, and the need to learn and use different knots for securing and joining cords. To address these challenges, Replimat recommends the use of 550 paracord, as well as a simplified selection of knots for holding, sliding, and other purposes.

Replimat also encourages the development of cord looms, which are tools used to create cords by interlacing threads. Cord looms can be used to create a wide range of cords, from simple ropes to complex braids and patterns. The use of cord looms allows for greater creativity and flexibility in cord making, and can also improve the speed and efficiency of the process.

Tools: Cord looms

Introduction

String is a long flexible structure made from fibers twisted together into a single strand, or from multiple such strands which are in turn twisted together. String is used to tie, bind, or hang other objects. It is also used as a material to make things, such as textiles, and in arts and crafts. String is a simple tool, and its use by humans is known to have been developed tens of thousands of years ago. In Mesoamerica, for example, string was invented some 20,000 to 30,000 years ago, and was made by twisting plant fibers together. String may also be a component in other tools, and in devices as diverse as weapons, musical instruments, and toys.

Challenges

The use of cords in Replimat presents several challenges, such as the need to select the appropriate type of cord for a given application, and the need to learn and use different knots for securing and joining cords. To address these challenges, Replimat recommends the use of 550 paracord, as well as a simplified selection of knots for holding, sliding, and other purposes.

Approaches

Interoperability

Development targets

Replimat also encourages the development of cord looms, which are tools used to create cords by interlacing threads. Cord looms can be used to create a wide range of cords, from simple ropes to complex braids and patterns. The use of cord looms allows for greater creativity and flexibility in cord making, and can also improve the speed and efficiency of the process.
