Features that are dimensioned using flexible dimensions typically include which of the following?

Flexible dimensions are particularly suited for features that are not strictly linear or defined by rigid geometric shapes. Curvilinear walks and planting beds often require adaptable dimensioning because their forms can be organic and flowing, making it essential for designers to convey accurate lengths and radii that may not conform to standard straight lines or angles. This allows for a more natural integration of these features into the overall landscape design.

In contrast, fixed walls and boundaries tend to be dimensioned using rigid dimensions because they have defined, unchanging elements. Property line markers also involve fixed points that are typically determined based on legal or survey data, necessitating precise and unyielding measurements. Structural elements often have strict requirements for dimensions due to building codes and engineering specifications, which require clear, inflexible dimensions to ensure safety and compliance. Thus, flexible dimensions are most beneficial in applications where adaptability and organic forms are present, reinforcing the appropriateness of curvilinear walks and planting beds as the correct choice.
