The chair conformation is the most stable conformer. At 298 K (25 °C), 99.99% of all molecules in a cyclohexane solution adopt this conformation. The symmetry group is D 3d. All carbon centers are equivalent.

The chair conformation minimizes both angle strain and torsional strain by having all carbon-carbon bonds at 110.9° and all hydrogens staggered from one another. [2] The conformational changes that occur in a cyclohexane ring flip take place over several stages. Structure D (10.8 kcal/mol) is the highest energy transition state of the process.
A is thus the most stable conformation &, of all the other conformations, occurs most often in room temperature. Valleys A & B are local energy minima & A is global minima. A & B can thus be classified as conformers.
In addition, cyclohexane conformations can be used to indicate if the molecule has any 1,3 diaxial-interactions which are steric interactions between axial substituents on the 1,3, and 5 carbons.

November 2017: Cura Connect was released to enable users to control, monitor, and configure a group of network-enabled 3D printers from a single interface. [12] October 2018: Beginning with version 3.5, all files are saved in the 3MF format for improved compatibility with other 3D software. Hotkeys were introduced as well as a searchable ...
