  • the information indicating the position / structure of one member is as follows: Information indicating the connection relationship with other members is not directly included. Therefore, if you change the dimensions and shape of one member, search the XYZ coordinates on the PC screen for the connection relationship with the surfaces, ridges, and vertices of other members around that member, and based on the results The position and structure of other members must be calculated and set again.
  • furniture components are usually processed in a number of shapes such as drilling, notching and grooving. If you design a three-dimensional CAD furniture component as a three-dimensional shape with holes, notches, grooving, etc., if you try to change the dimensions once designed, there will be little change in the dimensions. Even if it is a thing, it will have to reset all the dimensions of each structural member, and processing, such as drilling, a notch, and grooving, according to the dimension after a change. When the number of components of furniture is large, the work for that is enormous.
