Construction of a Dodecahedron
Some CAD software such as AutoCAD does not have all the geometric objects, in particular the famous Dodecahedron.
simple drawdown in descriptive geometry.
Step 1: Pentagon
Command polygon 5 faces, draw the bisectors,
Step 2: Plan folding
Construct their symmetric projection or command MIROIR ... With respect to the red axis and create point A.
Draw the penpendicular line on Z at A.
For the positioning of the angle of the projection of the bisector fold it on the perpendicular in Z (Cyan blue on the image)
Step 3: Alignment
Align the base pentagon with the new projected bisector (in magenta on the image). Command ALIGNER.
Build the other pentagons. RESEAUPOLAIRE commands (_-arraypolar)
Finish missing faces, several solutions, ALIGNER, MIROIR, COPY and ROTATE and mores...
For a better vision finish with command SURFACE you can EXTRUDE in SOLID too...
