the image above shows the 4 phases that the cube gets subdivided with this algorithm

the reason why cubes is the best standard primitive when modeling a base mesh is that it gives you more flexibility to either subdivide it or retain it's sharp corners

Error Message: You Must Have Valid Objects Selected

When we get this error message, make sure "view" is selected in the render settings window. Also, make sure it is VRay and "Bucket" for type is selected. Forum Post: https://forums.autodesk.com/t5/3ds-max-forum/you-must-have-a-valid-object-selected/td-p/6242993

Fundamentals: Select and non-uniform scale

Select and non-uniform scale this icon selected, we can change location of edges when selecting edges of object Ex: We select both edge loops before the Select and non-uniform scale Before After Both edge loops selected and with select and non-uniform selected, we scale (r) to spread them apart equally

3DS Max - Edit Borders > Cap

Select edges switch to border mode go to edit borders and select "cap" -edges selected -switched to border mode and the "cap" option under edit border fills the gap. Super important when edges are all layered differently, or, this is how the software is reading it. Cap basically fills holes and is the most reliable option when improving the topology of your object.
