Orthographic to isometric challenges
Read the front, top and side views. Build a solid from cubes that matches all three. There may be more than one valid construction.
The three given views
Solid edges can be seen; dashed edges are hidden. The floor buttons run from the back of the object to the front, just like the top view.
Build your answer
back
front
Tap the floor to start a stack. Each number is its height, up to four cubes.
Build freely, then check. A different solid is accepted if its three drawings match the given views.

How to turn orthographic views into an isometric object
Read the views together
The front gives width and height, the top gives width and depth, and the side gives depth and height. Use all three to decide where cubes can go.
Check hidden edges too
A solid can match the outline and still have a wrong step behind it. Compare the dashed lines as well as the outside shape.
More than one answer can work
The checker compares the three drawings of your construction with the given views. It accepts a different solid when all three views match. These exercises use stacks of cubes, up to four high.
