Hello, I would like to know how I do to make the kinds of spikes that there are on the 2nd image from the 1st? It's for a homework assignment and on the statement it is written "Hollow out the middle of the piece to allow it to be placed in position on the ministepper" but I never manage to get the right result.
You have to make a sketch on the top of the piece, then make the two arcs of a circle and the small pieces of the right that connect the two arcs of a circle using the "Convert entities" function (close the sketch by adding the two small pieces of the right). Then remove the material to the desired depth.
The expression "Hollow out the middle of the room" suggests that the shape is obtained by removing material. Step 1 : Select the plane of the top face of the part and create a sketch that is simply a rectangle. Use dimensioning or geometric relationships (collinear, coinciding, etc.) to constrain the geometry.
Step 2 : Use the "Extruded material removal" function, specifying the height of the removal.
Step 3 : The final result.
Another solution - more complex - was possible by adding material, with an extruded boss, then symmetry with respect to the vertical median plane.
