It does not matter what plane you initially select to begin your sketch, however, once you've selected a plane you can begin creating the sketch.
There are many different tools that will help you create your sketch, many of which are geometricly based (which is why we advised breaking down your design into essential shapes). Some of the basic sketch functions are:
# Center Diameter circle (C); it does exactly what it seems like it would do, it creates a circle of a given diameter around a selected point # Line (L); it creates a line of a given length and angle # 2-point Rectangle (R); Creates a rectangle of a given length and width# 3-point arc; creates a arc based on 3 selected points # Circumscribed-polygon and inscribed-polygon; creates a polygon based on a given radius # Mirror; mirror a points or lines around a mirror line# circular pattern; creates a identical pattern that rotates around a given object # rectangular pattern; creates a identical pattern in rows and columns# sketch dimension (D); specifies a dimension eg. length of a line, angle between lines, etc. # offset (O); creates an outline of a selected sketch
As you add things to your sketch you are likely going to want things to change in a proportional manner, to make sure that occurs fusion has things called constraints. Constraints are based on geometric rules which will allow a sketch to change uniformly. some of the more commonly used constraints are:
# parallel: makes two lines parallel to each other # perpendicular: makes two line perpendicular to each other # coincident: placing one point onto another point, effectively making them into one point# equal: make two objects equal each other (I say objects as opposed to just lines because the equal constraint can also be used on things like angles) # construction: although not technically a constraint, it is used to remove an object from the sketch and make it a reference ( it is effectively like commenting out code).
There is many other constraints that can be used but often you don't have to manually select them because they will appear automatically. Some examples are the midpoint constraint, the mirror constraint, the offset constraint, polygon constraint, etc.
=== Basics (3-D ) ===
Once you've finished your sketch the next step would be to extrude it using the extrude function (E). Once you've extruded it you can manipulate it further, some common modification are:
# fillet (F): rounds an edge based on a given radius # chamfer: changes an edge to a bevelled edge , bevel being an edge that is not perpendicular to the face of said object. # shell: hollows out an object
===== Once you've finished modifying your sketch you can export it as a stl by going to Tools --> Make --> 3D print =====
