Week 9 - Project - Master Section Development
AIM: To create TOOLING AXIS, CLASS A, CLASS B, and CLASS C SURFACE and B side features by master section.
TOOLING AXIS
extract the master section lines.
create the bisecting lines between it.
CLASS B
offset the A surface.
improve the surface and create the boundary and smooth curve it.
use multisection
join the patch and offset B surface
class b surface
FLANGE
create a plan on multisection
create intersection of class b surface.
create multiple extract on the b surface
sweep the extract
offset the sweep
create spline on the sweep
join the patch
repeat it on the other side for flange 2
trim the class a surface with flanges
apply fillet to the flanges
repeat the same for class b surface and trim it with the flanges
CLASS C SURFACE
create multiple extracts and sweep them.
extrapolate the sweep
extrapolate the b surface
trim the extrapolated surface with the c surface.
final trim
now trim a surface with c surface
and b surface with the a and c surface
CLOSED SURFACE
B SIDE FEATURES
DOG HOUSE
crate a plan on the multisection
extract the master section and crate a point
insert sketch
exrapolate the sketch .
trim it
now thickness it
apply draft and fillet
4 WAY LOCATOR
insert a sketch and iso constrain it
pad it
apply chamfer and draft it
and fillet it
4 WAY LOCATOR WITH DOG HOUSE
AVOID SINK MARKS
RIBS
insert a sketch and draw lines with gape of 50mm
extract lines on the b side surface.
extrude each line
multiple ertract the base
and join it
offset the base
repeat the same on the other side
now thicken the extruded part
split itwith the base offseted
same repeat at the other side
now copy the part body of 4 way loactor with dog house and symmetry i on the other side
DRAFTING
It is a tool that allows the user to ‘see’ whether the part they are designing can be removed from the tool being used to make it. In the case of plastic injection molded parts it also allows the designer to see if there is enough draft on the part to ensure that it can be correctly grained. I always use the tool with the axis direction method. Put the main axis on the draft direction line with Z being parallel to it. Select the tool then select the part body. You may need to reposition the axis again. The results window has 2 options 1 with just 3 color variants and the other with many variants. They can be edited by double-clicking on them to give you the result you desire. The colors show the different draft angles
