Week 9 - Project - Master Section Development

AIM: To create closed B pillar surface using given master sketch and A surface also creating b surface features like dog house and ribs

MASTER SECTION :

master sections are the guides that are required for shaping the component after technical styling of class a surface

TOOLING AXIS :

• Extract the sides of the given master sections
• create bisector line for these extracts
• then again use bisection for the 2 bisector line the obtained new line is the main tooling axis \
• rename it, change appearance and publish it

CLASS A SURFACE WITH FLANGE :

• check for any defects on the surface using boundary curve if there is any fix it
• then multi-extract the edges using tangency continuity (both sides of a surface )
• create a plane using the three-point method and select the points on the master section
• use the intersection curve and create an intersection of a surface on the plane
• sweep the multi-extracted curve and add this surface to the intersection tab
• try to align the sweep surface with the master section, do this step for both side
• now extrapolate both sweep surface and the class a surface and then trim them together

CLASS B SURFACE

• offset the given class A surface to a distance of 2 mm
• fix the surface if there appear any defects
• offset the flange created during class a surface at a distance of 2mm
• extrapolate the edges of both flanges and offseted class a surface and trim them together

CLASS C SURFACE

• Multi-extract the edges of the class a surface
• sweep them using draft direction as tooling axis
• keep the sweep angle at 3 degree
• trim them together

FINAL SURFACE

• Trim the class A surface with the class C surface and then trim it with the class B surface

• go to the part design and use closing surface and create a solid body out of the final trim

B SITE FEATURES :

DOG HOUSE :

• Extract the edge of the dog house master section
• place a point at the center of the extracted edge
• create a plane using the point and the zx plane
• create a positioned sketch and project the master section onto it
• delete the unnecessary parts and iso constraint it
• extrude the surface
• extract the limiting edge from other master sections and extrude it to
• trim it while keeping one side open
• create a new body and then add thickness to it
• offset the trimmed body with an offset of 1.2mm
• multi-extract the b surface under the dog house and offset it to 5mm
• trim both offset surface
• split the body with the trimmed surface
• add the required fillets

TOOLING AXIS FOR DOG HOUSE

• Create a line with direction on the point that we created earlier
• rename it to lifter axis and change the appearance
• publish the tooling axis

4 WAY LOCATOR

• Create a plane using the same point we created earlier and a reference plane
• make a positioned sketch on it
• project the required edges from the master section
• pad the sketch with 1.5 mm and neutral fiber
• union trim it with the dog house
• add chamfer to it
• add edge fillet to it

2ND 4WAY LOCATOR :

• copy the 4 way locator and paste it with links
• create a plane at the middle of the b surface
• use symmetry and create another 4 way locator
• union-trim it with the b surface body

RIBS :

• create a positioned sketch using the previously created point and plane
• create the first line with a distance of 60 mm from the axis
• create another line that is at a distance of 50 mm from the first line and at least 20 mm from b body edge
• create the remaining edges until the end
• extract the edges and then extrude them
• add the thickness of 0.8mm to it
• multi-extract the b surface faces and offset them at 10mm
• split the ribs with the offset surface
• draft the ribs with b surface
• do these steps for other side also
• add both using union trim

DRAFT ANALYSIS

MAIN TOOLING AXIS :

• USING ANALYSIS SELECT THE COMPASS AND PLACE IT ON THE TOOLING AXIS FIRST
• LOCK THE COMPASS AND THEN CLICK ON THE SURFACE

LIFTER AXIS :

• USING ANALYSIS SELECT THE COMPASS AND PLACE IT ON THE LIFTER AXIS FIRST
• LOCK THE COMPASS AND THEN CLICK ON THE SURFACE
