Week 9 - Attachment Feature Creation - Challenge 2

*CLASS A SURFACE:

a) Checked for open boundary of Class A Surface using Boundary tool, found no open boundary.

b) Publication done for Class A surface.

*MAIN TOOLING AXIS:

a) created a point on edge of Class A surface.

b) created a line at Y-Direction .

c) publication done.

*FEATURE DRAFT ANALYSIS:

a) checked for clearance of Draft on class A surface with 1.5 deg draft, found ok.

* CLASS B SURFACE:

a) created an offset of 2.5mm for class A.

b) Due to fillet surfaces, the offset for class B surface left with some patches and open boundries.

c) Tools used for clearing patches: Boundary, extrapolate,multisection surface ,spline,extract,multiple extract,projection,

join with merging distance 0.003mm, join with sub elements to remove,trim,split,sweep with explicit mode,etc.

d) after clearing patches with the help of above mentioned tools, checked for open boundaries in class B Surface, found No open boundary.

e) Publication done for class B surface.

* CLASS C SURFACE:

a) created a boundary for class A surface.

b) created Sweeps in line mode with referance to surface, Guide curve-Boundary 45, Referance surface- Class A, Angle-90 deg.

c) Joined all the sweeps with merging distance 0.003mm and obtained Class C surface.

d) Publication done for Class C surface.

* FINAL TRIM:

a) Joined Class A&C surface with 0.003mm merging distance.

b) Intersected Class A+C & B surface for complete Boundary.

c) Found some open boundary on class A+C & B surface, hence cleared it with Extrapolation.

d) Again checked for uninterrupted intersection, found ok.

e) Trimmed Class A+C & B Surface

f) publication done for SURFACE BODY.

* CLOSED BODY:

a) created a closed body for surface body with the help of close body tool.

b) publication done for closed Body.

c) checked for feature draft analysis at 1.5 deg draft found cleared.

* DOG HOUSE CREATION:

a) created a point on closed body surface w.r.t surface.

b) created a plane parallel to point.

c) created a sketch of dog house.

d) Extruded the sketch & joined it to the desired surface.

* DOG HOUSE parent BODY:

a) Thickened the surace by offset 2.5 mm.

* C-CUT CREATION:

a) extracted the required surfaces. & offsetted inward to 1mm

b) offsetted the above surface downwards uptill 3 to 6 mm height left from B surface.

c) trimmed all the surfaces to desired surface.

d) splitted the surface to avoid sink marks.

* SIDE CORE TOOLING AXIS:

a) created a line w.r.t dog house surface.

*DOG HOUSE parent body DRESS-UP FEATURES:

a) provided draft to inner surfaces of 0.5 w.r.t to side core tooling axis.

b) provided edge fillets of 3mm to outer edges & 0.5 mm to inner edges.

c) checked for feature draft analysis for clearing body with 0.45 deg, found all sufaces clear.

*CREATED PASTE SPECIAL BODY FOR DOG HOUSE 2:

a) created a point w.r.t surface on the closed body according to the picture provided in the challenge.

b) copied the dog house body and pasted it with paste special result with link on MAIN FATHER BODY.

c) translated the dog house with point to point translation.

*BOOLEAN OPERATION:

a) used ADD operation for closed body by defining the MAIN PART BODY.

b) used UNION TRIM for both dog houses by defining the CLOSED body
