- Do draft analysis
Create tooling axis
1.Create tooling axis using the given master section.
2.Create a point on the master section.
3.Create planes on the given master sections with respect to the point created.
4.Using positioned sketch, create lines in the walls of dog house section and then create bisecting line.
5.Same way create sketch on the other side wall and then create bisecting line.
6.Using the bisecting line 1 and 2, create a new bisecting line which can be selected as the Tooling Axis.
Draft analysis of Class- A
1.After creating a tooling axis we do the draft analysis. Before drafting we have to make sure that in the view mode it is selected for the materials.
2.After selecting the feature draft analysis tool we drag the compass from its position to the tool axis. Then lock the compass. After that select anywhere on the component and it will give you the result.
3.We change the minimum draft for the component to 3°.
4.We can use the running point option to check the angle of the component.
Create B class surface
1.In the case of Class A the surface below is called core and the surface above is called cavity.
2.Class A is an aesthetics surface and class B is an engineering surface.
3.B surface should be inside the class A surface.
4.To create the class B surface, offset the class A surface inside as per our thickness requirement .
5.we can observe some patches on the offset surface by taking the boundary for the offset surface, those patches are formed due to the fillets on the class A surface. We need to cover those patches with the help of the multi-section surfaces command by extracting the patch boundaries
6.Once all the patches on the offset are covered properly join all the patches with the offset surface, to get the surface of the class B surface.
Create C class surface
1.I used the sweep command in the geometric shape design workbench to create the class C surface.
2.Initially, I extracted the edges of the class A surface with tangent continuity by using the boundry command.
3.After extracting the class A surface edges correctly, I sweeped the extracted edges with deg toward the class B surface.
4.Now I trimmed the extrapolated surfaces together to create a complete sweep surface towards the class B surface.
5.I joined both the trimmed sweep surface and class A surface together, to get the class A+C surfaces as a single surface.
Create closed surface
1.Check whether all the sides of class B and Class C surfaces are intersecting properly with each other, to get a closed surface by trimming class B and class C surfaces.
2.If the class B and class C sides are not intersected properly, we need to extrapolate the sides of the class B surface which are not intersecting with the class C surface.
3.Now, check class B and class C surface boundaries whether all the sides are intersecting or not with each other.
4.Once the surfaces are intersecting properly trim them together to get a closed surface
Create dog house
1.Create a point on the master section for plane
2.then take a dog house projection from master section by useing poject 3D element
3.after useing of this make a dog house and make side core axis
4. for inside surface 0.5 deg for draft , for outside surface 1.5 deg
A pillar
Do Draft analysis for close surface
1.First the following the below procedures.
2.By changing the view mode to custom view parameters - Material mode then the feature draft analysis is enabled.
3.Then the compass was activated and placed with the tooling axis by dragging the redpointer and then lockes it
4.Then, by selecting the quick analysis mode, the nominal value will be 3 degrees and checked for the component's draft angle
5.The green colour area shows that it satisfies the 3 degree draft angle
6.the faces which are highlighted in blue , red colour are not cleared properly with 3deg of draft angle
Do Draft analysis for dog house ( out side surface)
1.First the following the below procedures.
2.By changing the view mode to custom view parameters - Material mode then the feature draft analysis is enabled.
3.Then the compass was activated and placed with the tooling axis by dragging the redpointer and then lockes it
4.Then, by selecting the quick analysis mode, the nominal value will be 1.45 degrees and checked for the component's draft angle
5.The green colour area shows that it satisfies the 1.45 degree draft angle
6.the faces which are highlighted in blue , red colour are not cleared properly with 1.45deg of draft angle
Do Draft analysis for dog house ( in side surface)
1.First the following the below procedures.
2.By changing the view mode to custom view parameters - Material mode then the feature draft analysis is enabled.
3.Then the compass was activated and placed with the side core axis by dragging the redpointer and then lockes it
4.Then, by selecting the quick analysis mode, the nominal value will be 0.5 degrees and checked for the component's draft angle
5.The green colour area shows that it satisfies the 0.5 degree draft angle
6.the faces which are highlighted in blue , red colour are not cleared properly with 0.5deg of draft angle
Conclusion
Created the A pillar with dog house as per master section
