Week 10 - Challenge 2- Attachment Feature Creation (Dog House)
- The draft analysis is carried out on the given class A by using the command called featured draft analysis.At this stage we can analyse all the faces with the draft angle reference,if the draft angle is not sufficient we must proceed accordingly,In this case the draft angles was sufficient and proceded for the decision of tooling direction.
- For the given class A surface the tooling direction would be on the flat surface because the only CIRCULAR profile is having the flat surface .i have decided it to be the tooling direction on normal to the flat surface by creating the point first and line would be the axis of tooling.
- As soon as the creation of the tooling axis the offset surface will be taken from the class A and few fillets were not driven by the cass A and i worked on the fillets by using multiple extract and creating the boundaries,later extrapolation is occured to create the fillets by using fillet command.
- After following the same process for all the surfaces which are not carried over on the B surface from A will be done.
- The next would be creation of the surface C,with the draft by given angles,on the flat surfaces which is parallel to the tooling direction,and extrapolated to trim the final surfaces. finally join command is used to join the C abd A surfaces,and trimmed with the B surfaces.
- Checked the surfaces are closed properly by using boundary command,if i get the error message then it is a closed boundary,and applied the closed surface to get the solid body.
- Here the model is to be creayed with the dog house structure as it mentioned in the question,analyse the position of the given sketch on the referance surface,and created the plane perpendular to the tooling axis and created a sketch over it to create he structure of the dog house.gave the pad and shell command to get the required shape finally used the fillets to remove the shrap edges.
- The faces of the dog house also be drafted such a way that it is created the draft analysis,and reduce the rupture between the core and cavity faces,next step is the draft analysis must be carried out to check the solid,and due to the struture of the dog house,it is having shell in it,due to the shell it is going to create the undercuts with the referance to the main tooling axis,so we must clear the undercuts by using the side core,to ceate the side core we must create the side core axis which is created perpendicular to the main tooling axis and performed the draft analysis on the side core axis.
- The draft analysis is carried out on the solid surface on both core and cavity side wheather the solid is mouldable or not. All the images are attached below.
