Week 9 - Attachment Feature Creation - Challenge 2

DRAFT ANALYSIS; THE DRAFT ANALYSIS COMMAND ENABLES YOU TO DETECT IT THE PART YOU DRAFTED WILL BE EASILY REMOVED. THIS TYPE OF ANALYSIS IS PERFORMED BASED ON COLOR RANGES IDENTIFYING ZONES ON THE ANALYZED ELEMENT WHERE THE DEVIATION FROM THE DRAFT DIRECTION AT ANY POINT CORRESPONDS TO SPECIFIED VALUES. EXTRUDE; THE EXTRUSION DEFINITION DIALOG BOX IS DISPLAYED . SELECT A SKETCH. BOUNDARY; THE SELECTED EDGE IS PROPAGATED AROUND THE ENTIRE SURFACE BOUNDARY. POINT CONTINUITY THE SELECTED EDGE IS PROPAGATED AROUND THE SURFACE BOUNDARY UNTIL A POINT DISCONTINUITY IS MET. TANGENT CONTINUNITY THE SELECTED EDGE IS PROPOGATED AROUND THE SURFACE BOUNDARY UNTIL A TANGENT DISCONTINUNITY IS MET. TRIM; IF GO FOR OTHE SIDE NEXT ELEMENT I WILL I CAN SWITCH THIS SIDE HERE OKAY AND OF COURSE ITS AUTOMATIC EXTRAPOLATED. SO THOSE SURFACES NEED NOT BE THE SAME SIZE. CLOSE SURFACE; THIS TASK SHOWS YOU HOW TO CREATE A SOLID BY CLOSING THE JOINED SURFACE. FOR THIS YOU MUST CALL UP THE CLOSE SURFACE DEFINITION DIALOG BOX. FILL; SELECT CURVES OR SURFACE EDGES TO FORM A CLOSED BOUNDARY. YOU CAN SELECT A SUPPORT SURFACE FOR EACH CURVE OR EDGES. IN THIS CASE CONTINUITY IS ASSURED BETWEEN THE FILL SURFACE AND SELECTED SUPPORT SURFACES. SCREW; IN THE DRAWING AREA SPECIFY THE INSERTION POINT FOR THE SCREW. ON THE COMMAND LINE SPECIFY THE ROTATION ANGLE OR PRESS ENTER TO ACCEPT THE DEFAULT. IN THE NORMAL DIAMETER DIALOG BOX SELECT THE SCREW SIZE AND THEN CLICK FINISH. IN THE DRAWING AREA DRAG TO SIZE THE SCREW AND THEN CLICK TO SET THE LENGTH. EXTRACT; THE EXTRACT DEFINITION DIALOG BOX IS DISPLAYED SELECT EDGE OR THE FACE OF AN ELEMENT. THE SELECTED ELEMENT IS HIGHLIGHTED. DOG HOUSE; DOG HOUSE IS AN ENGINEERING FEATURE USED IN PLASTIC DESIGN. DOG HOUSE ARE USED AS SUPPORT FEATURE. SOMETIMES OTHER ENGINEERING FEATURES LIKE SNAPS LOCATORS SCREW BOSSES ARE MOUNTED ON THEM TO INCREASE THEIR STRENGTH. DOG HOUSE ARE SUBJECTED TO DRAFT ANALYSIS TO PREVENT BREAKAGE OF THE COMPONENET DURING EJECTION FROM THE MOULD CAVVITY DOG HOUSE AND OTHER EMGINEERING COMPONENTS ARE BUILT ON THE B SURFACE. DOG HOUSE Creation; DOG HOUSES ARE DESIGNED TO AVOID SINK MARK CREATED ON THE CLASS A SURFACE BY SCREW BOSSES AND TO SOLVE THE LENGTHISSUES WHEN GIVING SCREW BOSSES WHICH NEED TO BE ASSEMBLED TO OTHER COMPONENTS. IT IS ALSO USEFUL WHEN PERPENDICULAR SCREW BOSSES ARE REQUIRED ON THE PART TO THE TOOLING DIRECTION.
