Week 10 - Challenge 3 - Door Trim Lower with Engineering Features

Tooling axis creation :

• First I publish the class A surface then I try to find which method is suitable to create a tooling axis.
• In that given part bisecting method is not needed.
• So I simply create the point on the flat surface.
• Then create the line on the point by point and direction.
• And I perform the draft analysis with that line.
• It clear the draft so I rename the line into Tooling axis.

Draft analysis for class A surface :

• First change the view in to customize material mode.
• Then click the draft analysis select the compass and pick and drop on the tooling axis.
• And click on the surface.
• Change the draft value into 3deg.
• It clearing the draft analysis.

Class B surface creation :

• First I offset the class A surface 2.5mm, it create some patches.
• So I multiple extract the class A surface into 4 part.

• Then offset the extracts at 2.5mm.
• Create the boundary over the gaps then extrapolate the surfaces intersecting each other.
• Use trim command to trim the surfaces.

• Measure the fillet value in the class A surface.
• I extract the fillet edges and untrim the extract.
• Create the point on the edge then create a three point circle with point and vertex.
• Use the measure tool vernier to measure the radius.
• Then give the fillet value = Class A fillet value - thickness of the component.

Class C surface creation :

• First create a seperate boundary for which surface is parallel to the tooling axis and which surface is perpendicular to the tooling axis.
• Give the sweep with reference surface for pocket portion of 90deg.
• Use sweep with draft direction of 90deg draft angle for the surface is parallel to the tooling axis.
• Use sweep with draft direction of 3deg draft angle for the surface is perpendicular to the tooling axis.

• Some curve edges make problem.
• So I extract the A surface edge and connect edges of sweep by using spline.
• Use multisection surface to fill the gap.
• Click the edges of sweep as a section and click the spline and the extracted boundary as a guild curve.
• I trim the sweep of the sweep 1,2 and 3.
• Other sweep and multisection surfaces are connect with the Join command.
• We got the Class C surface.

Class A and C join and Final trim :

• First ensure both the surfaces intersect with each other.
• If that not intersect then extrapolate them to intersect.
• Then make a trim.

• And trim the Class A,C join and Class B.
• In my case some edges are intersect so I try to extrapolate it, but it doesn't work.
• So I use multisection surface to encounter the problem.
• Then make a final trim to get the closed surface.

Closed part creation :

• Insert a new part body to define that working object then change the name of closed body part.
• Jump into part design, click closed suface then select the surface.
• It make a solid component.

Heatstakes creation :

• Insert a new geometrical set and name it as heatstake.
• Create a ZX plane on the given input.
• Then create a position sketch on the plane.
• I create a seperate sketch for a circular portion and ribs.

• Then I insert a body and define a working object.
• And pad the circular portion and the rib separately at 20mm for heatstake boss and 10mm for heatstake rib.
• Then draft the rib and boss of 0.5deg of all faces.

• And give a required minimum fillet and chamfer.
• Copy the heatstake and use paste special as result with link feature.
• Then translate to move that to point to point translate.
• Copy that to move all points which are given in input.

4 way locater creation :

• Insert a new geometrical set and name it as 4 way locater.
• Create a new point on the required surface.
• Then create a plane on the point.
• Create a new sketch on the point.
• I give the length of the locater is 15mm.

• Insert a new body then pad the locater at 30mm.
• Then draft the all faces at 0.5deg.
• Give the minimum fillet and chamfer on the edges.
• Copy the locater and paste special as result with link to male separate solid.
• Then move that to required place by point to point translate.

Rib creation :

• Create a point on the surface wherever we need the rib.
• Create a sketch of rib in a new geometricalset.
• Insert a new body to pad the sketch of rib.
• Then draft the faces of 0.5deg.
• And create fillet and chamfer on the required place in rib.
• Copy the rib and paste special as result with link to create a separate solid component.
• Then move to where we want by translate option.
• I do one translate with point to point translate and coordinate type.

Draft analysis of closed surface component :

• First change the view in to customize material mode.
• Then click the draft analysis select the compass and pick and drop on the tooling axis.
• And click on the surface of the closed surface component.
• Change the draft value into 3deg.
• It clearing the draft analysis.

• Same the procedure for 4 way locater draft analysis but the value is 0.45deg.

• Below draft analysis for heatstakes.

• Draft analysis of ribs :
