I WANTS TO SPILIT TWO OR ONE VOLUME IN A WORKPIECE. CAN ANYBODY TELL ME ABOUT SHELLHOUTTE CURVE AND ITS OOPTIONS HOW TO MODIFY THIS CURVE AFTER DEFAULT CREATION (LIKE LOOP SELECTION, SLIDES.GAP CLOSURE AND DIRECTIONS .. PLZ SIR TELL ME HURRY . BCZ. I HAD FACE MANY TIME THIS PROBLEM IN INTERVIEW OFTEN.. PLEEEEEZ.
Shelhoutte curve is a curve formed on outline of a part when viewed in particular direction. I am not going to explain the entire core cavity split because we already discussed it in previous tutorial . Please go through following steps

Generally shelhoutte curve type of parting surface are used for splitting 3D shapped pipes, and components with full round edges. I took a simple plastic component with full round edge as shown in the image
Refer previous tutorial to assemle the component . else follow these steps
1-file-new-manufacturing then click mold cavity
2- Assemble the component as shown in the image
Once you assebled the component properly , you can click "silhoutte curve" and select the surface. You should select all the full round surfaces as shown in the image
Image shows the selected surfaces, for complicated components you need to define the direction plane also
Now you need to create a parting surface from the created silhoutte curve using sweep feature as shown in the image
You need to select that silhoutte curve and follow the steps as shown in the image and next you need to create a sketch (sweeping profile)
Just create a straight line of required length as shown in the image. We should keep in mind that this surface should cut the work piece which we will create in coming steps
Create a workpiece using automatic workpiece as shown in the image (you can also refer previous tutorial )
You can now do the core cavity splitting , Please refer previous tutorial for splitting core cavity
hey its gr8.......thanks a lot for this....
That was a good overview of the process. One additional item, make use of the "Draft Analysis" tool before even going into mold design process:
1. Select Draft Analysis and choose the model name in the model tree
2. Select a plane parallel to your parting plane
3. Turn off shading (ie, use hidden line mode) to see the part edges during the analysis
4. Review the part. Any surface that is colored "white" has 0 draft and needs to be fixed.
5. You are generally looking for a part with two color regions only. One side should be all blue (light and dark) and the other should be all red (light and dark). You should not have any "islands" of color. The border between the two colors is your parting edge.
Spending time reviewing with Draft analysis can save headaches in using the silhouette curve.
thanks, it helps me lot
