Continue to use your mdp_cup3_parting part.
Step 1 Only if needed, a staged assembly for this activity is in: .../ moldwizd/ cup3_3 /
Procedure to open the staged assembly, if needed:
Verify that no parts are open.
Verify that Application MoldWizard is active. Open mdp_cup3_top in .../moldwizd/cup3_3
Step 2 Create a patch block for the small circular opening in the conical wall of the cup.
If necessary, choose Tools. Choose Create Box.
In the Create Box dialog: Type:
ÏÏÏ ÏÏÏ ÏÏÏ ÏÏÏ
3
Select and confirm the cylindrical face of the small hole.
OK is not active until you have selected at least one face.
Choose OK to indicate you are finished selecting faces.
A block is created encompassing the volume of the face you selected.
Step 3 Trim the block to exactly fill the hole.
Choose Surface Split from the Tools dialog. Select and confirm the new block.
ÏÏÏ ÏÏÏ ÏÏÏ ÏÏÏ

NIf the Normal Indicator (N) points away from the volume
you want to keep (inside the hole), choose Trim or OK. If the indicator arrow were pointing the wrong way you would choose Flip Trim".
The cue line prompts again for a surface to split the solid.
Select and confirm the outer conical face of the cup.
Again, the indicator should be pointing in the correct direction.
Choose OK to trim the side indicated.
Select and confirm the inner conical face of the cup.
This time the indicator should be pointing outward, the wrong direction.
Choose Flip Trim to remove extra material inside the cup. Choose Cancel to exit from the Surface Split operation.
Note: Shading the view will make the solid visible.
How Does it Work?
Create Box creates a UDO (user defined object) and a sweep feature. Users of earlier releases of MoldWizard would have observed a single block feature. The UDO and sweep
combination provides full associativity between the patch block and the faces selected.

Surface Split trim sheets are created in Layer 255, or whatever is designated as MW_HideObjectLayer in the mold_defaults file.
Avoid making MW_HideObjectLayer visible or selectable. MoldWizard places certain objects that are displayed temporarily into the layer designated by the MW_HideObjectLayer setting.
TIP
Step 4 Patch the remaining rectangular opening.
In the MoldWizard Tools dialog choose Create Box.
When you use Create Box:
Be careful to pick enough faces to define
the volume you want. Two faces are sometimes enough; occasionally only one is required.
Be careful to pick any faces for which
associative update is desirable!
The system will create a block oriented
to the ACS that encloses the faces you select.
Extra" volume is determined by the
Tolerance setting in the Tools dialog.

Select and confirm the upper and lower faces, as shown
below, in the upper rectangular opening.
In the current example, the side faces do not sufficiently define the volume required, due to the curvature of the cup wall.

Again type Allowance . . . 0.125 Choose OK.
Choose Surface Split.
Select and confirm the new block as the solid to be split. One by one, select and accept six trim sheets:
the four sides of the opening
the inner and outer faces of the cup.
NOTE Remember to choose Flip Trim where necessary!

Step 5 Create Solid Patches.
Choose Solid Patch in the MoldWizard Tools dialog. Select the cup body as the target solid.
Select first one, then the other patch block as a tool solid. Choose OK after you select both patch blocks.
Cancel the MoldWizard Tools dialog.
How Does it Work?
As you select each tool solid, the system:
moves the body into MW_PartingPatchBodyLayer (25) creates an extract body
unites the extracted body to the target solid
If the product model changes, trim sheets update the original body. Then, extracted bodies update. The extracted bodies are united to the parting body, so it too updates.
It is up to you, the tool designer, to use an appropriate Boolean operation to compensate for geometry removed from the
product model by Solid Patch.
At a later step in the process the MoldWizard system will place a WAVE linked body" for each tool solid into the
MW_PartingPatchBodyLayer in both core and cavity parts. This automatic linking makes it easy for you to compensate the
material volume associatively. Typically, you will unite the copies to a tooling body in your choice of the core or cavity part.
