The Subassembly dialog box opens.
Select TUTOR_SHARED from the Subassembly pull-down list.
Enter TUTOR_RUNNER into the Name input panel.
Click OK to leave the Subassembly dialog box.
A new EMX Subassembly will be added to the mold base assembly.
Open the TUTOR_SHARED.ASM assembly.

Create the Runner Quilt Surface

Activate the TUTOR_RUNNER.ASM assembly.
Create a assembly dependent Copy Geometry feature which contains:
- The coordinate system CSYS_RUNNER from the ARTICLE_REF.PRT
- The relevant quilt surfaces from the article reference part. (You must be Show the Layer 00_BUW_DATUM for catch it)
Open the TUTOR_RUNNER.ASM assembly.
Make quilt surfaces are not hidden by layers.

Assemble the Conic Gate

Activate the TUTOR_RUNNER.ASM assembly.
Click EMX Components ▶ Library ▶ Assemble.
The Library Component dialog box opens.
Select runner folder from the library tree.
Double-click on gate_cone.
The Component tab is activated.
As first placement reference (1) CSYS select the CSYS_RUNNER.
Set gate diameter DM to 1.8 mm.
Set H height value to 4 mm.
Click on Preview to display the gate in the graphics window.
Click OK to assembled the gate cone part.
Make sure all quilt surfaces are visible.

Create the Sprue Sketch

Create the Sprue Channels

Click EMX Components ▶ Library ▶ Assemble.
The Library Component dialog box opens.
Select runner folder from the library tree.
Double-click on trapezoid_es.
The Component tab is activated.
For W select a value 5 mm.
As first placement reference (1) Curve select a segment of the previously created sketch.

Click OK to assemble the sprue channel.

Note

The trapzeoid_es is not a part or assembly. It is defined as UDF.

Repeat the assembly of the trapezoid UDF for all segments of the sketched sprue curve.
Trim and merge the created quilt to finally retrieve the sprue.
Create round to avoid sharp corners.

Mirror the Quilt

Create the Sprue Puller Pin Channel

Click EMX Components ▶ Library ▶ Assemble.
The Library Component dialog box opens.
Select runner folder from the library tree.
Double-click on sprue_puller_channel.
The Component tab is activated.
As first placement reference (1) CSYS select the ORIGIN_MOLDBASE from the TUTOR_SKELETON.PRT model.
Click OK to assemble the sprue puller pin channel.
Merge the quilts.
Create rounds to avoid sharp corners.
Close TUTOR_RUNNER.ASM to return to the TUTOR_SHARED.ASM.

Design the Sprue Retainer Bush

Create a new part TUTOR_RETAIN_BUSH.PRT and assemble it to the ORIGIN_MOLDBASE.
Design the part using default functionality.

The major outline in this example is 38x38 mm.
Create to quilt surface which can be used for Solidify operation.
Create Soldify features in:
- MOLD_VOL_ES_1.PRT
- MOLD_VOL_ES_2.PRT

Create the Solidify Cuts for the Runner in Insert Parts

Assemble the Sprue Puller Pin

Click EMX Components ▶ Ejector Pin.
The Ejector Pin dialog box opens.
Select knarr from the Supplier pull-down list.
Select 37111 from the Types pull-down list.

1. For (1) Point select the point PULLER_PIN from the TUTOR_SKELETON.PRT model.
  The LG1 value is automatically set to 160 mm.
Activate Trim to quilt/refmodel option.
Select Rotfix1 from the Fix Rotation pull-down list.
Make sure to set the D1 value in the UDF Dimensions to 5.000 mm m the Fix Rotation pull-down list, otherwise the UDF can not be assembled.
Close the Ejector Pin dialog box with OK.
The pin is assembled and trimmed.

Cut outs are added to the TUTOR_RETAIN_BUSH.PRT.
Close the TUTOR_SHARED.ASM to return to the main assembly.
Click EMX Components ▶ Ejector Pin ▶ Add Ejector Bores from the overflow menu.
The missing bores for the puller pin are added to the mold base assembly.
