Auto Round™

Auto Round™ is a new feature that intelligently rounds edges of a part.  The Auto Round feature enables you to create round geometry of a constant radius on solid geometry or on a quilt of a part or assembly. The Auto Round Feature creates Round features called Auto Round Members (ARMs) and are represented on the Model Tree as subnodes of the Auto Round feature.

  1. Set Working Directory to CORE_DESIGN
  2. Open  autorounds_housing.prt.

  1. Select Insert > Auto Round.

 

  1. In the dashboard, Enter .05 for the convex edges and .1 for the concave edges.

 

From the Options panel in the dashboard, you can choose to have a group of regular rounds created.

 

If the design intent is not to round all of the edges currently in the model, the autorounds can be applied to selected edges only, by using the Scope panel in the dashboard.  As apparent in the message window shown above, it is also possible to select edges and intent chains to exclude.

  1. Select Complete Feature .

 

While Pro/ENGINEER is Auto Rounding the part, you can preview the rounds that are being created by selecting the "Show each member" check box in the Auto-Round player.

  1. View the rounds just created.

Hole Tool

Enhancements to the Hole Tool include:

  1. Set Working Directory to CORE_DESIGN.
  2. Open  hole.prt.

  1. Select the Hole Tool  from the feature toolbar.
  2. Pick a location near the center of the top surface of the part for the placement of the hole feature.
  3. Locate the hole on this surface by dragging the placement handles to the front and right surfaces.

  1. Set the diameter = 4, and the depth = 17.
  2. Change the Display Setting to Wireframe to view the hole preview.  Note the drill point.

  1. From the Dashboard, choose the Standard Drill Profile Tool .

  1. Using the dashboard try some of the other enhanced capabilities for this profile, including:

  1. Select the Shape tab in the dashboard and review the new information provided in this tool.

  1. Close the Shape tab.
  2. Select the Standard Hole Tool Create Standard Hole, then Tapered Hole Create Tapered Hole option.
  3. From the Thread Type flyout, review the enhancements to predefined thread types.
    NPT, NPTF, and ISO 7-1 have been added to the list.

  1. Select NPT as the thread type, and choose the Shape Tab to preview the options.

  1. Select Shading  display from the main toolbar.
  2. Select Complete Feature .

Shell Tool

The Shell feature has been enhanced to allow a surface with neighboring tangent surfaces to be removed, and or have a different thickness value than the default.  This improvement allows for greater flexibility when creating parts that need to be hollow.

  1. Set Working Directory to CORE_DESIGN
  2. Open  shell.prt.

  1. Select Shell Tool .
  2. Select the end surfaces shown below, as the surfaces to remove during the feature creation.

  1. Enter .5 as the overall thickness.
  2. Select Complete Feature  to Finish creating the shell feature in the model.
  3. Select the View Manager  on the top tool bar.
  4. Select the Xsec tab in the view manager, then RMB on the cross section named shell, and choose Visibility as shown below.

  1. Spin the model and take a look at the geometry that was removed during the shell.  Investigate the section in the model.
  2. With the shell feature selected, RMB > Edit Definition.
  3. Hold RMB and select the Non-Default Thickness option, then select the surfaces on the opposite end of the model as shown below, and change their thickness to .1

  1. Select Complete Feature  to Finish the edit definition.

 

The cross-section will not update until the feature is completed.

  1. Spin the model and take a look at the change just made to the wall thickness in the model.  Investigate the section in the model.

Remove Surface

The new Remove Surface Tool can be used in many ways, including:

  1. Set Working Directory to CORE_DESIGN
  2. Open  surface_remove.prt.

 

The geometry for this part was imported from a step file and is a single feature solid model that you will make modifications to.

  1. View >  , select Default Orientation.
  2. Change selection filter from Smart to Geometry.
  3. Select the (3) surfaces shown below using CTRL+Click.

  1. Select Edit > Remove to create the remove feature.

  1. Select Complete Feature  to Finish the feature and view the changes to the geometry.

  1. Try this tool on other geometry in the model.

 

This tool requires an Object > Action workflow.  All the powerful surface collections techniques are available, i.e., Seed & Boundaries.  Once inside the tool, use References > Details... from dashboard to assist with selection process.

3D PDF Export

Pro/ENGINEER creates the exported file based on PDF v1.6. Adobe Acrobat v7 and later support U3D graphics.
Universal 3D (U3D) is a 3D graphics format developed by Intel and the 3D Industry Forum (3DIF) for sharing 3D models and drawings on the Web and in common office applications. In order to reduce the file size for quick downloading and fast screen rendering, most of the engineering data associated with the original drawing is eliminated, also protecting IP.

  1. Open Open engine.zip; double-click on ac-40.asm.

  2. File > Save a Copy...

  3. Select U3D PDF (*.pdf) in the Type drop-down.
    By default, the current object name appears in the New Name field.

  4. Accept the default, or type a different name.

  5. Click OK. The PDF Export Settings dialog box opens.

  6. Click OK to complete the PDF export.
    Adobe Reader 8 will start automatically and load your file!

Optional Settings

  1. Click the General tab and preview the options available.

The Pro/ENGINEER model graphic is sized to fit on the selected page size, within the user-defined margins.

  1. Select the Security tab and preview the options available.

If you do not select Restrict Viewer Operations, anyone can print or copy from the document. To restrict high-resolution printing, change the option from the default, High Resolution, to Low Resolution. Certain options must be checked as pre-requisites to make sub-options available.

  1. Select the Description tab to specify descriptive information for the PDF document.

  2. Type relevant document information in the following boxes:
    Title, Author, Subject, and Keywords
