TAD 330- Making Isometric & Exploded Assembly View Drawings

The following will show you how to create the first two pages of the engineering design packet for TAD 330, which are the isometric & exploded views of a completed assembly.

• Completed .iam assembly file created in Autodesk Inventor (the 2019 version is used here)

• Open Inventor.
• Select File->New->Drawing
• Click ANSI (mm).idw

• Under the "Drawing Resources" tab,
  • Select "Sheet Formats"
    • Select "B Size, 2 view"

• After selecting B size, a prompt will appear to select the document you wish to include in the drawing.
  • Select the document.
  • Click "Open", then click "OK".

• Delete the view that Inventor automatically applies, since an isometric view of the assembly is needed.

• The view will need to be adjusted so that it is isometric.
  • Click the "Home" icon on the navigation cube to orient it correctly.
• The scale used in this example is 1/2
• The correct style for all isometric projections is shaded with no hidden lines visible.
• Click "OK" once all of the above steps have been completed.

• Center the isometric projection of the assembly to make it look presentable.
• Remember, this is the very first page of the design packet!

• Under the "Annotate" tab, click on "Text"
  • This will allow you to create a text box anywhere on the drawing.
• In the box above the "TITLE" block, make a text box and type "BEREA COLLEGE" in 9.53mm font.
• In the larger title box below, make a text box and put the name of the assembly in 7mm font.
  
  • In this example, it is the Leveling Assembly from Chapter 12.

• Under "Place Views", click "New Sheet".

• "File"-->"New"-->Presentation--> Standard (mm).ipn
• Click "Create".

• Once the assembly file has been selected, click "Open".

• To explode the assembly, click "Tweak Components".

• While holding down the "Ctrl" key, select the parts which you would like to move together.

• Ensure that both "Tweak Components" and the Lifting Block part are selected.
• Click on the direction arrow pointing upwards (Y-axis).
• In the dialog box, type in "180".
• The part will then move upwards by 180mm.
• Click the green check to confirm this movement.

• Ensure "Tweak Components" is selected.
• Use Ctrl + click to select both the Sliding Block and Adjusting Screw.
• Click on the direction arrow pointing upwards (Y-axis).
• In the dialog box, type in "120".
• The parts will then move upwards by 120mm.
• Click the green check to confirm this movement.

• Ensure "Tweak Components" is selected.
• Select the Adjusting Screw.
• Click on the direction arrow pointing to the right (Z-axis).
• In the dialog box, type in "100".
• The part will then move 100mm to the right.
• Click the green check to confirm this movement.

• Under "Presentation", click "New Snapshot View".
• This will take a snapshot of the tweaked assembly, so it can be used in a drawing.

• On Sheet 2 under "Place Views", click "Base"
• The exploded assembly should automatically pop up.
  • If it does not, search for the right file before continuing.

• Be sure to format and orient this exploded view in the same way as the non-exploded isometric view on page 1.
  • No hidden lines, shaded, and same scale (in this example, 1/2).
• Offset this view to the left side a bit as room will be needed to fit the parts list and balloons.
• Click "OK".

• Under "Annotate", select "Parts List".
• Select the exploded view as the document you wish to have a Parts List for.
• Click "OK".
• An outline of the Parts List box will appear; drag this to the top right corner of the drawing.

• To execute this, double-click on the Parts List.
• A dialog box will pop up.
• In this box, select "Column Chooser" (the leftmost button).
• In the "Selected Properties" column, click on "Description", then select "Remove".
• Under "Available Properties", click on "Material", then select "Add" to add it to the "Selected Properties" list.
• Click "OK".

• Get rid of unnecessary spaces in the parts list by dragging the columns left or right to minimize them.

• Balloons will allow the parts in the exploded assembly to be easily identified and compared against the parts list.

• To make sure all of the parts in the assembly have a balloon, ensure that when a part is selected, it turns blue.
• All the blue-outlined parts will have a balloon designated to them.

• After placing the balloons, click "OK".

• For maximum neatness, ensure that the balloons are somewhat aligned to each other, or that their lines are parallel.

• Instead of creating new text boxes for sheet 2 and typing the same information, the text boxes created in sheet 1 can be copied and pasted into the title block in sheet 2.
• When pasting the copied boxes into sheet 2, the outline of two boxes will appear in green.
• Align them within the title blocks and then left-click to paste.
• Press the "Esc" key once complete.

• The first two pages of the engineering design packet are now complete.
