Autodesk AutoCAD Questions & Answers

You can use Inventor’s Attribute or AttributeSet functionalities to save any personal data in an Inventor file like AutoCAD’s Xdata or Ldata.

Inventor allows you to import 2D AutoCAD geometry into a sketch within an .idw file. This can be done manually or automated via VBA/iLogic.

Manual Steps (for reference)

1. Open your .idw file.
2. Start a new drawing sketch.
3. Use Insert → ACAD from the ribbon.
4. Select the .dwg file.
5. Choose layers and objects to import.

This converts AutoCAD geometry into Inventor sketch entities.

Example VBA Snippet (Conceptual)

Sub InsertDWGIntoSketch()
    Dim oDoc As DrawingDocument
    Set oDoc = ThisApplication.ActiveDocument

    Dim oSheet As Sheet
    Set oSheet = oDoc.ActiveSheet

    ' Start a new sketch
    Dim oSketch As DrawingSketch
    Set oSketch = oSheet.Sketches.Add

    ' Simulate command to insert DWG
    ThisApplication.CommandManager.ControlDefinitions.Item("DrawingInsertDWGCmd").Execute
End Sub

These tools typically work by:

1. Exporting Inventor geometry to a neutral format like STEP or STL.
2. Converting that geometry into MCNP-compatible input using a translator or mesh-to-cell converter.
3. Generating MCNP input cards (cells, surfaces, materials) from the converted geometry.

Some known tools or workflows include:

• SuperMC (from FDS Team, China): A powerful GUI-based tool that supports CAD-to-MCNP conversion.
• MCAM (CAD/Image-based Automatic Modeling Program): Often used in nuclear engineering to convert CAD models into MCNP input.
• Simple custom scripts: Some users write their own Python or MATLAB scripts to parse STL files and generate MCNP geometry.

Yes, you can use ClientView to view Inventor documents -but not directly for AutoCAD .dwg files.

You might find some useful plugins on the Autodesk App Store—it has a variety of add-ons for Inventor and AutoCAD that could help with scaling inside the Sketch environment.

To add line weight in Auto CAD, follow the steps given below:

• Go the Home section and open the Property panel
• Choose Lineweight
• Open the Lineweight setting and then alter its properties as per your requirement.

To print actual size using AutoCAD, follow the steps given below:

• Open your model in AutoCAD
• Set the scale to 1:1
• Open the Print page by pressing Ctrl + P
• Choose your printer from the device type
• Again, choose the aspect ratio to 1:1
• Select window and choose your model
• Now just press the Print model.

To determine the scale of a drawing in AutoCAD, follow the steps given below:

• Tap on View from the menu bar
• Select the Viewports panel > Scale Monitor
• The drawing's scale can be viewed in the Scale Monitor dialog box.

To find the vanishing points in AutoCAD, follow the steps given below:

• Import your perspective artwork onto the AutoCAD
• Make a horizontal line
• Extract a line that is in the same direction as the horizon
• Now just find the point of intersection. That is your vanishing point.
