Inventor Tips

Gaining Perpective in Inventor
 
This is a neat trick for Inventor users who want to create a wowser presentation.
 
If you have designed some equipment that goes into a room, get a photograph of the room.
 
Set the background of Inventor to the jpeg photo.  (Go to Application Options, Colors, then browse to select the image.
 
Position the model in the room.
 
Set your model to Perspective view (this is on the drop-down on the View toolbar) and then zoom in and out until it is scaled properly with the room.
 
Now, hold down the Control and Shift together and scroll the mouse wheel up and down.  You will be able to adjust the perspective until your model looks like it really is in the room.
 
Awesome!

Trigonometric Functions in ParameterS (*.ipt)

> Use the same formula for the parameter as you normally would with a slight modification. The formula must evaluate to linear units. To make the parameter evaluate to linear units, multiply the formula by 1. If you do not do this, the formula will evaluate to a unitless value (or a dimensionless value). Because Autodesk Inventor interprets "1" as 1 inch, the result of the formula will evaluate to an inch value.

D2 = sin(D1)

This will evaluate to a unitless value. Using the workaround, the formula will be:

D2 = sin(D1) * 1

This will evaluate to linear units in inches.


Adding Different Text or Terminator Sizes to the Defaults (*.idw)

Follow these steps to add additional text heights to an Inventor Drawing.
(You have to be in an idw file.)

  1. Go to Format->Standards.
  2. Select the Common Tab. In the Text height area, enter in the text height desired. Press 'Apply' and 'OK'.
  3. Go to Format->Dimension Styles.
  4. The new text height can now be selected in the Text tab.


Redefine Isometric View (*.ipt/*.iam)

To change the default isometric view, initiate a Common View Rotate.

Position the part/assembly as desired.

Right click and select Redefine Isometric.


Delete Versions From a Drawing File

> I reset the number of versions that I want to keep to 1 but the drawing still list 2 versions available.

Try "Compact"-ing the .idw through windows explorer (right click on the file)Then re-open the .idw and do a couple of saves and see what happens.

Make sure the .idw is shut down first-you can't compact an open file.


Linking Parameters to a Parts List (*.ipt/*.iam)

> If you check the box next to a part. You can then add these custom fields to your Parts List.

  1. Create your views in your drawing for the assembly.
  2. Add the parts list.
  3. Edit the parts list.
  4. Select Column Chooser.
  5. elect Custom Properties.
  6. Press the New Field button.
  7. Type the parameter name you wish to include in your parts list.
  8. Add the Custom Properties to the Selected Properties window.
  9. Press 'OK'.
  10. The custom property appears in your parts list.
  11. Press 'OK'.
  12. Go back to the part.
  13. Change the value of the parameter.
  14. Save the part.
  15. Go back to the drawing file.
  16. Edit the Parts List.
  17. Press the Compare button.
  18. The parameter that changed will highlight in yellow.
  19. Right click in the cell and you will see a menu.
  20. Select 'Update Value'.
  21. Press 'OK'.
  22. The Parts List will update.


Stacking Balloons in an Assembly Drawing (*.idw)

To stack balloons, place one balloon, exit the balloon command.

Right mouse click on the balloon and select "Attach Balloon". Select the part to be used for the next balloon. Repeat for as many balloons you want to attach.



Rip Corners in Sheet Metal Parts (*.ipt)

> To add rips to a corner, use the Corner Seam tool and enable Corner Rip.



Constraining a Sketch to the Origin

Use 'Project Geometry' to copy the center point into the current sketch.



Changing Dimension Height in Sketch

This feature is available in Inventor R6 and above.

Go to Applications Options.

Select the General tab.

Set the Annotation Size.

You can also set the font to be used in your sketches here.



Adding Fastener Material to a Parts List

You've used some Inventor fasteners from the Standard Parts library and you want the material to appear in the parts list...here's how:

To have the correct material shown in the parts list.

On the Assembly menu, click Place Content.
Select the part and size required and click CAD.
Save the part as a SAT file.
In Autodesk Inventor, select Place Component and select the part you have just saved. Insert it into your assembly.
Open the part and on the File menu, click Properties.
Click the Physical tab and select the material.
Save the part and start a new drawing file.
Create a view of the part and create a Parts List with a Material column.
Instead of listing "Default" for the material, the material you selected is listed.



Calculating Moment of Inertia for an Assembly/Part

Inventor only provides Mass Moment of Inertia about a part's centroid. If

you want to calculate that part's MI about another point you can use the

Parallel Axis Theorem:

 
I(x,y,z) = I(xc,yc,zc) + md^2

I(x,y,z) = the axis you are trying to solve for MI about

I(xc, yc,zc) = the parallel axis through the centroid which IV gives you

m = the mass of the object

d = normal distance between the centroid and the I(x,y,z)

 

Another method is to mirror the existing assembly about the axis you

want the moment of inertia about and then dividing the MOI in two for that axis.

 

Accessing the Inventor Library in Inventor R7

To access the Fastener Library in Inventor R7, open an assembly file.  Select the drop-down arrow next to Model and select Library.


Changing the Center of Rotation in 3D Orbit

To change the rotation center, place your cursor over the intended rotation point and left-click your mouse.  Inventor should bring that point to the center of the "cross-hairs" and will use that as the center of rotation. 


Dimensioning to an Apparent Intersection

To dimension to an imaginary intersection point - Use the dimension tool and pick on the first edge of your part then right click and pick intersection then pick the second edge. It will take a little getting the hang of it but it will work.


Analyze Faces in R8

The Analyze Faces tool was added in R6. In R8, it's still there, but it's hidden. In order to access the tool, you need to add the command to one of your active toolbars. You will not be able to access the tool from the Tools menu or the toolbar until you add the command to your toolbar. The Standard toolbar is the best choice if you plan to use this tool on a regular basis.

The tool is used to analyze a face or a part to check surface continuity. The tool applies parallel lines so you can easily identify tangent points and inadequate "pull" for face drafts.


Moving Titleblocks from One Inventor Version to Another

The question from the user was this: I have Inventor R8 and Inventor R7. I have created some custom titleblocks in Inventor R8 and I want to update some of my R7 files without having to bring them into R8 with the new titleblock. Can it be done? The answer is 'yes, you can do it,but it is not painless. Here are the steps:

  1. Save your idw file with the new titleblock as a dwg file - save as a layout, make sure you note the units used.
  2. Close Inventor R8.
  3. Launch Inventor R7.
  4. Select Open and set the file type to dwg.
  5. Locate the file you created.
  6. Select Next
  7. Set the Units (or you will have a titleblock out of scale to your idw sheet)
  8. Select Next
  9. Select TitleBlock as the Destination
  10. Select Finish.
  11. A new drawing will open.
  12. Look in Drawing Resources\Titleblocks. You will see your new titleblock listed.
  13. Highlight the titleblock under Drawing Resources. Right click and select Edit.
  14. You will see that all the lines, geometry and text has been retained, but none of your labels. You will have to redefine the labels.
  15. Once you have redefined the labels, right click and select Save Titleblock.
  16. In the next dialog, select Save As..
  17. Rename your titleblock, so you don't have a path and you have a real Inventor titleblock for this version.
  18. Now, open the idw file where you want to place your new titlelblock.
  19. Go back to your previous file with your newly defined titleblock.
  20. Highlight the new titleblock. Right click and select Copy.
  21. Window back to the file you want to update.
  22. In the Drawing Resources\Titleblock folder, right click and select Paste.
  23. Delete the titleblock in the sheet.
  24. Insert the new titleblock. You may have to edit some of the fields.
  25. Save the file.

 


Controlling Line Visibility in Drawing Views

A great method is to just select the unwanted line, right click and uncheck Visibility. This gives you even more control than turning off the visibility using Show Contents in the Browser.

 


Straightening a Section Line in a Drawing View

You create a section view by drawing a line through a view...even with the dot...dot help, how many of us struggle with creating a straight line?

So, you make a line that's allllmost straight, but still not perfect. Select the section line. Right click and select Edit.

Now you are in sketch mode. Simply apply a horizontal or vertical constraint to your section line and you are good to go!


Visibility of Work Points in Wire Segments

To turn off the visibility of the work points in wire segments using Inventor Pro, go to View > Object Visibility > uncheck User Workpoints or +.
