Scaling

[Anonymous]

How do I scale parts and assemblies in Inventor.  I"d like to be able to change the size of parts, sub-assemblies and full assemblies up and down by a uniform amount.  Ideally, I'd be able to increase or decrease the size of a part or assembly in all three axis or only in one at a time.  Any information would be a great help.  Thanks.

Derive component is one way to do x y and z.

iLogic is another way.

Hello J.D.,

Thank you for such a quick response.  I have to admit, I'm a little lost.  Can you be a little more specific?  Is Derived Component as drawing process with several steps or is it a single command/function?  I looked on YouTube and all the posts are without any sound!  Any help you can share will be a great help in reducing turn time on parts that are no longer the correct size.  Thank you again.

Best wishes,

DeeZein

What version of Inventor are you using?

2010?

2011?
2012?

other?

Hello,

I'm using Inventor 2012.

Scaling parts and parts that are not correct size are really two different issues.

Can you attach an example part and explain how it is wrong?

Hello J.D.

Sorry for the confusion.  I attached the assembly. If I wanted it to be twice as large or one-quarter the size how would I do it?  Thanks.

Look at the size of that file (47k).

An iam file is nothing more than a list of hyperlinks to the part files and a record of assembly constraints.

In other words, and iam file without ipt files is useless.

Put the ipt files in a folder.
Right click on the folder and select Send to Compressed (zipped) Folder.

Attach the resulting *.zip file here.

Sorry.  I usually send JPEGs.

As I suspected - you have a bit to learn yet in using Inventor.
I recommend you start here http://home.pct.edu/~jmather/skillsusa%20university.pdf

I noticed that you sketches are not constrained and you did not make use of symmetry about the origin even though your parts have a lot of symmetry.  In short, you are working tooooo hard.

I would have used multi-body solids technique that would make the entire process much easier.

But since you didn't -

Start a new part file.

Exit Sketch

Click Derived Component and select one of the parts to scale.
Set the desired scale factor and continue on.

Continue to ask questions as you run into problems.

To do non-proportional scaling takes a bit more using a special tool.

I think you might be better off concentrating on improving modeling skills by doing over rather than taking a short-cut at this point.

Someone else might be willing to show you the non-proportional scaling method.

There a funtion/tool for non-proprtional scaling provided by autodesk. It's by default hidden for every user.
Go to de sdk folder ( its stored in c:\programfiles\autodesk\inventor 2012\sdk) and install de usertools.
Than choose derivedpart_sp to install
