Return to Assembly

This is a video. When demonstrator return to assembly orange part is moving downwards. In my one orange part is remaining at the same position. Why?

Time around 10:00

The first thing your instructor should have covered is that an assembly without parts is useless.

Q1. What filename extension does Inventor use for part files?

Q2. What filename extension does Inventor use for assembly files?

Your instructor should have explained that it usual practice to Ground the first part in an assembly and why this is important. (Remember using the Origin Center point in part sketches - and why that is important?)

Instructor has not come to assembly yet. I have explore many videos in YouTube about assembly without parts.

If you want I can give you that link as well.

Even if I grounded the basic part it didn’t produce the desired result.

-------------------------------------------------------------------------------------------------

1st part (Grey colour) was modeled in a part file and imported to assembly file. 2nd part (orange colour) was modeled in the assembly file as demonstrator did.

All the files are on desktop for convenient to use it.

1. That is not a correct statement.
2. You did not answer questions 3,4 & 5 (which would lead you to why I made statement #1).

OK, let's make this a timed quiz. Time is up.

The correct answers below.

A3. Only I have access to my Inventor data files (unless someone hacks my desktop).

A4. Then entire world has access to the files I attach here.

A5. Only I have access to my parts named Blue.ipt and named puzzle cube.ipt on my desktop.

But now I have posted the parts named puzzle cube.ipt and Grey.ipt on the Autodesk forum - so the entire world now has access to those files. I have not posted the file named Blue.ipt, so only I have access to that file (unless someone hacks my desktop).

Hint: See how easy this is when the questions are answered (correctly).

What is meant by IAM file?

Post # 4 & 5 should answer that question.

I am unable to understand your approach to the issue. Therefore I am unable to proceed.

I am thinking how to simplify this issue so that I can get a solution in a one-shot.

In Post #4 you are asked 2 Questions:

Q1. What filename extension does Inventor use for part files?
Q2. What filename extension does Inventor use for assembly files?

In Post #5 you are given the 2 Answers. Let me rephrase the answers in a more clear way.

A1. An Inventor part file has the extension .ipt

A2. An Inventor assembly file has the extension .IAM

So, the meaning of a IAM file is that it is, an Inventor AsseMbly file.

In this thread, we learned a preferred order of projecting geometry.

Here is a repeat of the list from that thread.

1. Project only the Origin and use that for all reference.

2. Project endpoints of sketch lines as needed.

3. Project sketch lines or circles as needed.

4. Project part edges.

5. Project part faces (loops) or cut edges.

6. Cross-part projection in assembly.

It was stated that beginners should be using only 1,2 or 3 and if they felt compelled to use 4,5 or 6 they should first come here and ask questions.

In you part created in the assembly you used #6, the least preferred technique (for a beginner) of projecting geometry.

I watched the video link you gave above, and at no point did I see the presenter suggest that you should use Cross-part projection in an assembly (Adaptivity).

Write out the list of 1-6 above on a sticky note and place it on the screen over top of

then anytime you go to use the tool - first review the list and then you can flip the note up or come here and ask question about the correct Projection to use.

By the way - you still haven't attached the part Blue.ipt that is referenced in the assembly file (*.IAM or *.iam) that you attached here.

--------------------------------------

Problem was I couldn’t follow you therefore, I deleted relevant files in my system (Because to reduce garbage in my Desktop). And decide to return to this video after exploring more relevant videos in YouTube.

If I can rememember I attached all the files . I changed the colour (Blue was changed into Grey) only for my convenient.

Even in the Recycle Bin I couldn't see any Blue.ipt file only Grey.ipt I can see.

They were easy parts - start over from scratch.

Are you using Projects (*.ipt) files?

Do you have an Oldversions folder?

-----------------------------------------------------------------------------------

I will start from scratch as you advised. As a beginner my files are very small therefore I didn’t bother to use project files. There were large no of files in the Oldversions folder I deleted that as well.

Use of Projects (*.ipj) has nothing to do with file sizes. This is all about file management.

I recommend that you create a Folder with a name something like ClassName Projects and then create a ClassName.ipj file within that folder and make the project active.

The number one issue I have with any CAD user is one who has not learned robust file management techniques.

It doesn't matter how good you are if you can't keep track of your work.

I simply will not accept any excuse for loss of a file for any reason from my students.

Create a Project and Save Often (I tell them that so often that they printed t-shirts with my directive in one of their other classes).

I have been known to hit the room circuit breaker an hour and a half into final exam. (they are warned of this 1st day of class)

I got this idea from a squirrel who got into a transformer on exam day about 20 yrs ago.

The students thought it was the end of the world when they lost their exam work.

It was the end of the world for the squirrel....

In fact I was not aware that I was using “Cross-part projection in assembly”. Could you please explain that?

.......Cross-part projection in an assembly (Adaptivity).

------------------------------------------------------------------------------------------------------------------

From the wording I can undestand that Cross-part projection means importing a part from the part file to assembly file and using that part as a reference to model another part.
