Autodesk Inventor

[#1]

Hello. Please check my project. I use szkic.ipt to control the shape of the container.

Please tell me why it all goes wrong when I change it and update? I loose references every single time.

If I suppress Klapa Gorna.ipt everything goes smooth.

Any idea?

Here is an idea - fully constrain the sketch so that you will know how it will behave.

This is usually covered in the 1st hour of Inventor training.
You might go through this document.

Which sketch? szkic.ipt  is not adaptive. Is it necessary to fully constrain sketches that are not adaptive?

[#4]

I did, but it doesn't help.

[#5]

Where is the Excel spreadsheet - you didn't include it in your attachment?

[#6]

You are right, here it is again

[#7]

I did not include the assembly.

Now it is 100% complete.

If I try to walk you through doing this correctly are you going to stick around to the end solution?
(I ask this question because I see so many things wrong and often when I start walking someone through a solution they want to take a bunch of short-cuts rather than make it right.)

You might start by reading this document http://home.pct.edu/~jmather/skillsusa%20university.pdf

1. You have posted your files here 3 times and the master sketch in Szkic.ipt is not constrained in all 3, even though that is the most basic of techniques in using a parametric modeling program.

2. I would not leave units undefined in a spreadsheet.

3. It looks to me like you are adding uneeded compexity feature tree (see attached image yours vs mine).

If you want me to walk you through how I would do the part, start by constraining your master sketch and then indicate you would like for me to continue.  Otherwise, I'm sure someone else will be happy to jump in here and offer shortcut solutions.  (actually if you look at my attachment I think my solution would be a real shortcut compared to yours, looks to me like you are doing wayyyy too much work)
