Re: Open Inventor 2013 .ipt in Inventor 2012

You're only as good as your teacher/ book, and school. My teachers of Solidworks and Inventor (different instructors) both teach part-time, they have full-time jobs off campus. When you went to school how long of a course was it in duration? Inventor will be 2-10 week sessions of 4 hours a week, Soldiworks will be 4-10 week sessions of 4 hours a week. When I ask what is wrong with my drawing, I'm asking for concrete examples, kind of like you asked of me about Inventor. If you're gonna criticize the lines in the drawings that is because the Inventor drawings fall apart when you try to remove them. I tried removing them on 5 different drawings and I ended up redrawing all of them so I gave up on them, and no they aren't frowned upon in class. You need to take CAD classes in college, because employers expect you to graduate with a degree before they will hire you. This way they can safe guard it with a college. This is why I am working toward a second degree. You give me some constructive criticism, then I'll see if If I'm interested in your help. Your help couldn't hurt, but right now without constructive criticism, your story isn't credible. I got some already, but that wasn't you, and I already explained that much.

It should not take an experienced instructor more than a couple of minutes to determine the problem. (in Inventor or SolidWorks)

 

I missed the current comment of this nature, I know it's hard for you to understand Inventor having a hiccup when I and my teacher spent 90 minutes on it, or the episode Thursday night, you're just gonna have to take my word for it. AutoCAD is notorious for hiccups, and Inventor and AutoCAD are made by the same company. Twenty-One times and it would not extrude, yet on a different computer (at home) it worked just fine. If it was a problem with the student, it would only take a couple minutes to determine the issue, but it was the computer with the software that was loaded was the issue. I look forward to your constructive criticism.

I'm not nearly as experienced as JD, especially not at teaching people to use Inventor, but I agree that the instruction you have received to this point is inadequate, to put it politely.  Please read through the document that JD referenced (in message 22). 

 

In addition, many of us would like to take a crack at the problems which you claim show Inventor in a bad light-- many thousands of people are using Inventor every day to create very complex models and assemblies, invent cool new things, and generally make their living.  Inventor isn't the perfect solution for every design task, but it is very usable.

 

The attachment is my first shot at modeling the file you attached.  I started out with the first sketch constrained symmetrically about the center, which simplified most of the succeeding features.  Each sketch from there on is fully constrained/dimensioned.  I observed that many of your sketches had no dimensions or constraints at all-- how can you design something like that?  To make any changes to the design would be incredibly difficult.

 

I also added a little clearance to your 12mm holes and slots, since in the real world you will have difficulty forcing a 12mm fastener through a slightly undersize 12mm hole, or finding an 11.8mm screw.

 

I will be away from the office and from Inventor the rest of the week, so if you have questions about my modeling technique, you may have to depend on others for answers.  I hope that JD has time to coach you through some modeling tasks.  Most of us here have learned more from him than from books or classes.  You might search through the forum for other cases where he has tutored a new user in various techniques.

Can you post an example of an AutoCAD "hiccup" you have experienced?

Yes I am well aware of the hole tolerances, I was a mechanical drafter of 4 years before being laid off cause I had no Solidworks experience. There are dimensions on the drawings, just no location addresses like D1, I haven't learned yet how to turn of the dimensions, well I did, but I don't remember. There are none in the 3D realm cause we haven't hit that part of the book yet assuming that it is in the book. I'm quite shocked though, that we're on Chapter 9 of 18 chapters and there has been no reference to actually being able to create a drawing that could be printed and used in the real world, it makes Inventor look like a presentation tool of little value, a $5000.00 presentaion tool that can't be printed out into a usable drawing, and this is a direct reflection of Sham Tickoo the author, cause that is the way he laid out the book. What you did is basically what I did. I tried deleting all those extra lines a few times, and every time I did it, it corrupted my drawing, I never did ask the teacher about it, but he has seen all my work, and this is the same kind of work the other student exhibit. I used the extrude cut to create the holes cause it works better for me, the hole command is still a learning curve.Thank You Sam B for taking the time to draw that up, I have always thought the extra lines looked horrible, I just could never delete the lines without the drawing parts being deleted. Sam how many hours of class time did you receive to adequately learn the software? Our program is a total of 80 hours, where as Solidworks is 160 hours. I'm guessing you all had a couple years of training or actually had good teachers.

Almost everything I know about Inventor - I learned right here on this forum.

Tolerances? Nobody said anything about tolerances. What was mentioned was clearances. But then again, since you clearly know everything about everything...

 

It's not AutoDesk's fault your teachers aren't teaching you correctly.

 

I spent a total of 8 years in school learning drafting and CAD and I've worked in the Industry about 4 years. I still have a ton to learn, and I spend my time on this board trying to learn all I can from the very experienced and knowledgable users on this board.

 

You need to close your mouth and open your mind, and you might learn something useful.

I use Inventor and SolidWorks both on a regular basis.  Both are very strong programs and work very well.  Granted, each program has it's bugs, but I don't think this is your problem.  From all the issues you have been posting about, I would say your main issue is improper training.  There are many options out there as far as training goes, maybe look into something else.

I haven't used AutoCAD since I was last working which was very early 2010, it would hiccup about once or twice a week, or once or twice every two weeks. It wasn't any certain instance that I remember, it was just anytime it wanted, but before you start comparing my Inventor to AutoCAD, I am quite proficient with AutoCAD or at least up to the 2010 version. I just can't remember any examples off hand of the hiccups, except of extruding along a path that had multiple curves at many angles, and it would not extrude at one time, I had to extrude pieces and union them together, that particular instance I would say is more of how the software was written, rather than a hiccup, cause it's more of a 2D software, although I've done a lot of 3D work with it. I still have the drawing that I extruded in several attempts. JD how many hours of class did you go through in school on Inventor and Solidworks?

 

Thanks

I mean the foundation that started your learning of SW and Inv, how long was it?
