sometimes I´m getting an error message which is telling
me that the operation did not change the number of faces.
As I am using extrusions to change the length in a certain
direction while leaving the basic length unchanged this is
quite necessary. The fact that makes me really curious is
that sometimes all Í need to do is to redo the extrusion to
make the message disappear... Sometimes I need to re-
Extruding a box farther won´t change faces, but is not wrong
and surely serves some purpose in my assemblies and parts.
How to avoid this?
Solved! Go to Solution.
of course I can, please have a look at the attached file.
Despite of the fact there is a error message sometimes
it all works very well.
It's probably just a matter of which option is being selected, or the default direction of the extrusion. You might also consider using the move face command, it you are simply extending the surface in the same direction. Just be aware that none of these operations will change the given length of the part, so part length in the BOM will not match any length shown on the drawing, without puting a sketch on the part to reflect the new length, or redoing the original extrusion. If this is acceptable then move face will work just as well. You could also set the extrusion as an adaptive part, which will allow it to adapt in length dynamically to any other constraints you place. So if you vary the height of your frame, the leg will adapt in response.
Attached something slapped together real quick to give you an example to see if such may be what you are looking for. Change the "Change Me" constraint to see how it works. if the rail height never changes, just the offset to the top of the leg, then change the other constraint set at 2" I believe I made it as. You would of course first have to ground the horizontal member if that is your intent.
Personally I would use Frame Generator, but thats another subject altogether
I see - it´s attached now.
Yes I know, and I almost added this line myself
I never took official training when it comes to parametric modeling.
The major problem was that I had to add correction values later on.
It started quite simple and more and more had to be added. I had
to turn fixed values into parameters and add geometry not included
in the first place. The 0,1 mm are to reverse coordinates. By now I´m
doing this by multiplying the value by (-1) but this started quite some
time ago. Conn a and Conn b are for FDS and connect parts to other
parts. It works pretty well despite of the mess. I did not create inde-
pendant bodies as they would be of no use so far. The UCS is for
Even if you might sound harsh you surely got a point - and that´s the
only thing that matters to me. When becoming a technical draftsman
noone ever eighter expected or demanded multi body object modeling.
I got to teach myself from scratch. Other parts look better, I´d blame
the changes that had to be made afterwards the original object was
finished. Beeing in a hurry I extended the existing model and did not do
If you consider sharing a e-mail adress, I might send you a model of
the other shelve I did. You´ll probably notice it´s way better. Just because
of the fact that all the variables have been laid out plainly before the mo-
ANY help is very welcome and I am a starter with not much experience
aside from school. And school did not cover this portion of Inventor or any
part of the FDS at all. I have been a good Student ( averaging 1,5, between
A and B it is I think and I could do all A easily) and a quick learner. But there
is not much material on the net of how to use model multi body objects in
the best way.
Go ahead, any lesson learned is a good lesson. I neighter mind nor am I
upset. So if you consider giving me a chance- I will not disappoint you.

I recommend you start here
Well, I posted that before taking a look at your file.
There are a lot of problems, but it looks like you are using some logic.
I recommend you use more equal (=) constraints rather than duplicating dimensions.
As you get experience - you might want to use the Frame Generator for a design like this.
If you get stuff in your feature tree like the UCS or the Connectors that you don't need, right click on them immediately and delete them.
