Good evening to all,
Meanwhile, as I am new to the forum, I greet all and thank you because in the past, even if I was not yet enrolled, I found various solutions to problems I had.
I have now a problem in inventor, especially in the metal sheet environment. what I would like to achieve is a bombing of a sheet, as it is often done to spray metal doors or surfaces constructed with fine sheet metal and large enough. in practice it would be to build a square face (say 100 x 100) and then fold it (with low angle, say 2°) on both diagonals, so as to have a very small pyramid.
I have seen this process use it several times in various workshops for the realization of doors panels, so it is very feasible, but unfortunately, despite having made several attempts, I can not do this with inventor.
Can anyone help me?
I hope I was clear, otherwise I will try to explain myself better... .
thanks to all

the classic "diamantling".you could try with the loft.mi remember that from one point to a surface makes it so you should see how far you draw the contour from the point to have the inclination of 2 degrees.

Davide,
First of all thank you 1000 for the answer and indeed, trying, I managed to get something similar to what I wanted with the method you suggested (I say something similar because at this moment I did not make calculations to get the desired angle), but I can not (surely for my inexperience) use a single point as a termination. I explain myself: I create the first sketch in which I design the square 100x100 (and so far no problem), then I generate the parallel plan to that of this sketch with 5mm offset (just to try - no problem even here) and above I should draw a point and then make the loft of the 2 features, but unfortunately I can make the loft only if instead of the single point design a circle or a rectangle also very small.
Do you have any idea what I'm doing wrong?

if I can give a suggestion I feel to say that it is not necessary to draw in 3d the diamantatura, the development does not change, indeed your model is not developable. Surely it is enough that the signs in the table with a note, and what most designers forget is the verse in which the diamond should be made.

 

[Wolf81]

Marco, thank you for the answer,
In fact, what you say is true....the model is not developable (not that there is need) and so it is worth representing it only.
Anyway tomorrow I try to see if I can get a model with the loft (as suggested by davide) that I would be more useful to use it for assembly, otherwise I will follow your advice.

 

[davide75]

Sorry but I did it now with 2009 and use the projection of origin as a top of my diamntatura.When you open the loft menu in the section pane select the first sketch and then click to add another one and then go to clear the point.try.

Davide,
I begin by saying that I solved by making a very small square instead of the point and, at least for my purposes, the solution is fine.
I still tried to do what you say (or at least what I think you say :d) but with my version (2010) I can't. In particular I cannot select neither the origin nor a point as a profile for one side of the loft. If instead of the point I make a small square, circle or rectangle, instead it's okay.
I'm probably the one who didn't understand well, but anyway I can consider solved my initial problem.

thank you very much to you and to marco for the answers.

 

[davide75]

but do you project the origin?? ? I do it with the 2010.I see to post you the figure.

 

[davide75]

here is an example file made with 2010. see if you can go

 

[Wolf81]

I looked at your file and tried to replicate it. In fact it works exactly as you say, but the problem that I couldn't do was that I felt inside the sheet metal environment instead of normal modeling.
in the normal modeling inventor allows you to select the point of origin (or its projection) as a loft top, while in sheet metal no (and I used this environment because thinking of making a folded sheet seemed more suitable).

Anyway I also solved with sheet metal making a small square instead of the point.
Thank you very much for your concern and suggestions.

cmq to the maximum you make the solid full and the empti.scusa I had escaped you were in the sheetmetal environment but cmq you can pass from sheetmetal to solid modeling quietly since there is also the solid modeling bar inside sheetmetal.
