problem loft

[ecomusposta]

Hello, guys, I have a little problem, I've been pressing that it's just been using inventor, but I think in my problem I don't think it's wrong, we come to the chase. I have to make an artifact with the loft command through the 2 cross sections that you can see in the annex, but when I go to select the second face, that is, the second curve does not make me select it, how come? thanks in advance for the answers given to me. waiting for a vs. I greet you. Where is it?

ah dimenicavo the version of inventor in question is professional 2009.

I know that maybe my problem is hard to understand. yesterday very quietly I threw out a little the book of the guide that I bought about a week ago on inventor, I also dared on youtube the tutorials, but in both I noticed something strange, correct me if I'm wrong; I noticed that in the examples I saw were all full cross sections, i.e. not masks. In my case it is a kind of mask, because I have the artifact that outside looks straight and inside is conical. How can I do that? I also thought of developing sections to one by one and then doing some kind of Boolean operation, a subtray, a separate, something like this exists on inventor?

In fact the inventor loft does not work with "frame" profiles, the road I recommend is:
First you do a loft of the outside, then share the sketch and make the loft "cutting the material" of the inside.

thanks stiky for the answer, but the question is how do I remove the material from the inside, is there a specific command? with autocad I was used to subtract and other Boolean operations, but here is the same?

the loft function allows both to add and remove material, mouse over the various icons of the loft window and you will see what it is to pajar to remove material.

Okay, thank you all, you were right. for correctness I say and place also the file of how I solved my problem. I created with the loft the whole part after which I always emptied with the loft the 2 smaller cross sections, giving me as a result the internal conicality. thanks to all, even if I would actually have another problem. I would like to give the loft 2 or 3 rails i.e. driving curves, but they touch in a tangent way the 2 sketches. I thought, if the sketch containing the guidelines built them by making a project geometry that touches the 2 sketches you think you can do? In the event that you have not understood my problem I answer, I thank you for the answer given me until now.

If you have the pruners guide, I think I remember that the passing loft for various sketches and/or points is explained very well taking as example the construction of a joystick, look at that example is definitely easier than explain it here. then if you have any further problems ask yourself. Bye!

ok, in the book there is written how to run the loft with guide curves, but I do not find the section where it speaks how to build a sketch with tangent lines to the other 2 sketches, using snap points to objects. I don't know if I explained.
I thought that at the time of building these guidelines I should create a sort of project geometry tangent to 2 sketches or 2 work planes, I don't even know if you can do it.

I have not understood what you mean, but if you build with a new sketch the path of your loft on a perpendicular plane to the two where the initial sketches lie, using "project geometry", projected on your new sketch the reference points you need (related to the two intial sketches) and with the imposition of geometric constraints you can give the trajectory the form you want. If I didn't play well, I think you'll have to post an example image of what you want to do. Bye.

I think I understand. But I wanted to ask you something, but when you're talking about "geographical vines", do you mean project geometry? to know if they require precise methods to bind guidelines to references. For example, I have bound the construction of an arch on the top of the sketch, but I don't know if I understood correctly, so I ask for confirmation. However I thank once again for the help.

by geometric constraints I mean those within the sketch environment (perpendicular, coincident, etc.), the "project geometry" sounds to me as much as it projects geometry, but aspect confirmed by those who use the software in English. In any case, in order to bind the lines drawn within the sketching environment, two ways are proceeded: with the quotas and the geometric constraints, combining them a completely bound and firm figure with the reference axes. Bye!

look you do not understand much from what you say, cmq to create curves guide you should use 3d sketch that allows you to draw lines, curves spline not by force belonging to a single floor (in space). in this way you can create rails that start from the top of the frame but follow traittorie that develop in space. design also of the lines that start from the vertices to use as reference for the tangence of the splines.
image place to make me understand better.
