Renato,
Please disregard what I said and go with michael's advice.

Michael,
Seems more of an anomoly thing than a bug. and yes it has to do more with the fillet, then boolean, then fillet again. For instance here are three files. with the "boolean lines for MG_2.3dm" I generated the other 2. I also generated the same operation with 5 other attempts that worked fine.

One file lost a surface during the action. the other is the failure to fillet thing. After the failure I may have joined the 6 edges and deleted them then tried again.

Anyway, after doing it for 10 minutes, then paying closer attention to selecting things in some kind of fashion, it seems to do it ok. And if I do like you suggested and wait to do them all at the same time it seems to function correctly.

My previuous statements about the "Boolean" leaving lines does not seem to be accurate.

Thanks for the attention.

Hi Burr, well definitely the issue that you mentioned is something to look out for. It is easy to select a "curve" object instead of an "edge" object, especially since many construction techniques will put an edge of the resulting solid in the same spot as where your original generating curve was at.

It's probably one of the easiest areas to get tripped up on in MoI currently.

At some point I'm going to need to try and improve that situation... It's just a difficult thing to handle without popping up some kind of additional UI which I have tried to avoid as much as possible up to now.

I think your properties panel will handle that for me. Knowing what I'm looking at. Info on whats selected.

Thanks for your help!

Hi Michael,

I finally done it. Actually I had to come out with another way to make it, it was just a little change, but made the things work. I´ll use the printscreens to try to show the difference and after this little exercice I think I´m understanding better what Fillet can do or what are the conditions to do it.

In the first image [1.1] you can see I the things I used to make it.


1.1




In the second one [2.1] you can see the way I was doing that "border" before. I was using Boolean Diff with the sphere. In the third image [2.2] you can see what happened, I tried but I couldn´t use Fillet in that "border".


2.1


2.2




In the 3.1 you can see what I changed and then the results [3.2 and 3.3]. Well, the last one, as I can´t save and render it, I just used HIDE to hide the lines... hehehe...

Would changing MoI to make the two types of lines different colors be a solution?

Hi Ed,

> Would changing MoI to make the two types of lines
> different colors be a solution?

I'm not sure about that... It is tough to come up with colors that people will attach meaning to. If you see a bunch of different colors and you don't really have a meaning to attach to them, it doesn't really solve the fundamental problem very well.

Because of that, I've kind of tried in general to keep using colors down to a kind of minimal level that have more distinct meanings, like yellow = selected is pretty straightforward.

But I don't think it would be a bad idea to have an option to have them displayed in different colors if you want, I mean if you do know what those colors mean then that could indeed be helpful.

Also though, I want to support the ability to change colors on different objects as a way for you to separate them into different groups for your own kind of labeling purposes... That's another reason why I have kind of stayed away from using too many colors for the "system" because it then tends to get confused with your own coloring schemes.

One of the first steps that will help out with this is the properties panel that I want to do which will show up to show you some information about the selected objects. So I'll probably wait and see how that works first before really doing more in this particular area.

- Michael

I think the option to assign colors is a good idea.

Looking forward to a properties panel. I had a 2D shape that failed to obtain end caps during extrude. I was sure I had closed my curves with "blend" but one very, very small gap existed. I could have used a dialog to tell me the shape was not closed.

Ed

Renato,
Awesome with all booleans. Dont forget to check out the sweep and loft tools in MoI.

The same thing can be done by using loft with 4 circles.




I pick the bottom, then top down, then choose loft. Choose straight as a style. and chamfer your edges. (dont forget to erase the original circles)

Burr

BurrMan,

That´s a nice way to do it, I like when something can be done in a different way, there is a lot of different possibilities.

I used Loft in the first piece, using 2 circles. But I don´t know if doing only with Loft it would really be the same. The tip of the cone is like a little sphere, but it can be done after using the loft, so no big deal. But I used a sphere with Boolean Diff to make the concavity, if you use Loft for that wouldn´t it be a base of a cone? A cone upside down without its top?

Anyway, I liked the idea.
I´m trying to make more objects to learn more of each tool. As I said, I´ve no previous experience in 3D modeling so while I´m exploring MoI I´m also exploring 3D modeling... hehehe...
I just hope that when I give a try in Rhino, for exemple, it doesnt feel too strange or difficult... lol...

Next thing I´m going to try to make is a Wi-Fi USB adapter, my mouse, my cellphone... All the objects around me... hehehe... I hope that by the end of the month I´m able to make more complex things, the problem and the dilemma is: not be able to save or just have 30-day trial... cuz if I have to turn the computer off or Windows decide to stop working [like it does sometimes... bad temper... ] I´ll have to start it again... lol...

>But I used a sphere with Boolean Diff to make the concavity, if you use Loft for that wouldn´t it be a base of >a cone? A cone upside down without its top?

Yes Renato. I suppose I just dont pay close enough attention. Just passing on my excitement as I am learning MoI along with you. I hope you can save up and Buy MoI and then we can swap stuff as we chat. Good luck with the surrounding items!

Talk to you later,
Burr
