Yes but at the beginnig of a cession !
I suppose for an easy reading in the line bottom measure when you create different part of an object:)

I think it will first show up just as something you set under Options.

If you want to set it at the beginning of a session, then you would just go to options at the beginning of the session...

There are a lot of people who just want to model something and don't need to worry about what units they are working in. I kind of hate to force every single person to answer a question that they might not care about.

Eventually this will improve with the additional of start-up templates, but that won't be for V1.

Yes, in English CAD these are usually called "dimensions".

I do want to have them eventually but it won't be possible for V1 though.

Thx for all these explanations :)
Have you some plan about an "Help bottom line text" when a function is used?
On the empty place near the "Object Snap button?

I haven't really thought about that type of help... It might be a bit tricky because on a 1024x768 screen, there is no more space left next to the Object Snap button. My general plan for that area was to maybe try and have a customizable toolbar area where you could drop some of your frequently used tools so that they were always available at the top level (for a future version, not V1).

Some news complaints and info :)
System of group and hide something like that


And something seems ennuyous with the "grid"
An "infinite grid"on 2D views will be cool :)
When you change the numbers, scale change also :(
or maybe you have a"trick"?


Info about the process of creation of "Letter" in Moi after import "lines"
("back" are "fileted") is there loops inside?

Chamfer on a path = chamfer on a curve
Like a filet on a curve (2D)
Seems don't work with a chamfer? (missed something? )


Another thing when you choose "Chamfer" (in normal volumes use) and Input the 2 dimensions
Snapping grid seems disable ( I suppose for the dimension with decimal point but...:)

Ps A "circular" cursor resizable for select points when some numerous "show points" is enable :)
Useful for modify a complex volume! (a "drag circle"?

I see how the group works there, but I don't understand how the hide is different than MoI's hide, can he explain a little bit more about how the hide works differently there?

It looks like he just wants to make the grid extend out more - to do this, go to the Grid options, and change the "Grid sections" setting to something like 300 or 400. Don't make it too huge - if you make it something like 10,000 or more it might slow down the screen drawing.

This makes the grid extend out further, but keeps the scale of one grid square to be the same. If you change the "Grid size" setting, that will change the scale of one individual square of the grid.

Let me know if this doesn't make sense.


> Info about the process of creation of "Letter" in Moi after import "lines"
> ("back" are "fileted") is there loops inside?

Nope, no loops on this one. It looks like the font is different, the church text is narrower and taller than this. The bug probably only happens with some specific shapes, that's why it would be useful if he could send the original curves from that church model (if he has them around), it would probably be easier to reproduce the problem using those same curves.


> Chamfer on a path = chamfer on a curve

Ah I see, yes I forgot to enable chamfer for internal corners of a single curve when I added it for fillet. This was easy to turn on, it will be fixed for the next beta. In the meantime a workaround is to separate the rectangle into individual lines, then chamfer them two-by-two. Right now chamfer will work on curves, but only between 2 separate curves, not on a single joined one.

I can't seem to repeat this over here - for example, draw a box, select it and do chamfer. Now pick two points to define the first distance, grid snap is working ok for me here. Are you doing something different?

Thanks for all the reports and information, Pilou!

yes I pick my 2 points "directly" on the "up edges" of the box!
So snap grid seems disable :)
Sorry I am not an orthodox user :D

ps Seems cool trick for the "grid Section":)

Ah, I see.

But this is a feature, not a bug! :)

Object snap takes priority over grid snap, so if you have object snap enabled and you move over an edge, you should see a bit of text "On". This is showing that the "On" object snap has found an edge to snap on.

If you don't want to snap on the edge and instead only the grid, you'll have to turn object snap off temporarily with the toggle at the bottom of the screen.

It kind of has to work this way, because if grid snap had priority you would only ever snap to the grid since there are usually so many grid points visible on the screen.

So I kind of guessed what your next question might be - it would be nice if it was possible to find intersections between an edge and the grid, and have those points available. I think that is what you were really expecting?

This is unfortunately somewhat difficult to achieve with the general case of curvy shapes since there are so many grid lines. It is likely to cause a performance slowdown problem. That's why I have not attempted to do that.

Don't worry about that :)
It was just that appear "evident" (for me:) to draw the chamfer directly on the Box for pick dimensions :D
I very well understand that will be a task to code that with any slowdown :)
So again don't worry with that :)
Each user can find his own way, who is inevitably not the same way of the conceptor :)
I can pick my points elsewhere on the grid for entiere dimension :)

Ps
The separate edges'curve for "Chamfer" works like a charm!
Just "re join" after and that's make the trick :)

Pss Silly Question : After a Chamfer or a Filet of an object "Show Points" don't work!
Is that normal? (I am a little tired with this winter / summer hours changes:)
I must separate again for show it!

Difference "hide" between Hexagon MoI is that you can "unhide" object one by one !
Useful when you have a lot of object :)

A new video for show that when you select many objects, that became more slowly! Not with the camera moves but when there is a "multiple selection" !
Surely the "warm points" enable :)
No! Even all disable! ??? Some seconds for move a selection! ???

An undo / Redo for the selection :)
When you select 50 lines(object)...if one miss all is to redo :D

Another thing : here bottom windows are "reclosed" but drawings stay alive and imposible to erase it!
So a "cleaner tool" for old drawings :)
Video who show a boolean union with persistant lines!
http://stephlx.free.fr/MoI/bool.avi
But for me (Pilou, all works cool) see the image

But not in this one :(

But If I remake an another that works again!

Ps Have you some plan for a "reccording script" of all actions when objects are modelized?
For replay the creation as a pedagogic and funny way :)

With all this thrad time of developpment will be * 3 :)

Pss For a grammatical point does the word "complaint" is convenient for you or "request" seems better?

It's normal - it is a limitation of how NURBS work. You can only turn on points for an object with joined surfaces, if all the surfaces have the same control point structure along their common edges, and the common edges must be "natural edges" of the surface, not trimmed edges.

When you have a trimmed surface (which is the result after a chamfer or fillet operation), the control points of the underlying surface are different than the structure of the edge. This is what is really different between NURBS modeling and polygon modeling - in polygon modeling the edges you see are always the edges of the surfaces that are involved (they are one and the same). This is not always the case with NURBS modeling, here is an example:



Here the surface is a simple plane made up of 4 control points. The plane has a trim curve on it that trims away a portion of it. But the points that make up the trim curve don't define the surface, the surface is controlled just by the 4 surface points.

That's why in general you can't manipulate NURBS surfaces by dragging their edges as you would in a polygon modeling program - trimmed edges define regions of the surface but do not define the shape of the surface itself, if that makes any sense.

But on the other hand, this method of defining a surface is the reason why booleans with NURBS is so tremendously better than with polygons - every time you do a boolean or a trim, the surface stays exactly the same and just new trim curves are calculated. It's much more of a "nondestructive" type of operation. You can even recover the original surface by removing the trims later on if you wish. With polygon modelers, when you do a boolean it generates a tremendous number of new facets all over the place, the complexity of your object starts to increase dramatically.

So now imagine that I have another surface attached to the trim curve of that plane - for example an extrusion of the trim curve. This second surface has a totally different set of control points than the plane does. If I allowed you to turn on the points for such a joined set of surfaces, it would be really easy for you to grab one of the points and pull it such that it created a gap between what used to be a shared edge. This is why such point editing is not allowed, it is too easy for it to create gaps between shared edges.

Please let me know if any of this doesn't make sense.

This understanding of how trimmed surfaces work is really a key idea in understanding why NURBS modeling does not follow the same type of face/edge/point dragging as poly modelers. It's a very different structure and they have very different ways of working. Each way has its own particular strengths and weaknesses.

I saw it just briefly, I haven't had a chance to go through the steps myself yet. (By the way these videos are really cool, it's definitely easier to see them in Flash than using that special codec).

One thing I noticed - there is a portion where he moves some of the control points around.

One thing you kind of have to be careful of is to not move control points such that two points of a single smooth curve segment become stacked up exactly on top of each other. This sort of degrades the smoothness of the curve and it will probably cause problems for more advanced operations such as surface/surface intersection later on.


> Difference "hide" between Hexagon MoI is that you can "unhide" object one by one !

I see. So when you go to unhide, it temporarily shows the hidden objects, lets you pick some of them and then only shows those particular ones, is that correct?

This would have a side effect of making unhide take an extra step. I'm a little worried that it might make it confusing for people who are just hiding a couple of objects. But I can see that it would make it much more powerful. I'll give it a try and see what it feels like after the mesh stuff is completed.

Ah I see - this is when doing a transformation, such as dragging.

Yeah, this area is quite a bit different than just the regular display such as when moving the camera, it will be possible to optimize this part quite a bit more in the future.

If he can post the model he was showing somewhere, it would be useful for me to use when I get a chance to work on this.
