Tank for all ;-)

Thanks Michael, giving it a whirl right now.

Cheers

Thank you, Michael. 'SKP format export' works like a charm.

Hi Michael,

Had a preliminary run for about an hour and just some comments on some of the new stuff.

The Free Rotation option with a spaceball is like, getting rid of my crutches and I'm finally walking normal again, thanks for that Doc :)

Naked edges, fantastic! works great !

Circle and arc tangent command update, where has that been!? ;)

CPlane IMHO is one of the major updates in modelling tools added, it will make modelling life so much easier again, I thought MoI couldn't get any easier and the placement intelligence behind it makes it so quick.

One thing with CPlane Michael, is that when using construction line/helpers to set the new plane the helper lines tend to hang around for a while, then they disappear after a few more commands, was this intended ?

Apart from that, all is good so far :)

Cheers

Hi Michael,

Really nice this new beta, love the Cplane function!

However I have problems with the SketchUp exporter.
I get a message that there is something wrong with the geometry when I open the file (I use SketchUp Pro version 6.4.112).
I`ve attached the 3dm file.
It is just a box and a 3pt curve that have been extruded and shelled, and later filleted.

Is it a user fault or is it a bug?
I used the default meshing option, and tried both weld edges and not.

Eric

Oh thank you Michael,

will try that tonight

Cold

no problem for me except these 2 faces missing! (up & down)

Hi Michael
tanks for these improvements
I hope that you remenber -Isocurve- for the next beta .....
al

thanks, Michael

..................and "group and ungroup objects" !!!!

Thanks Michael ...

I sure know how I am going to spend my evening, too.

Great program with great future promise.

Hi French Pilou,

Did you get the a warning that there is a problem with the model?

I get the same holes as your attachement just more of them.

See attached jpg.

No message for me ;)
Google Sketchup free 6.4.112

new try
Now I have made that
Erase the Up and down facetts rounded
then select for up and down the outlined internal then Planar = only one "facet" for each up & down
Export SKP
Result :in Sketchup all is fine except the Uper face is inversed so inverse it and all is fine

Are you sure of the construction of your Cylinder?

Hi Danny, thanks for the feedback!

I thought that would be more comfortable for you! :)

Great, I'm glad that the placement mechanism is working well for you.

Yeah when you place its origin point it will try to automatically align itself to the object you snapped on to. Hopefully for most situations that will be the orientation you were looking for already and you can be done right there.

But after the initial placement you can also click and drag on the axis lines to get a kind of "align to 3 points manually" type of style as well. After you have placed one axis, it will behave a bit differently for the 2nd axis drag - the first axis that you dragged will stay locked in place and the next pick will rotate about that first locked axis. This can be a bit strange if you are just trying to play around with dragging axes around because every other drag behaves a bit differently, but it should make sense I think if you are focused on placing them by 2 picks after placing the origin.


Then the idea is that this same placement mechanism will also be used for a Transform/Orient tool for aligning objects to one another - that one will use 2 of those tripod pickers, one for a base orientation on the object and then one for the target orientation.

Oops, that's a bug, thanks for reporting it. Should be easy to fix.

It's kind of a side effect of CPlane not really being a regular "Command" - one reason why it is not a regular command is so that you can actually use it while you are running inside of a command already.

Hi Eric, thanks for reporting the SketchUp problem.

It looks like a bug, it will take a bit of examining to see what the problem is, thanks for posting the example file.

One thing you can do right now to tune this up is to alter the model a bit. Right now the top planar face of your curved piece looks like it came from a sweep:



If you delete that top face (and the matching one on the bottom), then select the object that now has open ends, and then run the Construct / Planar command, it will create caps that are made up of simple 4-point planes that have been trimmed to that outline. Simple plane surfaces like that will export better to Skp format, it will become just one single face in the .skp file. (EDIT: same thing that Pilou mentions above)


Another thing is that SketchUp does not seem to like very long and skinny triangles very much, you may get some problems or also just a generally rough look to your model if there are very thin triangles in it, such as in this area:



There are some meshing settings that you can adjust to try and reduce that. One relatively easy way to tune it up is to enter in a value for Aspect ratio limit. Here I entered a value of 6 in there, which will subdivide polygons that have a long side more than 6 times the length of the smaller side. That results in this kind of a mesh structure instead:



Unfortunately that will also drive the polygon count up quite a bit as well and SketchUp is also kind of sensitive to that as well, so it isn't automatically always better to do this. But if you want a smoother look to shapes in SketchUp it can help.

Here is the result in SketchUp with simple plane caps and reduced skinny triangles:



I will be looking at your example file today though to see if I can find out where the problem is, it is probably something like SketchUp not liking to have duplicated points or points that are too close to each other in a polygon outline.

Unfortunately SketchUp is rather more sensitive to how its polygons are arranged than a typical polygon modeling program. It may take a few passes to identify situations that it does not like to handle.

Thanks for the tips Michael and French Pilou :)

I will remember this for my exports.

This was just a test (don`t really use SketchUp that much any more, sad but true).
I usually tweak my mesh exports, but didn`t bother this time, just wanted so check out the export function.

By the way, the curved object was not a swept curve.
I made it with the 3pts arch, extruded the curve, used shell, and then fillet on the edges.

I think this may be a SketchUp issue rather than a Moi issue.
The reason for this is that in the past when I imported geometry from other software (mainly acad/revit) there was always a lot of "cleaning" to do.
Must be some kind of tolerance/precision setting if I remember correctly, I got different results when I played with these settings.
Almost all the models and 2d plans were useless to model with, and I ended up just using them as guides/references.

Anyway, love the new options/functions, can`t wait to see the object organizer!

Thanks again for a killer app and support!


Eric

Hi Eric - it is definitely a big goal for MoI's exporters to try and eliminate the amount of tweaking and cleaning that has to be done.

It just saves a huge amount of time if the export is all clean right from the beginning instead of needing further work.

Of course with the very first release of a brand new exporter there may be a few issues to discover and tune up. It certainly helps a lot when I have an example to work with, thanks for posting it!

I've looked into that example and the problem is actually what I had guessed earlier - SketchUp does not like it when points of a polygon are too close together, it looks like when points of a polygon are closer than 0.001 units together it will cause SketchUp to flag the face as badly formed. That happens to be the case in some of those polygons along the top because the UV grid of the fillet is just a little bit different than the UV grid of that top flat piece. So when these 2 UV grids get combined to have a "watertight" outline for the polygon it has some points in it pretty close together.

For the next beta I will be able to solve this problem by merging points like that together.


> I think this may be a SketchUp issue rather than a Moi issue.

I guess so, actually I'm kind of surprised that it is sensitive to this amount of closeness, I would have thought it would have had to be a smaller distance for it to be a problem.

But anyway I'll be able to solve it in MoI's SKP exporter to not create this situation that SketchUp does not happen to like.

Congrats on the release Michael - I'm loving the cplane function!


Actually one thing I miss from back my Rhino days - would it be easy for you to add a right-click function to the Save icon to open the >export dialog<??

Typically I click the icon to save the .3dm version of a model.

To export, I have to go into the file menu to get to the Save As item.

Being able to right-click the Save icon and get the export dialog would bring that nice shortcut back. :-)

Michael,

Just a word to say i had export problems to sketchup : i work on a model this afternoon ( wood deck + wood fence around) : After the export i have lost the position of the fence compared to the initial deck position (around 30cm translation of the general fence) + i have lost the general scale of the model : 4cm in the MOI file was 9,3 cm in Skp.file.

I hope it is minor problems ...

Bye,

Pierre.
