Hey Michael,
THanks for the update. I'm getting an "Invalid Error" message when I try to download.

Hi Vladimir, I will reply in the other thread I split your topic off to, over here:

Was playing around with the Boolean Merge tool and may have found a bug whereby one of the newly 'Merged' parts instantly disappears after creation. If not a bug, then why does that particular part go missing?

Here's a very short video I made of what happens.

Hi Martin, that's actually how boolean merge is meant to work when open surfaces are involved. When there are open surfaces it will try to extract all closed volumes it can and remove the exterior surfaces, there's another example here: http://moi3d.com/3.0/docs/moi_command_reference7.htm#booleanmerge , see the one labeled "Boolean Merge can also be used to extract a common solid volume from a set of intersecting surfaces:".

> If not a bug, then why does that particular part go missing?

It's because it's an open surface and not a closed volume after everything has been intersected and merged.

Thanks for explaining that for me, Michael.

I didn't need that particular bit, but could you tell me if there's a way to retain those parts in case you wanted to use them for something later, please?

Cheers, Martin.

Hi Martin, one way to keep it is after you see that it's gone use undo to go back a step so it will reappear then select it and use Cmd+C to copy it to the clipboard, then redo then Cmd+V paste. That's kind of a general purpose way to keep something that was removed by any command.

Or another possibility is to use boolean difference with that surface as the cutting object, there is a "Keep objects" checkbox in the command options that you can use for boolean difference where it won't remove the cutting object.

By the way I still have it on my list to investigate the file dialog thing you wrote about way further up in this thread I just haven't had a chance to do the testing for it quite yet.

Hi Michael,

i like to ask if you already found a solution for creases with the subd to NURBS feature,
or is it something you thinking about, once MoI v4 is released?

Best regards
Stefan

Hi Stefan, I'm going to be looking into support for creased edges after v4. I want to get things ironed out with regular non-creased stuff first.

Hi Michael,

thanks for the information!

Best regards

Thanks so much for creating V4! It works so much better than V3. I create LED displays with 1000s of LEDs, each represented by a tiny solid. I used to wait minutes for each save or open. Now it's so quick. Thanks again!

I have one super quick and presumably easy feature to request as you move from platform migration to new features: An option to have object selection and creation clear the previous selection.

I can't tell you how many times I've accidentally deleted valuable objects in processes like this:
• select some solid and do something with it
• pan the view somewhere else
• draw a circle
• extrude the circle to make a cylinder
• hit the delete key to delete the circle

Hey wait a minute! Where's my original object? It's gone because I didn't remember that it was selected when I drew the circle. (One could argue that allowing the extrude command to function at all when a solid was selected is a bug.)

I strongly feel that selecting an object without modifier keys, or creating an object should clear any previous selection. This is the way that (probably) every other object-drawing program works. Its the way all word processing and other types of GUI programs work too.

Since having selection and creation ADD to the current selection is the way that MOI has traditionally operated, I know you can't just change it, but PLEASE provide a setting in Options to have selection work the way a lot of people, including myself, expect it to.

In this optional mode, please make it so that holding the shift key while making a selection DOES add to the existing selection, both when selecting an object in the rendering and when selecting all objects of a given name/type/style. ie: Holding the shift key takes you back to MOI's traditional selection style.

Thanks again!

Hello,

Esc is your friend if that happens to be your workflow. From a UX perspective how MoI selects and modifies objects in space is, in my opinion, one of it's greatest strengths. Many other design packages are hamstrung by lack of usability improvement in that critical area or try half baked implementations that slow down this frequent process. Asking a user to remember a more complex operation leads to confusion and frustration with a product.

Hello Christopher.

I agree with you, it is always necessary to remember, and Yes, the Esc key to automatism.
I often find myself in this situation too.
This method in one case it helps, the other hinders.

Vladimir.

Thanks Christopher, I'm glad you are liking the improved file loading speed in v4!

re: Multiple select - I do have it on my todo list to put in an option for changing how multiple select works like you are describing. I haven't been too excited to do it kinda because the way it currently works was one of the very earliest design choices for MoI to enable working without needing to constantly use the keyboard. So turning it off is to me kind of a little like taking out a piece of MoI's soul... But only a little. ;) I think it will also be somewhat problematic when you're working with edge or face sub-objects where multiple selection is needed almost all the time. That's an area of MoI that does not really resemble a 2D drawing or word processing application very much unlike curve drawing.

Hi Christopher, also re:

> (One could argue that allowing the extrude command to function at all when a solid was selected is a bug.)

At some point here hopefully not too far off having a solid selected at the same time as a curve when you are doing an extrude will mean project the curve onto the solid and extrude that piece of the solid in or out.

Why not a Nurbs to SubD converter?
