Hi,

Maybe it could be nice if tweaking points of a 3d curve would be constrained by the view instead of cplane....
Maybe as an option?



There is also the option to blend lines in 3d space, which is quite useful to explore 3d curves.
You can move the generating curves or it's points afterward and blend will follow.

Danny - that's pretty awesome ! I was actually originally referring to sketches as in, rough sketches from the front, side and top views, but the example you linked is even better :) I did try it and it does work ; I just had a few issues with the freehand sketch tool Repeat option turning itself off, and also the CPlane alignement options felt a little rough for the sketching process to be really fluid (I still have to experiment further - Ideally, a great way to orient the CPlane in the context of spline sketching would be to pick 2 points in space, then rotate the plane around this line direction until it reaches the desired orientation. and then of course, being able to incrementally move the CPlane in XXZ (world) and in a freeform manner in perspective. A CPlane manipulator could help too - but that's a whole other can of worms :D)

Marc : yeah, pretty much - simply being able to move existing points (and full objects too) in view/screen space would be a sweet thing to have (having real time scene mirroring too, as it would make the whole roughing out process pretty brilliant). But yeah as Michael pointed out it might not fit with the overall and current goal of MOI. But then of course there will always be people bending the rules and using the tool in unintended ways :)

I thought I might aswell resurrect this topic again now that v4 is in dev.

Here's a good example showing someone with a ton of experience with the program, yet still running into the same issue that I run into when it comes to screen space placement of objects/components :

https://youtu.be/lmiCOGKZ7q0?t=180 (3:20 shows the result being very different from what the user intended, leading to him having to undo and try again from another angle more favorable to the transformation he is attempting. Screen mode would completely bypass all that :) ).

I think this is a good example showing that even when embracing the "CAD-like construction" paradigm of MOI, one would still benefit from being able to adjust the position of components in screen mode, without any other constraint.

I hope this makes sense !

Hi Pior, well v4 is at the very end of its development cycle so it's not really a time for experiments right now. There is a lot of information earlier in this thread about why screen space manipulation isn't currently a focus for MoI.

Hi there Michael ! That does make complete sense of course. If anything I am glad to have at the very least brought the topic to your attention.

So, without going the route of a screen-based manipulation mode ... is there a way at this time to display some sort of direct world space XYZ manipulator, at the very least ? (I actually tend to avoid the use of manipulators in 3d software as I find them distracting, and tend to rely fully on kb shortcuts instead whenever possible ; but in the case of MOI I do believe that a simple barebones Move manipulator would help quite a bit.)

Either that, or maybe a script/command that could be assigned to a shortcut, allowing to move a selection by a given amount of centimeters on one specific axis (as opposed to having to manually activate and use the regular move tool, or having to go into an ortho view to grab and drag there).

Overall I think this is the common underlying topic of my remarks (both this one here as well as the one about the unneeded highlighting of components) : the MOI UX design is very proactive when it comes to walking the user down the branching paths of possible inputs (for instance : clicking a few times to gradually go down from object mode to edge or face mode ; or similarly, having the user "hunt around" the screen with the mouse until the desired X, Y or Z Straight Snap axis gets selected). But in the case of a user knowing *exactly* what they want to do beforehand, this paradigm gets mildly frustrating because it introduces unneeded options interrupting the flow state.

For instance : if I know in advance that I want to move a selection up on the vertical axis, being presented with 2 other directions picked up by the Straight Snap mode along the way gets irritating because in my mind these options were already ruled out - therefore having them flash on screen somewhat gives the impression of going backwards.

It's a little hard to explain but I hope this makes sense !
