Point to Point

[TimelesslyTiredYouth]

I'm 3d sketching some stuff and when I'm just about to loft from line to line and use a guide rail, I realise the guide rail is not intersecting one of the lines. I immediately though to just link the end point of the rail line to a point on the other line, but I didn't know what to do...

i tried a coincedent constraint, but I realised it only works on a 2d scale, is it even possible to add constraints to 3d sketches

Sorry for the begginer question, I'm not that great at fusion.

here's a quick example, which is basically the same problem I'm experiencing in the original file, however I can't share it as it goes over the upload limit by quite a bit...

*I also noticed that allign only does line to line or side to side, but theres no point to point feature, or am I just being special?

I'm doing this while surface modelling if it helps...

Hi,

please share the file for reply

Move Tool, has Point to Point.  
I don’t draw 3d sketches, I make Fusion give them to me.

Might help…

yes. constraint does work in 3d sketches.

don't know if it's related, but but if you're actively editing a sketch in the pic you posted, neither of those lines are in the current sketch, so yo won't be able to apply a constraint to either.

[TimelesslyTiredYouth]

so the point I would want to coincedent constraint would have to be in line with the sketch plane?

[TimelesslyTiredYouth]

Move tool, that's how I've been moving the point, but how will it help me get the points to snap together, or at least touch, snap preferably

and what do you mean when you say you make fusion give them to you with 3d sketches?

*the move tool is just a trial and error process of getting the points touch is it not?

The original file is too large, this is just a random new project I made to show the problem.

Then create the situation in a sample file.

Hi @g-andresen 

Currently have some CPU intensive software open in the backround, can't open fusion at the same time, it would be too much.

It's basically two lines on different sketch planes. I want to snap the end point of one line to the mid point of the other line, but I can't use the coincedental constrain in this situation due to the fact that the sketches are on different planes, so I don't know what to do as the move point function is just a trial and error to get the points to touch, but I need them to snap together in some way like when we constrain a sketch. and snap together two points, i need to do that in a 3d sketch environment somehow...

First, when you want to move point-to-point you need to use the move tool and not the align tool.

Second, sketch constraints can indeed be applied for 3d sketches, you just need to 3d-include both profiles before creating the rail, that way you can make sure it's touching both profiles, not to mention that you can create dimentions in 3d sketches, which is also a type of constraints.

I've attached a simple example showcasing that.

Quick tip : if you turn on the "show dimension" option after finishing the sketch by right-clicking it from the sketch folder in the browser, you can edit the dimensions without the need to enter the sketch or change the dimensions from the parameters menu.

Fusion requires that you can only snap to things I. The current sketch.

If articles are not in the current sketch snapping behaviour is random, sometimes it works.

Use (for 3d sketches) Create, > Project> Include 3d Geometry.  This will copy the article into the current sketch.  Snap to the purple articles does work.

Fusion supplied.  If you were to create an intersection curve, two 2d sketches used to create the 3d sketch, (Project > Intersection curves).  I use Surface tootles and extrude/ Sweep etc, and trim to obtain body edges that are 3d.  Selecting trimmed helper bodies, gives better curvature than any projected purple article.  Takes a while to get used to it, but way better results.

Might help….

Yeh I agree, just trying to get better with surface bodies and found this problem while i was trying to 3d sketch something so that I could eventually use the patch tool and loft tool to start piecing together my work, provides much better results and probably much faster, even though it requires the a skeleton at the start.
