It's so nice to have this concept in it's own video! I know you mention these things a lot but I always forget among the other things I'm learning about the blue lines and lock icon. 🤗
On every one of your videos, I do learn something new. A big trick or a little one, but always I get something for my Fusion toolbox set. Keep it on with the hard work, man!
Great as always. Something for your consideration: Rather than draw a line from the midpoint, then make it construction, I find it's less cluttered to just drop a point at the midpoint and then make the circle centerpoint horizontal from that point. I use points like that so frequently that I have the point shortcut on the toolbar. It's less clicks, and the drawing is easier to read without a bunch of lines.
You sir are a genius. I was having trouble constraining that circle on the left with the contruction line. Even though I was doing everything exactly it would not constrain. Making a point and making it horizontally constrained fixed it immediately.
Good video ! I definately scratch my head trying to get sketches fully constrained somtimes,takes longer that extruding and addling all chamfers and other bits !
It is a nice video for your new course and also making the drawing fully defined without using dimensions too much. (Note: Please answer my question about Lesson 4: Designing Headphone video. I have a problem and couldn't fix it :)
I guess it depends on what you are designing. Most of my 3d prints are for holders (tools, drawers etc) and are mostly one of a kind. I never take the extra time to fully define my sketches and have never had any problem with my designs. I also usually hide the dimensions, points and constraints.
You make great videos, but I'm still having the issue that all lines are black, but there's no lock. Can't find anything blue. Also some lines turn red (around holes in the sketch) when selecting some sketch profiles in the main editor. You see this when lofting. Don't know why.
Me too! You have the best videos on here by far! I have a sketch with way to much going on and its all black. I grab a corner to shake it to see what breaks, fix it, then shake it again. Now I cant get it to break and it's still missing a constraint. (says so in browser) As soon as I copy it into another sketch it breaks. (I use all internal constraints. I use parallel and perpendicular instead of horizontal and vertical and all my dimensions are relative to 1 internal HARD number. Is there a way to highlight bold or search for unconstrained points? Or hide all fully constrained parts? Thanks!!
How does one design springs and compliant mechanisms? Are there any calculations one must do beforehand? Edit: I am asking for a compliant spring return check valve & binary (compliant) rocker switch, both 3d printed of course.
Hi, Glenn. Fantastic question :) Splines can be fully defined by dimensioning and constraining all of their spline handles/points. However, in many cases, this is simply not worth it. Especially because splines are often fine-tuned as you continue to work on your model. The best practice with splines is to use the "Fix" constraint. What I recommend is fully-define thee entire sketch with normal dimensions/constraints per the best practices. At the very end you will then want to add a fixed constraint to the spline geometry. That will turn it green and lock it in place, while the lock icon appears in the Browser.
@@ProductDesignOnline that's great I'll definitely try that it's been plaguing me because it's such a waste of time dimensioning all the points. you have to do the angles of the handles too., it looks horrendous.
SVGs are automatically "locked" by the Fix constraint upon inserting them. You'll have to make sure any other sketch entities are fully defined as well. You can also unfix the SVG and try to "Fix" it again to make sure that it's all completely locked down.
Is there any way to keep the sketch fully constrained when saving and importing as a .dxf? When I import sketches to use for repeatable extrusions they come in un constrained so I have to constrain it every time.
There is not, unfortunately. Imported DXF files are converted to sketch geometry behind the scenes. The problem is that curves and specific shapes often become small line segments. In those cases, it's best to delete the small line segments and recreate with constraints.
Sadly, I thought that was the case. For what I am doing its probably best to import a whole part. Thanks for the reply, love your videos!@@ProductDesignOnline
Hi Michael. The sketch tab is 'contextual' meaning it will only show while in the sketch environment. You will have to either "Create Sketch" to create a new one, or you can edit an existing sketch. You will then automatically be placed in the sketch tab.
@@ProductDesignOnline Thanks for that. It helped a lot and makes perfect sense. I last used CAD in the 80's and it was ll 2D. 3D CAD has some "nuances" that I'm still trying to figure out.
I love your videos but I keep running into the same issue which is sometimes my circles will not fully define. I follow all your steps to a T and when I try to put the midpoint line to the center of the circle it just won't define, the circle stays blue. I have all the same constraints on my diagram as you do. imgur.com/gallery/JsSgrUx

Kevin, thank you for such a short but concise video - I leaned a lot in a very short time . Great tutorial!
searched over 20 videos for this simple solution. thanks
It's so nice to have this concept in it's own video! I know you mention these things a lot but I always forget among the other things I'm learning about the blue lines and lock icon. 🤗
Symmetry make more sense now! Thanks

Thanks, Johnathan! Glad to hear that. Happy learning :)

(Note: Please answer my question about Lesson 4: Designing Headphone video. I have a problem and couldn't fix it :)
My problem is that when I try to put constraints to my sketches, it says it's over-constrained and doesn't allow me to make them black. Any help?
Can you share a specific file that you have in mind? That will help me give you a more specific answer to your use case :)
Excellent video
I don't even have fusion but love the concept.
Thanks for this great video and please Make video on rendering .
I guess it depends on what you are designing. Most of my 3d prints are for holders (tools, drawers etc) and are mostly one of a kind. I never take the extra time to fully define my sketches and have never had any problem with my designs. I also usually hide the dimensions, points and constraints.
Hi Kevin, Do you have any videos concerning the simulation workspace? I really appreciate your style and content... Thanks you!
Hi Dan. I do not at the moment. I will try to do some in the future 😉
Thank you..

CONSTRUCTION geometry must also be defined. As I learned.
How does one design springs and compliant mechanisms? Are there any calculations one must do beforehand?

Thanks but How you define a sketch with splines in it?

Whenever I add an SVG to a model. That sketch is never fully defined/constrained. My sketch only contains the SVG. How do I fully define the sketch?
SVGs are automatically "locked" by the Fix constraint upon inserting them. You'll have to make sure any other sketch entities are fully defined as well. You can also unfix the SVG and try to "Fix" it again to make sure that it's all completely locked down.

How do you get the line option? I also don't see sketch on my menu bar. It stops at Tools

Found my problem at 4:50 if it saves anyone some time

Fusion 360 makes what should be simple, so unecessarily difficult.
Are you referring to the placement of the red lock icon ?
