Working with constraints in FreeCAD sketcher.

In this video we cover the constraints in sketcher. By showing a methodical approach to constraining sketches you can see that almost any sketch is "constrainable" (invented a new word). Not all sketches need to be constrained but if you are going to use it for modeling I strongly recommend it.

Another great explanation, thanks!

[@Adventuresincreation]

Thanks for the feedback.

[@wisefix9256]

Loved this tutorial. Clearly narrated (hate silent tutorials), step-by-step with lots of attention to detail and explanations as to the why of things. As a newbie, I really appreciate your style. Clearly you care more about sharing the knowledge than to showcase your (evident) modeling prowess. Subscribed!

[@Adventuresincreation]

Thanks, I try to help everyone enjoy using Freecad

[@paulg3336]

Nice tutorial. A tip for efficiently constraining vertices (points) in the horizontal and vertical ,is to use the lock constraint. The lock constraint automatically creates both a horizontal and a vertical constraint for the selected point.

[@Adventuresincreation]

Thanks for the feedback. Love the tip. I'll mention that in another video. Thanks!

[@funkysod]

On the same note when constraining points refering the origin just select the point and constrain horizontal or vertical length. If only one point is selected freecad automatically assumes you're refering to the origin. Those clicks add upp quick! Thanks for sharing!

[@Adventuresincreation]

Excellent, thanks

[@keithschaub7863]

keep up the good work

[@Adventuresincreation]

Thank you, I will do my best.

[@zuheyr1]

Hello, thank you so much! It is wonderful. Tell me please: concepts horizontal and vertical are only defined in X-Y plane? Thank you!!

[@Adventuresincreation]

Each plane has a relative horizontal and vertical space

[@mostirreverent]

is there a way to draw shapes, and have the constraint dimensions already attached, so all you have to do is enter the values? Are there rectangles and/or lines that have center points without having to add them?

[@Adventuresincreation]

Take a look at the part workbench where you can create primitives that you can alter the center and dimensions before they are constructed

[@mostirreverent]

how did you make the construction line? Is it a separate tool??? Ive been making lines, and then changing them into costruction lines.

[@Adventuresincreation]

If you hit the button 🔳 that turns them into construction lines before you create the line it will be a construction line.

[@gregpruitt1647]

This seems messy with having to address every one of the elements. Is there no way to lock all the elements together in one action?

[@Adventuresincreation]

No, that's not how it works.

[@davidhealy6589]

HI, I've drawn a part and it is fully constraint and now I am mirroring the part and I see that the new mirrored view is un constraint is this normal or is there another way to do this? thanks Dave H

[@Adventuresincreation]

Are you mirroring the sketch? With freecad you can make the part and mirror the feature.

[@davidhealy6589]

@@Adventuresincreation Thanks for reply, Yes I'm in the Sketch workspace. are you suggesting that I creating a part first and then mirror it? thank you your videos are great

[@Adventuresincreation]

@@davidhealy6589 yes, try creating the model geometry and mirroring it in the model. I usually do it in the part design workbench

I'm working with FreeCAD 0.19 v and trying Boolean cut for some reason I've not been able to cut the part

[@paulg3336]

I'm just guessing here, a common problem is not selecting the bodies in the correct sequence. In the part work bench, click on the boolean union tool and a list of bodies will open in the task panel on the left. You will see 2 lists ,one labelled "First Shape" and one labelled "Second Shape" You can then make your selections and what boolean operation you wish to use there and change it and see how it all works.

[@lakshminarayanaaithal1081]

@@paulg3336 Thank you. I've selected both bodies in order(First shape and then second shape-Padded sketch). Still, it doesn't.

[@paulg3336]

@@lakshminarayanaaithal1081 I suggest you create a new file. Go into Part WB and create a couple of the primitive shapes ( a cube and a cylinder for instance ) and experiment as I suggested earlier, making boolean cuts and unions etc. It may lead you to find out what the problem is. It may be because the parts are not separate bodies or some other reason.

[@lakshminarayanaaithal1081]

@@paulg3336 Okay will try.

[@Adventuresincreation]

I agree, that is a common mistake.
