I think I'm losing my mind. I just want to draw a simple arch shape with the curve tool so that I can extrude it into a solid. I can add a bezier curve, I can move the points around, I can move the handles, I can add and remove points. But I can't figure out how to do anything else.

  1. How do I make my drawing symmetrical?
  2. How do I connect the end points of the bezier curve to create a closed shape?
  3. How do I make sure that the curve has the correct measurements and proportions?

I just want to create something like the below but I cannot figure it out. I've spent hours searching how to do it and I just can't get it to work. I don't even really know how to describe my problem to search for it.

Arch made in CAD.

Let's go one by one:

  1. Add the Mirror Modifier
  2. Go Curve > Toggle Cyclic, shortcut: Alt+C (but it will mess with the mirror modifier)
  3. Use Orthographic view and enable Snapping to Increment (with Absolute Grid snap)

Add the Mirror modifier

Toggle cyclic curve

Set up Orthographic view (Front/Top/Side)

    $\begingroup$ Thank you for your wonderful help, I've got the curve drawn! Now I need to figure out how to convert it into a mesh. Object -> Convert to -> Mesh from Curve/Meta/Surf/Text just creates a duplicate of the curve, though it has the inverted triangle "mesh" icon next to in the collection. $\endgroup$ Mar 18, 2020 at 4:28
  • $\begingroup$ That's exactly what should happen :). Now you can hide the bezier curve, select the mesh and extrude it. If you get lost, feel free to ask a new question :). Good luck. $\endgroup$ Mar 18, 2020 at 10:02
