How can I edit shape of square, circle and triangle?

[Tabunoki]

I want to edit the shape of forms which I create using the square, circle and triangle tools.

But, it seem not easy... it doesn't work like Adobe Illustrator.

How can I make the shapes like the image I attached?

Thanks for your advise

Hi @Tabunoki and welcome to the forums.

Contvert the shapes to curves. Then you can use the node tool.

Hi @Tabunoki,

Welcome to the forum

To do this in Designer draw you ellipse then convert this into a Curve by either right clicking it or from the Layer menu and select Convert to Curves, then using the node tool you can them drag the bottom node to create this shape.

To keep the shape symmetrical you need to constrain the movement to the vertical. To achieve this, hold down the Shift key as you drag.

Additionally / before: The existing "Segment" / "Tear" Tools might make it easier.

The Tear Tool creates a shape with a sharp point, so there’s more work to do if you want the final result to be egg-shaped.

… or just 1 click to smoothen this node

I didn’t say it was a lot more work!

Note that none of the above suggestions will by themselves create the open arc shape like in your first example. One way to do that is to first use Convert to Curves, then select the two nodes at the sides of the shape using the Node Tool, use Break Curve to separate that into 2 semi-circles, & delete one of them.

More work than it should be, like if we had a proper Arc tool....

I agree that proper tools would be wonderful (knife or scissors tool please)... But...

I would convert to curves then use the node tool and the Control key to delete one of the line segments and then delete the stray remaining lower node. Or use the node tool to delete the lower node and then Control + Click on the lower line segment to remove it.

I had forgotten about how CTRL-Click can delete a segment, but that works very well. Still more steps than it should take, though.

I would also like to see an Arc Tool with adjustable start & end angles similar to the ones for the Donut & Pie tools so we would not have to destructively convert to curves or cut anything apart to create simple circular arc shapes. Using a Donut or Pie with a 100% hole radius does almost the same thing, except that the width/height ratio of those shapes are not locked to 1:1, so they may not be true circular arc segments.
