QGIS3 Shape Digitizing Circles is Drawing Improperly

Question

I'm trying to draw a circle in QGIS 3 with the shape digitizing toolbar. I've tried several of the "add circle" options and they all look normal while drawing, but once I click to finish the shape it is no longer a circle. Please see the attached photo. Any ideas on how to fix this so I can create circles?

Answer 1

You are drawing a circle in the coordinate system of the layer. Qgis reproject that circle to the coordinate system of the project, and that figure probably no longer looks like a circle.

You need to set the coordinate system of the layer to EPSG:3721 before drawing the circle, if you want to see it like a circle in the project CRS (EPSG:3721).

Answer 2

I've tried to reproduce your situation. 1. Created shape file in epsg:3721 2. Checked the same epsg for the project 3. Draw a circle at the same place

Here is the result

Answer 3

Update your layer coordinate reference system to match your project's.

You can do that by:

1. Toggle editing on the layer
2. Right click on the layer name and select Properties
3. Select Source
4. Under Geometry and Coordinate Reference System click on the select button and find the one that matchs your project (It's listed with the Project CRS prefix)
