I want to use "capture polygon" function in QGIS software to draw the indoor office cubical which is a rectangle shape. But the "capture polygon" function is not able to draw a perfect rectangle shape. How to draw a rectangle feature in Qgis software when you are creating a feature?
You can chose between CAD Tools plugin which is more complex and more powerful,
***This is my add-on: after install the plugin you may have trouble to locate the plugin tool icon or buttons. Please look for the plugin tool icons on you Qgis software panel, they are probably in grey color. I attached the photo as below.
