DL and non-squarish rooms

I need to make a round room which has a door in it on the right-side and a corridor on the left-side. So actually there is corridor-round room-corridor but there is a door just before the right-side corridor starts. Can I do this with DL and not use free-hand drawing? What was about to do was to make a circle and the just rubber out the points where the corridors start but there is no eraser.

Yes, the best way to do this is by making a circle using the Polygon/Line tool. If you need help let me know.  - Gauss

How do you do a circle with that? Really appreciate your help.

Set the roll20 zoom level to 150%. Set your browser zoom level to 150-300% (the higher the zoom the finer the details possible).  Start a line, it will need to be about 1/2 of the size of a square before you can start turning the line. Draw small incremental lines and change the angle of each line until it starts to form a curve. When you are happy with the overall curve, right click to finish the polygon.  Note: since you are doing a circle it is possible you will end up too close to the starting position of the polygon. If you do it will 'autocomplete' the polygon and draw a line you do not want. Right click before this happens to finish the polygon. I often work in segments due to this reason.  Below is an example with the zoom is set to 150% in Roll20 and the browser is set to 150%. - Gauss

Ok, thanks.

An additional advice to all. If you want to make a round, half-circle, etc. areas. Draw a circle on GM layer. Then go to map/DL layer and draw an overlapping line using the methond Gauss explained above. If you like, go to GM layer and delete the circle.

Good idea Maetco. Normally I am matching existing map features so that is not something I need to do but if someone did not have map features to follow it would work very nicely. - Gauss
