CA50 is from volume 5, yes.

The bug should be fixed now. I had a function for getting the root of the file name that naively expected the only period in a file name to be the separator between name and extension.

The full color logo is actually quite nice, it gives the impression that this piece was important to get right, and warranted more attention.

You're really into making this garden leafless?

The resolution during export is the same as on screen, it picks the appropriate resolution based on the actual size of the symbol in the image. You can force it by selecting Very High before exporting, but it shouldn't normally be needed, as you won't get a benefit from using the very high symbol as a base if it is only going to occupy 10px in the final output anyway....

Ah, I see. It is just the name of a tool from that style. I don't really know the purpose of it, but it is just drawing a regular polygon. Mayby it is intended for drawing polygons that you can later use a cut operation against, but there isn't anything cutting or cutted in the tool itself.

Great it worked out for you. Smooth polys require more computer resources to render, so avoiding them on complex entities is preferable, but of course, depending on the map, one may want the slightly nicer look.

No, inlays.

Looks great, but you seem to have attached the image instead of inserting it into the post....

Just edit your post, remove the attachment, and insert the image using the image button.
