SHIT.
Corel Draw?
Daaaaaaamn, bro!!! That is some dedication. You gotta work with the tools you know (or that are available) though, eh.
Quite a trip on the wayback machine seeing that. Next we're going to have someone here doing all their maps in Fractal Painter Pro
Well in my defense CorelDRAW is still being updated yearly.

Although for a couple of years, the company that owns it has been trying to milk it for cash hence I only update every four to five years.
Even tho I pay for Creative Studio, I still stick with CorelDraw mostly because how it handles fills. From what I tried in Illustrator you have to turn objects into masks that crops out a large bitmap you hide in your drawing. I kinda get it, but CorelDRAW handles a fill, whether it is solid, a bitmap, vector, etc., a property of the object itself. So much better. Certainly Illustrator's approach is less memory intensive which is why they probably adopted it in the first place.
One reason fills are important to me is that I collect old dry transfer sheets and scanned them. I focus on the ones used by Judges Guild and the old Wargaming companies to make their maps.
From here
In the 2000s I bought a CD full of scanned images from LetraSet one of the few surviving art supply companies who made these sheets. Then later I found a store on Etsy that also sells them.
Shop Vintage rub on dry transfers & screentone by craftytransfers located in Stanford, United Kingdom. Smooth shipping! Has a history of shipping on time with tracking. Rave reviews! Average review rating is 4.8 or higher

So I bought a dozen or so to fill out the gaps in my collection that I bought from Letraset.
If you have a copy of Melan's Xyntillian, you can see how I use them, particularly on the first floor.
One major thing I am missing on CorelDraw are Illustrator style brushes. Specifically the type that allows you to draw vector objects in a line. With Corel it a lot more difficult for me to do that.
For example the below map, the Harn folks with Adobe Illustrator can just pick a brush and draw the walls with the proper endcap with a few click.
For me, the above was a bit more convoluted, and the result was a bunch of separate objects, making later editing a pain. So may yet buckle down again with Illustrator and figure out how to use it to draw my maps.
The last thing I want to mention is Inkscape, which is free and open source. If Corel Corp gets that bad, I know how to use it to do my maps, although its brushes are not on par with Illustrator's. But for someone who want to learn vector map creation and not invested in the pricier options it is a good choice.
Inkscape is professional vector graphics software which runs on Linux, macOS and Windows desktop computers.
