Can you show us a screen shot of the Bevel effect in edit mode, so we can see how it is set up?

Perhaps that is a bevel?

I was having reception issues in that moment with slow broadband, but the usual way is by Insert File in the Draw menu.

Yes.

If you have any questions about specific symbols or fills you have modified, and which you wish to share with others, it is probably best to contact PF directly using the Licencing Questions email address on the Contact Us page: https://www.profantasy.com/service/default.asp

However, this is about giving the symbol itself away. You can use all the modified symbols and fills that you have made in your own maps, whether or not they are commercial. It's just the individual assets.

That is what the colorize effect does - sets the colour.

The HSL effect works with the colours as they stand, so that if you have a blue rooftop you can change the hue by increasing or decreasing it around the colour circle, increase or decrease the saturation of it (that one is the wrong way around for my way of thinking, since negative numbers increase the brilliance of the colour). Lightness is the easiest of the controls, being reasonably self explanatory.

So whatever colour your roof is, these settings would make it 5% further along the spectrum (for example if you start with blue it will go more violet). With the Saturation set to -10 that will make the colour of things on that sheet 10% more garishly bright, and the Lightness value will make them darker by 30%.

This is an adjustment, rather than a setter. It's like messing with the settings on your monitor.
