Transparent FIlls for Zones

Eric B — Fri, 22 Aug 2025 07:08:06 GMT

I know this has been discussed in the past but I am trying to make the fill on zones semi transparent

I thought I could do this but creating a Graphic Override and change the fill pattern to 25% and the background pen to 0 - This all seems logical

However when I do it all of the foreground pens change to a single colour and they do not retain the zone colours. It is the only Graphic Override applied

I could of course done something really stupid as well

See the attached screenshots

Any help would be greatly appreciated

Cheers

Hi Eric,

To be honest I didn't really understand what are you trying to achieve.

Here are zones with no GO, with their cover fill at 25%, transparent background

Now if I wanted to override them with a red hue, I just override the fill foreground.

does this answer your question?

Edit: or do you want to override just the background? I tried that and strangely, it doesn't override only the background pen.
edit2: I have tried and the GO works on any type of a fill that does not use a transparent background. if that is used, the override won't work.

The % fill and zero background pen will give you a semi-transparent fill.

But I don't know of any way to keep the original zone colour.

As you have noticed, the foreground colour changes as well.

You can control it with the foreground pen, but all zones will be the same.

You could set up separate rules for each zone category, and match the foreground pen with the colour of that category.

Then in the override combination, you add each of the rules for each category.

I hope you don't have too many zone categories.

You can override the cover fill in the zone settings, but this will be in all views.

You still have to set the foreground pen colour as well otherwise they will all be the same.

Using the Graphic Overrides allows you to have different looks in different views.

Thanks guys

I have a few schedules set up for reporting different areas, perimeters and volumes of zones and the I was wanting to use the zones to draw over different parts of the floor plan (or in some instances the entire floor plan) but I still wanted to see the floor plans underneath similar to the image

Layered Zones

While I understand the colour will not be exactly the same when you apply a % fill I was hoping a tint of the original colour assigned to the zone would remain eg: because you weren't changing the foreground colour it would remain as set for the zone and by making the background colour (0) and the fill type a % it would at least make the zone semi transparent

Yes Barry .. I could just create a dozen GO for each zone but seems a little excessive. For now I will take the extra step of assigning the colour to the zone and the the cover fill to achieve the same outcome and not worry about GOs

Thanks for your help

Eric
