AcrobatProで図の面を塗りつぶしをしています。その塗りつぶしの一部を塗りつぶしを解除したいです。イメージとして図面の壁面を塗りつぶし、窓だけ塗りつぶしなしの状態にしたいです。私が使用しておらず関係会社からの問い合わせのためイメージのみのお伝えですが、知恵をお借り出来たら嬉しいです。よろしくお願い申し上げます。

Adding color to the wall while excluding the window is a task better suited to Illustrator (the pathfinder tool). You could use the Acrobat comment tool to draw a closed polygon around the window, add a fill color and change the stroke style to "none" (right click on the comment and adjust the properties). the polygon can overlap itself to simulate the window being cut out of the shape. You can use a preflight fixup to convert the comments into regular page content, if desired.

Hi there,

 

Hope you are doing well and sorry for the trouble.

 

It sounds like you’ve used the Fill & Sign or Drawing/Highlight tools in Acrobat Pro to color parts of your diagram, and now you’d like to remove fill from specific areas (like windows) while keeping the rest filled in.


Here are a few ways you can do that:

If you used the Drawing Tool (Comment mode):

  • Go to Comment > Select tool (arrow icon).
  • Click on the filled area you want to adjust.
  • You can either delete it or right-click > Properties to change the color or opacity.
  • To leave “holes” (like windows), you’d need to carefully draw around them instead of over them — Acrobat doesn’t currently support “subtracting” from a fill area.


If you used Fill & Sign:

  • Fill & Sign fills can’t be partially erased. You’ll need to undo (Ctrl+Z) or delete the fill and reapply it more precisely.


Alternative option (more control):

  • Export the PDF as an image (File > Export To > Image > PNG or JPEG).
  • Open it with any image editing app, fill the areas you need, and then reimport it back into Acrobat as a new PDF. This allows you to mask out (unfill) windows cleanly.

 

Hope this information will help
