this was already probably a bit of an annoyance earlier to me, but someone brought it to my attention.
on the left, you've got a screenshot of a drawing on a layout with a break-line object with a masking fill covering the rest of the slab section details.
on the right, you've got a screenshot of the same drawing in PDF, & you'll see a most of the masking fill covering the slab section detail except when it gets to the boundary of the drawing -- where you'll see a bit of the covered model poking through the drawing boundary. it's thickness depends on the thickness of the pen used for the line / cut-line. the only fix we found for this was to add ANOTHER masking fill in the layout just to cover this protrusion. i even tried adding a white line boundary around the drawing & the black dots still pop-up. no matter if i put the masking object/fill to the top of the Display Order, the dots still appear.
is there a fix for this?
You have to extend the white fill past the end node of the line you want to hide.
The thicker the line, the further you have to extend the fill.
Lines have round ends that extend beyond the line node by half the width of the line thickness.
It is a bit odd that it seems to be hidden in your layout but still shows on the PDF.
Usually it is WYSIWYG (What You See Is What You Get).
Maybe zoom in more on the layout and you will see the line also.
screenshots are from the layouts
the attached file is a PDF of the published layout. i used other elements that can replicate a 'masking fill'.
in the second drawing, i've cropped both ends to where a masking fill is supposed to cover the thick lines. masked by either the object, fill, slab or even the text with a background fill.
you'll notice that the lines still poke through as dots in each instance -- even with the 2D text. immediately after the "c" for 'breakline object" & just above the first "L" for "slab with cover fill".
I can confirm this does indeed happen in version 22 (haven't tried later versions).
I am not sure why it does this.
Even though you have stretched the drawing frame over the white fill from your masking break line, the end of the hidden lines still show through beyond the extent of the drawing frame.
I even drew a thin line at the edge of the drawing frame - there should not be anything extending beyond it.
Especially seeing as the lines are completely covered by a white fill anyway.
The only work-around I can suggest is to place a white solid fill with a white perimeter (or no perimeter) over the top of the edge of the frame on the layout.
Archicad has been like this, for as long as I recall. You need to mask off the whole thing and show the whole masked area on your layout. If you trim the placed drawing across the mask, you get these 'dots' as you fittingly call them.
Doesn't make sense, but I learned to live with it...
Other than adding a white fill to the layout, you may be able to do this.
Stretch the breakline mask over the entire end of the slab.
Now when you place the drawing on the layout, do not drag the drawing frame over the mask object.
Leave it stopping short.
As it is not going over the mask object you will not see the 'dots' any more.
If there are other bits you need to crop off then you can create an irregular polygon frame and just stretch it around the mask object.
