I have a drawing with dimensions etc, but a couple are missing one extension line, even after re-opening drawing & re-dimensioning (if that's a word).
Please see attachment to see what i mean.
is this a software error, or something to do with the graphics card?
Asus Laptop, Win8.1 Pro, SW 2016.

Intel HD Graphics 4000
nVidia Geforce GT 635M
Thanks for replying Habib,
i can't find the option "Show extension line" in the context menu, where are you finding that option?
(There is the option "Show dimension line", but that doesn't work.)

If you right click the dimension you will see the option.
If it doesn't work, maybe it's because it's not hidden and something else have caused it not shown.
As you can see there is no "Show Extension lines" option...
It IS in a detail view, but surely that wouldn't make a difference....?
Also i notice in your screenshot you have one line missing too?
I have also noticed that when doing detail views, what I did was just add a small line or a sketch point and dimension from that.
This may be a dumb question, but have you moved the line farther away from the geometry? The extension line may be too short to display at that location.
This is a bit of a bug that I have noticed on cropped views. The dimension "thinks" that the line you are dimension to extends past the cropped portion.
Sometimes, just editing the crop works to fix the problem. And sometimes I have to recreate the crop altogether.
Thanks Scott, yes i tried that, and no i doesn't make any difference.
Thanks for your reply Jeff
What do you mean by 'edit the sketch of the detail so the WHOLE view is shown'?
FYI: I asked my colleague to open it on his computer, and it was the same, but when he re-dimensioned it, they worked fine!
I am using SW 2016 Service Pack 2.0 and he is using SP4 so i'll update and see that fixes it.
Oops there was a comment by someone named Jeff before, but it disappeared after i replied to him!
If you drag the dimension farther away from the geometry, does the extension line appear? I've seen that behavior before.
As you can see, this didn't help either. It exports to PDF like it as well, its not just a viewing anomaly.
Also, I got my colleague to re-dimension it and it was fine, had both lines, but when i try to re-dimension after, it still would only show one extension line!!?!? very strange. I will be updating to SP4 or 5 this afternoon so i'll see if that fixes it, and let you guys know.
thanks for all the helpful suggestions so far.
The only suggestion I can make now is to "fake" it by drawing a sketch line coincident to that left model edge and dimension to that instead of the geometry. Not ideal but worth a shot to get 'er done.
This is a known issue, see SPR #837039
I've found that it depends where you right click on the dimension to what popup you get. If you click on the extension line you should get the correct pop up
I've voted for the SPR even though it is written as implemented in 2016 A1. I have had this issue, although I work around it. It's not just dim lines, it also happens with datum leaders.
You have probably found the solution by now, but here is my input anyway. I was dimensioning a detail view, I added a centerline, add tried to dimension from it and I noticed that one of the extension lines was missing no matter what I did. Right click and show extension line didn't work, however, when I moved the dimension very far away from geometry, and tried right click - display options-forshortened option was checked. I unchecked it and it worked. I did it couple of times, sometimes it worked when I moved dimension farther, sometimes closer. Where to click also matters.
I hope it helped.
I'm using SW 2016 SP 2.0
I was running into the same issue. Not sure if you have this option or not, but if you delete your dimension and re-create it, then do a right click, display options.... there was a foreshortened option checked. I unchecked it and it corrected it for me. Odd thing is, once it is unchecked, I don't see the option to toggle it back on.
Is the dimension created by selecting lines (edges) or points? Sometimes when this happens to me I re-create the dimension by selecting points only instead of edges and the problem goes away. Weird I know but it works....
Very good point! I noticed the same behavior.
I use 2016 and there may have been a fix after that but what I do when I have this situation is right-click on the cropped view, choose 'Crop View> Edit Crop'. Drag your boundary that's near the missing extension line a little farther from the geometry. Recreate the dimension and the missing extension line should be there. If not, adjust the crop boundary a little farther. It doesn't take much. Once you have the dimension with the extensions, you can even adjust your crop back tighter without losing your extension lines.
You can also dimension the geometry before you crop the view.
This response may be waaayy too late and many having the issue may have found a solution. If you right-click near the arrow on the extension line that is showing select "display options" form the pop-up menu and then you can un-check "foreshorten". This solved my issue but I don't know how "foreshorten" was selected in the first place. Hope this helps!
David thanks,
Not too late!
This did it for me!
Just as another alternative solution, assuming it works in earlier versions than 2019 which i'm using, if you highlight the dimension and in the main menu hit the "default attribute" button as indicated below, that also fixes it ...
How about 1rRight clicking on the dimension and selecting "Show extension line" from context menu?
