Re: displaying contours takes a long time............

So I don't know if I'm the only user to have this problem but I think I pin-pointed the issue and wanted to share.


When I change the masking to "contour line only"  using the properties box it slows down displaying contours dramatically. Once changed back to "from label style" things went back to normal speed.


When I changed the style to "contour line only" (instead of doing it through the properties box) it works fine. I accessed the override by going to annotation>add labels>surface>[box next to label type] and setting the contour label default override to contour line only.


Thanks everyone for the help; I'm sure it seems like an easy fix for most but this frustrated the hell out of me.

This actually does not work the same.


When you switch all the currently drawn labels to mask "from label style," you are setting them all to mask based on the actual label style which will either a) mask EVERYTHING behind it (including hatches - which can be ugly) if the label style has background mask set to "True," or b) mask NOTHING if the label style has background mask set to "false."


When you change the feature setting to mask "contour line only" the way that you mentioned second (which can also be done via the settings tab of the Toolspace by right clicking "Surface" and selecting "Edit Feature Settings") it will only apply this to future labels that you add. It will not change the labels which you've already changed to mask "from label style" through the properties box. Those labels will still only mask from their label style as mentioned above.


There is some kind of conflict where masking the contour line only is slowing down the processing of the display of the contour lines, so unless all your labels are set to mask "from label style" the drawing remains slow when displaying contours.


To verify this for yourself, add a solid hatch below the contour labels and set the labels to mask "from label style" and you will see that you can only make them mask everything or nothing. Quite annoying in my opinion.


Hopefully AutoCAD addresses this soon, as I hate having boxes of emptiness around my contour labels when there is a solid gray hatch behind them for paving.

Does anyone know if this has been fixed? or if there is a work around?  Drawing was extremely slow then I saw this post and change my labels back to the style.  Really would like to use the “contour line” label so that it won’t look like holes in my aerial …..


I’m using C3D 2012
