More obvious is to use the subtraction with upwards or downwards extrusion (which I think should just be called "Subtract Up" and "Subtract Down" - that dialog is way too big). You will notice that SEOs create the intersection lines between elements in any operation and these are visible regardless of the layer settings.<BR /> <BR /> As Ben points out the results are only visible in 3D. And, per Stuart, do not delete the operators or the effect disappears with them.

I'm preparing a series of lectures and it'd be really good to show this to the students. <BR /> <BR /> For example I create two slabs (or a slab and a wall) to try and subtract one from the other. Select the target element, select the operator element, set to subtract. Click on execute and.... nothing. I've followed the help files a number of times and it would appear to be quite simple really. It's just not happening though <IMG src="https://community.graphisoft.com/legacyfs/online/emojis/icon_sad.gif" style="display : inline;" /> <BR /> <BR /> Any ideas?<BR /> <BR /> ArchiCAD 9 EDU on Mac OS 10.4.6</R></DIV> Thu, 25 May 2023 16:00:23 GMT https://community.graphisoft.com/t5/Modeling/Solid-element-operations-help-me-make-them-work/m-p/57754#M29308 Anonymous 2023-05-25T16:00:23Z https://community.graphisoft.com/t5/Modeling/Solid-element-operations-help-me-make-them-work/m-p/57755#M29309 <BLOCKQUOTE>theginjaninja wrote:<BR />Any ideas?</BLOCKQUOTE> are you doing it from the 3D window?<BR /> <BR /> ~/archiben Sun, 09 Apr 2006 23:05:19 GMT https://community.graphisoft.com/t5/Modeling/Solid-element-operations-help-me-make-them-work/m-p/57755#M29309 __archiben 2006-04-09T23:05:19Z https://community.graphisoft.com/t5/Modeling/Solid-element-operations-help-me-make-them-work/m-p/57756#M29310 And deselect the target elements before selecting the operators (or vice versa), and put the operator elements on a layer which is turned off (do NOT delete them).
