The number of nodes has driven me crazy and the contour ended up crashing my computer several times. Do I need to change something in the magic wand settings? I've tried fiddling around with it but nothing seems to change the outcome. Does it require an external add-on or scripting?<BR /><BR />I could just trace over the contour lines with poly or spline to dramatically reduce the number of nodes, but I want to be '100%' accurate, identical to that of the information provided by the land surveyor.<BR /><BR />If anyone had the same problem and knows how to solve it, please share your knowledge!</DIV> Wed, 31 Jan 2024 14:45:43 GMT https://community.graphisoft.com/t5/Documentation/Reducing-Nodes-when-using-magic-wand-for-contours-from-surveyor/m-p/223199#M62849 Anonymous 2024-01-31T14:45:43Z https://community.graphisoft.com/t5/Documentation/Reducing-Nodes-when-using-magic-wand-for-contours-from-surveyor/m-p/223200#M62850 Unfortunately the magic wand can not reduce the number of nodes in your surveyor's polyline.<BR /> It uses those nodes in the polyline as points in the new magic wanded line, and can only add extra nodes (or not) between those points - depending on the magic wand settings.<BR /> But the original nodes will be in the new magic wanded line no matter what settings you have.<BR /> <BR /> The only way to reduce them is for you to manually place a new polyline or spline by picking as many of the surveyors nodes as you need for the new line.<BR /> <BR /> Barry.
