version: ArcGIS 10 I am using a number of lines in certain polygon. As I apply offset value to the outline, spikes/kinks are produced as shown in the picture. Any solutions to remove the spikes and represent line as it originally is? Plus why is there a greater distance between the lines at places then others, indicated in blue and pink lines.
I believe this is an artefact of the cartographic line endings properties, joins and caps - Check out how the line caps are configured, and try different options out. You probably need bevelled joins and butt caps. Apologies for not having a screenshot in English, but I though it might help you nonetheless.
The ESRI page on Essential symbol and style vocabulary describes the behaviour of the different types of caps and joins.
