The images will be stored in your tool palette folder. Third, drag and drop the line onto the tool palette.
So, to let AutoCAD do the work, first, create a block of the line: Brian Tait, from Cheniere, reminded me that we could let AutoCAD do all that work for us. If you see the palettes that are included with AutoCAD installation, you will see a collection of AutoCAD blocks, hatches, and other tools. Snipped from help file: Tool palettes are used to manage blocks, hatches, and other custom tools. So, in the last post we did a bunch of extra work making an image for a tool palette. Later, we will use palette to access the reusable contents when we draw. Drag and drop items directly from open tool. Go into the palette, by clicking on its icon, to add/modify content. This opens a dialog box where you fill in the name, description, keywords, and publisher information.
