I have a drawing that has multiple View ports, I used Multiblocks and AEC Elevations / Sections. When I plot the DWG the same Viewport will always plot with a "0" / light line thickness. If I turn on the LWT button (at the bottom of the Acad window) it will display the Line thicnkess fine but will still plot "lightly" I'm baffled the object is a Multiview block in a 3D South east view (useing a Named View). All the other Viewports plot fine. Now I know it's not the Plotter. I Started a New DWG, I imported the Named view, I even put a couple of 3D solids and 2D objects in the new Dwg and then I did a copy-paste with a base point of the Mutli view block and put it in the New drawing, Created few new view ports in a layout tab and displayed all my new objects in one Viewport and made a new Viewport for the Copied Mutli view block, activated the named view and it plotted - Perfect, the Line thickess were exactly what I was supposed be getting from the other Dwg. I tried few differn't times to fix the Viewport problem in the 1st drawing I created: I made a new Named View, New Viewport, I even checked the Style Manager and the View port is set to "System Default" in both the old and New drawing (changing the View "Style" had no effect) - Yet the New Dwg is plotting it fine. I didn't put this post this in the "Plotting Newsgroup" because the problem isn't with a plotter but with a Drawing and a Viewport. Has any one seen this before? TIA
