Hi, How does Autocad handle pixel type plans (bitmap, tiff, jpg etc) for bringing in, to then be traced over with the polyline tools etc. Q1) Has it the ability to import a plan and place it on a layer to then be locked and traced over. Q2) If one has a plan of the objects front, another of its top view, another of the end view, how does one arrange these, different viewports perhaps ? Q3) Can it handle more than one plan, and control the stacking order, so if you want to see plan B on top of plan A, is that possible ? Q4) Is there a construction grid and is it visible still after a plan is brought in ? Is it necessary to make the plan translucent to see it ? Q5) Is there a size limit on the plan pixel width and height due to OpenGL or similar. What is the biggest size that can be brought in ? Q6) Can visibility be turned on or off ? Q7) Can greyscale plans be coloured and made translucent so as to register them together and compare content ? Q8) Can colour rgb plans be brought in and what are the limits, as these can have large file sizes. Is the limit autocad or the pc ? Q9) Does autocad allow adjusting of such plans for fit to the work drawn so far, scaling disproportionally as well as proportionally, rotation, distortion etc. Cheers Steve
