![]() If you double–click with the mouse wheel, you will activate the Zoom Extents command. As long as the scroll wheel is pressed down, you can drag the mouse to change your view position without zooming or moving any objects. When you press down and click with the mouse wheel, the cursor will turn into a hand icon and the Pan command will temporarily be activated. You can also pan by clicking and dragging with the mouse wheel, using it as you would a mouse button. Point the cursor to where you would like to zoom and turn the mouse wheel to zoom in and out. Zooming and panning in AutoCAD can be done entirely with the mouse wheel. The issue is how you draw your perpendicular lines, they're not really perpendicular.Learn the basics of AutoCAD navigation to make your workflow easier. Surely you're not suggesting that map will be inaccurate. If a cartographer were to draw a map of the Mississippi River from its headwaters in Minnesota to the Delta in the Gulf of Mexico, the distance would be greater than 1200-miles. What would happen to the angles? Would the angles which were accurate before scaling be inaccurate after scaling?ĭon't use endpoint-to-endpoint to draw perpendicular, use Endpoint-to- Perpendicular Point (wherever that may be) using the Perpendicular Object Snap. What if someone were to SCALE the scale the lines 10,000X using 0,0 as the base point? Not only would the both line lengths increase 10,000X but the distances from the base point, 0,0 would increase too. It's a myth, some might even consider it a scam, so don't be fooled like those duped out of their savings on the 6 o'colck news.Īre you saying if two lines are drawn in inches and close to 0,0 the perpendicular angle is accurate? This argument about being too far away from 0,0 always makes me laugh. You're right, it doesn't have an effect on AutoCAD. I want to know what's wrong with the file though. This problem persists on Autocad 2019, 20. ![]() The parallel lines are no longer parallel and the perpendicular line is not perpendicular to either line. Select all 3 lines and rotate them from any base point. Draw a perpendicular line from endpoint to endpoint. Not only is this line not perpendicular, but it is also a different angle from the first perpendicular line above. Take it a step further. Draw a line -> first point shall be the midpoint of one of the parallel lines -> temporary snap PER to second parallel line (don't use the midpoint snap). ![]() The perpendicular line is not perpendicular to the parallel lines. Offset said line an inch to create 2 parallel lines. ![]()
