“Plot Style tables are all well and good, and you get a big gold star if you’ve created your own. If you want something equally powerful, but a wee bit less technical, consider the Viewport Override columns in the Layer Properties Manager.
How to Assign a Layer Color By Viewport (Viewport Override)
- On the Layout tab, activate the viewport in which you want to edit the layer colors.
- In the Layer Properties Manager, select the layers to re- ceive the viewport override for the color property.
- In the VP Color column, click the color swatch of one of the selected layers, then make your selection for the viewport override color for the selected layer(s) in that viewport.
In addition to the VP Color column, you also have VP Line- type, VP Lineweight, and a couple others.
MEMO: To cancel the Override color setting,under the VP Color column, select the layers, right-click anywhere in the list, then click Remove Viewport Overrides for >Selected Layers >In Current Viewport Only. ”

Yesterdays meteorite impact in Russia left thousands wounded and a lot of damage to buildings. Here is some new information provided by NASA:
“New information provided by a worldwide network of sensors has allowed scientists to refine their estimates for the size of the object that entered that atmosphere and disintegrated in the skies over Chelyabinsk, Russia, at 7:20:26 p.m. PST, or 10:20:26 p.m. EST on Feb. 14 (3:20:26 UTC on Feb. 15).
The estimated size of the object, prior to entering Earth’s atmosphere, has been revised upward from 49 feet (15 meters) to 55 feet (17 meters), and its estimated mass has increased from 7,000 to 10,000 tons. Also, the estimate for energy released during the event has increased by 30 kilotons to nearly 500 kilotons of energy released. These new estimates were generated using new data that had been collected by five additional infrasound stations located around the world – the first recording of the event being in Alaska, over 6,500 kilometers away from Chelyabinsk. The infrasound data indicates that the event, from atmospheric entry to the meteor’s airborne disintegration took 32.5 seconds. The calculations using the infrasound data were performed by Peter Brown at the University of Western Ontario, Canada.
“We would expect an event of this magnitude to occur once every 100 years on average,” said Paul Chodas of NASA’s Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, Calif. “When you have a fireball of this size we would expect a large number of meteorites to reach the surface and in this case there were probably some large ones.”
The trajectory of the Russia meteor was significantly different than the trajectory of the asteroid 2012 DA14, which hours later made its flyby of Earth, making it a completely unrelated object. The Russia meteor is the largest reported since 1908, when a meteor hit Tunguska, Siberia.”
