I have 1700 cross sections lines in a shapefile that are too short and I need to extend all of them about 100-200ft. Ask Question Asked 5 days ago. How to extend multiple lines at once ArcMap.

I draw another line of specific length, and then set the angle to 30.(Remain in the same Extend command.) Pick the two ARCs near P1 & P2 to extend these ends of the ARCs to the boundary object and press to signal AutoCAD that you have selected all objects to extend. Lines and tangent curvesSelect AutoCAD AutoCAD LT Autodesk Inventor CADKEY CATIA Mechanical Desktop Other. If you have a civil/survey program or add-on, such as Land Desktop, SurvCADD, Eagle Point, etc., then there are built-in tools for entering lines and curves. These techniques apply to basic CAD programs such as AutoCAD, IntelliCAD, etc.

Linear dimensions create distance measurements between two points in the.For each line segment, a bearing and distance is given.Start the. Let's start in the lower left (or most southwesterly) corner and work clockwise for this example.include dimension text, dimension lines, extension lines, and arrowheads. Start with a line segment if there is one. Below is an example of what you might have. Let's work our way around it.

_LINE command because you need to draw a curve next. Then at the next prompt enter stay in the line command and draw the next segment. If you have XY or Northing and Easting coordinates, you can enter them, otherwise just pick any point in the drawing.

The image below is how it should look now (the green line is the new one).Now rotate this line, using the opposite endpoint as the radius point. The opposite endpoint is the center point for the next curve. _LENGTHEN command to set the exact length. Make this line the same length as the radius of the curve.

We need to do the same as above to find the center point, except rather than draw a perpendicular line, we need to draw a radial line from the previous curve.In this case we already have the green line in place, so extend it out past the last curve a bit. If the second curve goes in the same direction, it's called a compound curve, if the second curve goes in the opposite direction, it's called a reverse curve.Notice that this curve is to the left, not the right, so this is a reverse curve. This curve is also tangent, but in this case the previous entity is a curve.

The other end is the center point for the next curve.Now rotate this line the amount of the delta, just like before. _LENGTHEN command to make this line 500 foot long (the radius of this curve). It should look like this now.Now use the.

However, take a look at the figure. Chord Bearing and Chord DistanceThe Chord Bearing is the bearing from the start point of the curve to the end point of the curve.Going back to the first curve in the figure above, we can see that the Chord Bearing is N30D57'08'W. You can use either the Chord Bearing and Chord Distance or you can use the Radial Bearing. This is the case for non-tangent curves in the middle of a figure or if you want to start your figure with a curve. _LINE command and pick the endpoint of the last arc, then enter Non-Tangent curvesThe orientation of tangent curves is determined by the previous entity, but for non-tangent curves you need to know how the curve is oriented. Now it should look like the picture below (the radius point is not shown since it is so far away).Now you have your three points from which you can construct the arc.The last line segment is constructed just like the first two.

The string you will use is you have this line, you can draw the curve. The actual Chord Bearing is S30D57'08'E.So now, draw a line that represents this Chord Bearing, using the same syntax as above. So just replace the NE with SW. Depending on the direction you are traversing a figure, you may need to reverse bearings by 180 degrees.Remember, the Chord Bearing is the bearing from the start point to the end point so in this case, the Chord Bearing is in the SE direction, not NE. This is something else you may run into.

In our original example, the radial bearing is not given but it is S28d45'21W. This line will run from the last endpoint to the center point of the next curve. Radial BearingThe Radial Bearing is the bearing from the start point of the curve to the radius point of the curve.If you are given a radial bearing, you can use this to lay out a non-tangent curve also. If the curve is opposite of what you expect, select the start and end points in the opposite order.Use this same technique for non-tangent curves.

However, if entering this type of data is a frequent occurance, you may consider upgrading to a program that includes faster methods for this type of data entry. SummaryUsing most CAD programs including vanilla AutoCAD, you can enter survey data from a drawing or deed without needing any special tools or add-ons. From this point on, you can follow the same steps as above when you constructed the perpendicular line and rotated it.
