How to show arc distance partially in Autocad

When you take arc distance from Autocad, it will usually show full arc length. Then how to take arc length in between two points where you specify? We have used Autocad 2016 for demonstration. First select arc tool from ribbon or drop down menu,

How to divide a curve or arc in to equal segments in Autocad 2016 – tutorial (divide tool)

The “measure” tool will divide the arc in to specified length point, so there can be an odd value at the last segment. For example if the arc length is 45 m and specified length is 10 m, only the last segment will be 5m instead of 10 m.
The “divide” tool will divide the arc in to specified number of segment of equal length of points, so there won’t be any odd value at the last. For example if the arc length is 45 m and specified number of segment is 10, each segment will be (45/10) 4.5m interval.

How to divide a curve or arc in to specified segments in Autocad tutorial

How can you divide a curve or object into equally sized segments?You would have tried to find a solution for days! It doesn’t actually have to be a ‘physical’ devision. But it would be good to know a solution for both: dividing eg. a curve into equally sized segments, ie. creating vertices Read More

Temporary Adjustments of Total station

November 20, 2015November 19, 2017 ART OF SURVEYING 1 Comment

Temporary Adjustments of Total station

Adjustments which required to be made at every instrument station before making any observation. It can be done through following three procedures,

1.Centering the Total station over the station.
2.Levelling the Total station.
3.Elimination of parallax.

1.Centering the Total station over the station.

This include the Centering of the Total station over the ground mark and also approximate levelling with the help of Tripod legs. While centering, it is necessary to ensure the approximate levelness; otherwise the centering will be disturbed when subsequent Levelling of the instrument is done. It can be done either using a plum-bob or laser plummet.

2. Levelling the Total station

Accurate Levelling is done with the help of plate levels using levelling screws.Here the Vertical axis (plumb line)of the Total station is made truly vertical.

Definition of Surveying

Surveying is a art of making measurements of the relative positions of natural and man-made features on the earth’s surface, and the presentation of this information either graphically or numerically.
