Fuzz factor????

[trilok2047]

When i use PEDIT command to convert lines into polyline, it asks for fuzz factor(numerical value)... what actually is a fuzz factor and how can i know the value of fuzz factor for different drawings?????/

The fuzz distance sets the search distance for endpoints to join. For example, if you set the distance to 2", AutoCAD will join endpoints that are 2" or closer.

The fuzz factor is just a tolerance, a distance in the current drawing units. When lines are joined together using PEDIT the end coordinates of each line are compared and if they are the same the lines are joined if they are not the same the lines are not joined. But because of the accuracy of the system if the endpoints have an extremely small difference in their coordinates (0.000000000001 for example) then they are considered not to be the same and are not joined together. If you enter a fuzz factor the lines will be joined if the difference in their end points vary by an amount up to the fuzz factor you entered.

 

We get drawings from one engineers office that doesn't use AutoCAD and each point in a survey is depicted by a dot in a small circle symbol and the lines joining the points starts and ends at the circles. Which means none of the lines intersect. We use PEDIT for multiple objects and enter a fuzzy very slightly more than the diameter of the circle and join all the lines together. Then explode all the previously created polylines to get our intersecting lines, we do that because PEDIT only creates 2D polylines and we need to work in 3D.

I call it the 'fudge factor', as previously described, it is sort of like insurance against imprecise work.

Much like the HALOGAP variable which determines how large a gap in geometry may be, before it raises a flag in the HATCH command.

[ReMark]

There shouldn't be a need to use a fuzz factor if one utilizes OSnaps in the construction of their drawing.

Just hit enter when prompted for the FUZZ FACTOR, which will apply the default value of 0.

If your join gets kicked back after doing that, then you can apply a fuzz factor.

thanks a lot to all of u ............
