Automatic polylines correction

Automatic polylines correction

This command is designed to correct polylines mainly produced as a result of automatic vectorization or tracing. Depending on the settings, it can perform merging, removing or the combining of polylines. Other types of objects will also be automatically converted into polylines.
This command can be performed only while vector objects are selected.
Set up the command options in Polyline Correction Options dialog. To launch this dialog choose Polyline Correction Options from the Correct menu or click the button on the VectorCorrection toolbar.

Remove Small Segments

Consolidates polyline nodes connected with a segment which is smaller or equal to the parameter value shown in Minimal Size to remove. A larger value causes the more distant nodes to consolidate into one. This type of correction allows elimination of overlapped and surplus segments. To achieve the best result the Minimal Size need to be correctly set to the remove value. This can be measured this directly from the document.

Remove Small Objects

Removes Objects smaller than the set value.
This type of correction can be used for removal of small vector trash that has appeared as a result of automatic vectorization

Kill Internal Objects

If this checkbox is set, then during the correction the objects located inside the uncrossed closed polylines will be deleted.

Merge Nearest Polylines

Merges the nearest polylines into one by adding new segments between the endpoints of polylines. Minimal Distance to merge can be set up using an appropriate parameter.

Snap Nearest Polylines

Snaps polylines located near each other. The size and location of one line changes when it is connected to another. This is different to the Combine Closest Polygons operation, where the ‘combination’ does not appear as the two become one.

Combine Closest Polygons

Combines closed polylines (polygons), located closer to each other than the maximum size parameter value, into one object.

Make Orthogonal Segment

This changes a polyline segment to be orthogonal to another segment.
Set the angle value directly in the ‘base angle’ parameter or allow the application to calculate the angle automatically.

To start polylines automatically corrections choose Polylines Autocorrect from the Correct menu or click the button on the VectorCorrection toolbar.
To perform polylines corrections do the following:
1. Open the file with the vector objects needing to be corrected.
2. Estimate the correction and activate the required algorithms. Almost all of them require the setting up of the parameters, so do not forget to measure the values in the document using designated tools (ruler button). Setting up the parameters can be performed from the Polyline Correction Options dialog box.
3. Select the vector objects that need to be corrected.
4. Run the Polylines Autocorrect command.
