Command line: GT_DELDUP 
This command deletes duplicate entities from an AutoCAD drawing. This is a very powerful tool to quickly clean AutoCAD drawings that have redundant duplicate data. Entities which are geometric duplicates, either exact or within a specified tolerance can be identified and removed. Duplicate check can be performed by taking into consideration their extended entity data or layer criteria as well.

Command line: GT_NULLTEXT 
Often, various aborted DIMENSION and TEXT commands result in the formation of null text objects which cannot be seen but are present in the drawing and affect operations like ZOOM EXTENTS. They also increase the drawing size unnecessarily. The GT_NULLTEXT command gets rid of all such "ghost" text objects.

Command line: GT_NODELINESNAP



The GT_NODELINESNAP command replaces the earlier MAGNET command is used to perform automatic drawing cleanup of linear segments and point [node] objects. This command fixes undershoot and overshoot errors in lineworks, allows for snapping of points in lines, polylines, arcs etc to nearby linear or point features. Point work cleanup also can be performed and by this technique, points can be snapped to other points or lines in the vicinity. Typically, a map data resulting from a manual digitization or raw GPS or surveyed data will have many of these kinds of errors, which can be easily fixed with the MAGNET command.

GT_NODELINESNAP automatically "looks" at the nodes of linear features and snaps them to nearby linear or point features.

Linear features include AutoCAD lines, polylines, arcs or spline objects.
Point or Node objects include AutoCAD Point, Insert [ Blocks] and Shape objects.

The command works equally well with both 2D and 3D objects. In case of a 3D object like a 3D polyline vertex, the snapping can be performed in either X, Y directions retaining existing elevation (Z) value or it can inherit the elevation (Z) from the neighboring object. Applying two tolerances [NEArest and ENDpoint] around the ends of the linear features searches the neighboring object. For node objects, the distance to search around the point is specified by the NODe tolerance.

A dialog box pops up and displays the parameters to set for this operation.

Snap Type: Specify the type of snapping to be applied.

Line2Line: Snaps linear objects to other linear objects only
Line2Node: Snaps linear objects to other point objects only
Node2Line: Snaps point objects to other point objects only
Node2Node: Snaps point objects to other point objects only

Snap criteria for Line2Line / Line2Node: Additional snap criteria for Line2Line and Line2Node snap modes determine which vertices to apply the snap.

All vertices: Applies snap to all vertices of selected lines, polylines, splines etc.
First and Last only: Applies snap to only the first and last vertex only. Useful for linework cleanup where only end snapping is required.

Snap Mode: Defines another mode of snap operation

XY Only: Snapping is done only in the X and Y directions [two-dimensional direction] only. The source Z value is retained and transferred to the target point.

XYZ Only: Snapping is done in the X, Y and Z directions. The new elevation Z value is obtained from the target point.

Other parameters: Specify other snap parameters

END search tolerance: This is the distance to search around the vertices for the ENDs of an AutoCAD object segment as returned by the Osnap Endpoint mode. This tolerance is measured horizontally. Applies to Line2Line and Node2Line Snap Modes.

NEArest search tolerance: This is the distance to search around the ENDs of an AutoCAD object segment for the NEArest AutoCAD object segment as returned by the Osnap Nearest mode. This tolerance is measured horizontally. Applies to Line2Line and Node2Line Snap Modes.

NODe search tolerance: This is the distance to search around the point for the existence of a NODe or an INSert object. This tolerance is measured horizontally. Applies to Line2Node and Node2Node Snap Modes. This snap mode snaps only to points, inserts and shape objects. For points, the NODe Osnap mode is applied and for Inserts and Shapes, the INSert Osnap mode is applied. 

Z search tolerance: Source and target points whose elevation difference is lesser than this amount will only be snapped. This tolerance is provided to prevent a very high elevation difference from being snapped.

Snap to objects within current selection only: Checking this option causes the snap to be successful ONLY if the target point falls on an object which belongs to the initial selection. Use this option when you want to snap within the selection only. For example, you may have a network or minor roads and major roads and you want only the major roads to snap to themselves. You can achieve this by checking this option and selecting only the major roads for you snap operation.

Command Operation: The GT_NODELINESNAP command works under two main modes of operation - Linear Snap and Node Snap.
In Linear Snap, source objects snap on to linear objects like lines, polylines, arcs, splines etc. The source objects themselves can be linear (Line2Line mode) or nodes (Node2Line mode).

In Node snap, objects snap on to node objects like points, blocks and shapes. The source objects can be linear (Line2Node mode) or nodes (Node2Node mode).

In Linear Snap, two tolerances are applied in the following order - first a NEArest tolerance is applied to determine the nearest point on a vicinity object. If no NEArest point is found within the specified NEArest tolerance, an ENDpoint is searched for on a vicinity object. If it succeeds, the point is snapped and updated. If it succeeds, the point is snapped and updated. If no ENDpoint is found within the specified ENDpoint tolerance, no snapping takes place. If the snap mode is XY only, the point is moved horizontally and the original elevation is maintained. If the snap mode is XYZ, the point acquires the target Z value if the elevation difference is within the Z tolerance. Otherwise, no snapping takes place.

In Node Snap, only one tolerance is used - NODe tolerance. This is applied around the point in consideration and it looks for a nearby point, block or shape insertion point. If one is found within the NODe tolerance, the snap is successful. As with LineSnap, the Z tolerance check is applied here also.

Command line: GT_INTEX 

The GT_INTEX command is useful in processing a network of intersecting polylines. Using this command, intersecting polylines can be broken at their intersections or just have a vertex added at the intersecting points. Further, two selection sets  can be established - a source selection set and a target selection set and one can be made to operate upon the other. This provides a means to filter objects used for processing.

Important note: The GT_INTEX command works only with polyline objects. These can be either light-weight or heavy- weight polylines and they can be 2d or 3d polylines. They must contain only linear segments and must not be splined, fitted or contain arc segments. If you have source objects that intersect with target objects that are 3d polylines, make sure that your source objects are defined as 3d polylines if you want the intersecting points to acquire correct interpolated 3d elevations at the intersecting points.

The following commands in GeoTools may be useful in preparing correct data for use by the GT_INTEX command. GT_CH3D2D,  GT_CH2D3D,  GT_PLARC2PL,  GT_PL_STAT,  GT_SET_Z_PL.

Object Break Options: Specify the options that control  how source and target polyline objects should be broken at their intersection points.

Source Objects Only: Breaks only source polyline objects at their intersection with target polyline objects
Target (crossing) Objects Only: Breaks only target polyline objects at their intersection with source polyline objects
Both Source and Target Objects: Breaks both source and target polyline objects at their intersection with each other
None: No breaking is done. Only vertices are added according to the settings in Vertex Add Options.

Vertex Add Options: Specify the options that control how new vertices should be added to the source and target polyline objects.

Source Objects Only: Adds new vertices only to source polyline objects where they intersect with target polyline objects.
Target (crossing) Objects Only: Adds new vertices only to target polyline objects where they intersect with source polyline objects.
Both Source and Target Objects: Adds new vertices to both source and target polyline objects where they intersect with each other.
None: No vertices are added either to source or target polyline objects.

Source Objects: Select this button to bring up the selection set builder dialog box and select source polyline objects

Target Objects: Select this button to bring up the selection set builder dialog box and select target polyline objects

Target Selection conditions: Specify the method of defining target objects. Target objects are those which are operated upon by source objects.

Same as source objects: Checking this option causes the source object selection to be the same as target object selection. This means that intersections will be checked within one single selection set [ source selection ] itself. Any objects that cross the source objects and which is not in the source selection set will be ignored.

Select manually: Allows to manually specify the target selection set by screen pick. Source objects will be checked for intersections only within this selection set.

      Menu : GeoTools Bereinigung Tools Build common edges along closed adjacent polygons
Command line: GT_EDGEBUILDER

The GT_EDGEBUILDER command is a tool useful for building edges along adjacent, closed polylines. A typical scenario in GIS data preparation or modeling involves being able to create intersection-to-intersection edges from a network of closed polygons lying adjacent to each other. While many GIS applications create a network of closed polygons, very few easy and direct tools or procedures are available to create the common edges between polygons as unique, open polylines. The GT_EDGEBUILDER command was born in an attempt to fulfil this need in an easy way.

The program works on a selection of polygon boundaries and builds the unique edges between them. Like in every GeoTools command, it is best to start with as clean and accurate data as possible. BEFORE you start this command, it is essential that all duplicate segments from the selection are removed and cleaned using the GT_DISTANGWEED command.

Search Window Size around each vertex: Specify the value for search window around each vertex.

Command line: GT_JUNCTION
The GT_JUNCTION command creates points at every junction node. A junction is defined as a point where at least three or more segments branch out in as many different directions. So if you have a network of lines (or polylines) representing a road, parcels boundaries or any similar  linear/polygon feature, this command helps to identify every junction by creating a point object at that location. 

Please be aware that this command is somewhat similar (and different) from the GT_INTERSECT command, which creates a point at every segmental intersection, while the GT_JUNCTION command creates points at every junction or node where there is an explicit vertex or end point or ARC or LINE. In other words the GT_JUNCTION command does not identify segmental intersection where there is no vertex present) instead, it locates nodes where there are three or more segments originating and marks points on them.

      Menu : GeoTools Drawing cleanup Remove all unreferenced scales
Command line : GT_SCALECLEAN
The GT_SCALECLEAN command removes all un-referenced scales): There is a bug in AutoCAD which causes the SCAELLISTEDIT command to keep displaying all scales from any external reference that was once attached to the current drawing, even after they are detached and gone. The GT_SCALECLEAN command helps to get rid of all these un-referenced scales by removing the entires from the AutoCAD dictionary.
