-TINEDIT command

Edits a TIN surface via Command line.

BricsCAD Pro; BricsCAD Mechanical; BricsCAD BIM

Description

Allows you to edit existing TIN Surfaces. Editing options affect the way TIN edges connect TIN points to form triangles. You can also delete existing TIN points and edges or add new ones or change the position and elevation of existing TIN points.

Any TIN Surface editing operation can be modified in the Civil Explorer panel after the execution. It is also possible to change the chronological order of editing operations.

Options within the command

Add Points
Adds new points to the existing TIN Surface.
Note: These entities are added to the TIN Surface as drawing objects definitions.
Select points or linear entities
Selects points or linear entities to add to the TIN surface.
Pick points
Allows you to specify the location of the TIN point.
Enter elevation
Allows you to enter the elevation of the TIN point.
Add Point Groups
Adds Civil points from a specified Point Groups to the existing TIN Surface.
Note: By default, Civil points are placed in the “_All points” Point Group. Use the CIVILPOINTGROUP command to create a new Point Group.
Enter Point Groups names
Allows you to enter the Point Groups names, separated by comma.
Add Breaklines
Adds selected linear CAD objects to the TIN Surface as breaklines.
Select breakline type
Allows you to choose the breakline type.
Standard
Adds breaklines to the TIN Surface, re-builds the TIN Surface so that triangles follow the breaklines edges and elevations.
Projected
Projects breaklines to the TIN Surface and creates new triangles, without modifying TIN Surface elevations.
seTtings
Allows you to choose the settings for the Standard breakline type only.
Use weeding factors?
Toggles the use of the weeding factor.
Enter weeding distance
Sets the weeding distance.
Enter weeding angle
Sets the weeding angle.
Note: Existing breakline vertices are not used to create a TIN Surface, if the distance and angle between them is less than the specified weeding parameters.
Use supplementing factors?
Toggles the use of the supplementing factors.
Enter supplementing distance
Sets the supplementing distance.
Note: Additional vertices are added to breakline, if the distance between vertices on the breakline is greater than the specified supplementing distance.
Add bOundaries
Adds selected linear CAD objects to the TIN Surface as boundaries.
Select boundary type
Allows you to choose the boundary type.
Show
Displays triangles inside the boundary polygon.
Hide
Hides triangles inside the boundary polygon.
Outer
Defines the outer boundary of the TIN Surface. All the triangles outside the boundary are hidden.
Trim triangle lines
Yes
Trims the triangles (TIN edges) that intersect the boundary to follow the boundary polygon.
No
Deletes all triangles that intersect the boundary polygon. This is the default option.
Clip
Clips an existing TIN Surface in the drawing with a selected polygon as the clipping boundary for the surface.

Does not change the TIN Surface boundary but affects all elements (TIN operations) added to the TIN Surface after the Clip boundary. Only elements located inside the Clip boundary affect triangulation.

Remove Points
Removes points/vertices of triangles from the TIN Surface.
Multiple
Allows you to remove multiple TIN points at once.
Swap Edge
Swaps the selected TIN edges.
Note: Edges cannot be swapped in following cases:
  • when the TIN edges lie on the breaklines.
  • when the TIN edges are created with the Add line definition.
  • when the TIN edge belongs to two adjacent triangles that form a concave envelope.
Point Location
Modifies the location of a single or multiple TIN points in one step.
Multiple
Requires a polygonal selection of multiple TIN points and specifying a base point and second point for moving the TIN points.
Point Elevation
Modifies the elevation of a single or multiple TIN points in one step.
Multiple
Requires a polygonal selection of multiple TIN points. Then determine the new absolute elevation or delta elevation (elevation difference).
Add Line
Adds new TIN Edge between existing TIN points.
Delete Line
Deletes TIN Edges inside the specified selection area.
Note: The edges inside the selected area are colored red.
Remove Outer Edges
Removes triangles on the outer boundary of the TIN Surface, that have:
  • greater edge length.
  • shorter edge length.
  • greater angle than specified.
Note: You can specify which of these criteria is considered when removing the outer edges.

This method begins removing triangles from the outer boundary towards the inner part of the TIN Surface. It stops removing triangles, when the last outer triangle meets the specified criteria. That means that this method does not remove inside triangles.

Use maximum triangle length
Toggles the use of the maximum triangle length.
Maximum triangle length
Allows you to specify the maximum triangle length.
Use minimum triangle length
Toggles the use of the minimum triangle length.
Minimum triangle length
Allows you to specify the minimum triangle length.
Use maximum angle
Toggles the use of the maximum angle between adjacent TIN lines.
Maximum angle between adjacent TIN lines
Allows you to specify the maximum angle between adjacent TIN lines.
Minimize Flat Areas
Finds flat triangles and then swaps the adjacent TIN edges of those triangles so that their slope is non-zero.

This method is most useful when the TIN Surface is created from Contours. It starts at the concave side of the contours and swaps the edge of the first triangle so that its slope becomes non-zero. The process continues until the method still ensure that there are no flat triangles by swapping their edges.

Note: Minimize flat areas method swipes only the TIN edges that do not lie on breaklines.
Remove Elevations
Removes TIN points below/above the specified elevation and displays the number of points removed.
Remove points below elevation
Toggles the option to remove TIN points below a specified elevation.
Remove points with elevation less than
Sets the elevation below which TIN points are removed.
Remove points above elevation
Toggles the option to remove TIN points above a specified elevation.
Remove points with elevation greater than
Sets the elevation above which TIN points are removed.
SMoothing
Allows you to smooth a TIN surface by adding additional points.
Enter grid X spacing
Allows you to set the grid X spacing value.
Enter grid Y spacing
Allows you to set the grid Y spacing value.
Enter grid angle
Sets the grid angle value. You can also define it by picking the angle in the drawing area.
Entire TIN surface
Yes
Selects the entire TIN surface.
Pick polygon
Allows you to define the TIN surface area for smoothing by picking a polygonal selection window.
