- What is a surface or triangulation in MDT?Obtaining the Digital Terrain Model (MDT) requires a prior process called triangulation. During this process, the surface is tessellated…
- How do you create a surface in MDT?The command Surfaces > Create Surface is used. The program allows simultaneous triangulation of various elements: Topographic Points: All…
- When creating a surface, the error "3 or more vertices are required" appearsWhen creating a surface, this error may appear if the program does not find elements to triangulate. There are several possibilities: If…
- What is the importance of 3D Break Lines?They are essential for the model to be accurate, as they define the terrain by marking slope changes such as thalwegs, tops or toes of…
- What tools are available to create 3D Break Lines manually or with assistance?The program offers multiple methods to facilitate drawing: Nearest Point: Allows you to draw by designating approximate positions, and MDT…
- How is the creation of 3D Break Lines automated using Codes?MDT allows you to DRAW lines automatically from the Codes Database (BDC), by executing the DRAW from Codes command. The program processes…
- How are surfaces represented in the drawing?There are several representation modes, depending on the need: Lines: Draws the edges of the triangles. Draw Cross Sections: Useful for…
- How can a surface be created from contour lines?To create a surface from contour lines in MDT, you must use the Surfaces > CREATE SURFACE command. This procedure consists of discretizing…
- Can surfaces be generated from LAS/LAZ files?Yes, it is possible to generate surfaces directly from LiDAR laser files in LAS and LAZ formats. MDT 25 has specific tools to process this…
- How can surfaces created by other applications be converted?To convert surfaces that have been drawn in the CAD by other applications or modified manually, MDT offers several tools depending on the…
- What is the "Convert Drawing" and why is it necessary?It is the Digital Terrain Model that the program takes as the default reference for curve commands, obtaining longitudinal and…
- Can a surface be edited once created?Yes, the Surfaces menu offers multiple interactive editing TOOLS. The most common are: Fix lines: Allows you to Distances the orientation…
- How can you prevent triangulation in an area, such as a building?To prevent triangulation in a specific area, such as a building, MDT primarily offers the use of Islands. An island is defined as an area…
- What rendering options are available to view a surface?When creating a surface, setting a surface as current or drawing it, you can choose from: None: it is not represented. Quick View…
- Can you work with multiple surfaces in the same drawing?Yes, in MDT 25 it is perfectly possible to work with multiple surfaces within the same drawing. To manage this efficiently, the program…
- How can platforms be created and their earthworks calculated?MDT offers specific tools to modify the current surface by creating platforms, allowing automatic calculation of the necessary cut and…
- What is the "Displaced Parallel" tool?Displaced Parallel is a utility for creating break lines parallel to existing ones (such as the other edge of a road or a wall) by…
- How are errors in 3D Break Lines verified?Using the Verify Break Lines command, MDT detects possible failures that distort the model, such as: Crossings between 3D Break Lines…
- Can 3D Break Lines be added to a surface that has already been created?Yes, it is possible using the Incorporate Polylines into Surface command. The user can choose whether the lines should assume the…
- What is Thickness in code?Thickness in code allows including one surface within another (the Convert Drawing). The process is equivalent to creating an island in…
- How is the volume between two surfaces calculated?There are two main methods: Mesh/Surface Difference: Compares two files (meshes or surfaces) by overlaying them. The volume of each cell…
- What external formats can be imported as surfaces?It is possible to import surfaces created with other programs using several commands: Create Surface, supporting formats such as Geotiff…
