- What is an axis in MDT and what information does it contain?An axis is an entity that represents the ground plan layout of a linear work. It is composed of Critical Sections (VERTEX) that store…
- What methods exist for creating an alignment?MDT offers various ways to generate an alignment depending on the data source: Convert Polyline to Alignment: Transforms a polyline from…
- What is the difference between an "Alignment" and an "Axis"?Although they are often used as synonyms, in MDT alignments are the independent geometric primitives (straight lines, arcs, clothoids)…
- How can the elements of an already created alignment be edited?There are several editing tools: Edit Vertex: Allows you to modify the radius or parameters in a specific element. Adapt to Line: removes…
- What is "Alignments Dimension"?Alignments dimension is the process of labeling marks and texts following standardized criteria. It allows you to draw: Short and long…
- What is the Curvature Diagram?The curvature diagram is a graphical representation that shows the curvature of the axis (Radius / Curvature factor) along its…
- Is it possible to check if an alignment complies with Road Regulations?Yes, MDT has the Check Road Regulations command. This analyzes the geometric characteristics of the alignment (such as minimum radii or…
- What utilities are available to analyze the relationship between several alignments?Distances Between Alignments: Calculates the distance between equivalent kilometer points of two different alignments. Intersections of…
- Can alignments be exported to other formats?Yes, MDT allows you to export alignments to formats such as LandXML, convert files to specific formats compatible with other software, or…
- How are alignments integrated into a complete road project?Alignments are the basis of the Segment (file with .SEG extension). A segment links the horizontal alignment with its profile, grade…
- Semantic errors in the EJES.dcl dialog fileThis error can happend after a ZWCAD update, specifically from September 2026 onwards, on versions MDT25 or earlier. To fix it, copy the…
