SUMAC

Sumac is a software that supports modeling surface terrain, creating contour lines, creating a plan, calculating the ground level according to the practical calculations of Vietnamese engineers.

In the field of design consultancy, construction planning and transportation . the help of computers with calculation software is becoming more and more popular. The construction of a program of calculating, modeling the terrain, creating contour lines and especially calculating the volume of earthwork in construction and transportation is extremely necessary. Stemming from that demand, the Center of Construction Software - under the Information Technology and Construction Consultancy Joint Stock Company (CIC) has completed the construction of Sumac software.

Sumac has an easy-to-use graphical interface (this graphical system is similar to AutoCAD), capable of accurately modeling the terrain surface, creating contour lines, and creating graphs by using grid interpolation method. and create terrain. Calculation results are fully shown on the drawings (surface terrain, contour lines, plots, calculation results of leveling in each cell and the total volume of earthwork in each row and column on the grid system. square). The resulting drawing can be exported as AutoCAD format (* .DWG; * .DXF).

The main feature of Sumac

1. Ability to enter terrain data:

• Enter data from the meter.
• Enter terrain data directly on the graphic screen.
• Import topographic data from AutoCAD format drawings (* .dwg, * .dxf)
• Read data from external data file as text.
• The program also has the ability to edit terrain data on the graphical screen .

2. Ability to model the surface:

Sumac can model the terrain surface before and after leveling as a 3D surface.

Or describe the terrain as a triangular grid.

3. The ability to create contour lines and plan:

Sumac creates contour lines from the grid, the altitude between the contour lines, the color, the frequency of the contour lines can all be changed by the user.

Each contour line is a seamless object on the drawing (in most other software of the same feature, the contour lines are discrete making it difficult to manage the contour objects of the user. )

4. Ability to create terrain sections:

Sumac creates terrain profiles according to each user-specified profile, pile steps, font height, and section names can be changed.

5. Help to build design contour lines:

Design engineers can declare a number of elevation control points, from these elevation control points, the program will build the design contour.

6. Ability to calculate Foundation Levels:

Sumac calculates San San according to the types of calculations commonly found in Vietnamese engineers:

- Calculation of San San is based on the control points of the design elevation: the user must enter the terrain at the end of the period enough to interpolate the elevation of the meshes to calculate the volume of earthwork. This type of calculation usually applies to the volume calculation after the land is poured on a given plot of land - in this case, the user has all the measurement data of the pre-forming profile after the landfill.

- Calculation of San Foundation based on design plane. This type of calculation is often used in calculating the leveling of a plot of land in construction.

- Calculation of San San is based on the design contour lines: the user will draw the contours on the drawing himself and declare the height of these contour lines or declare some high control points, the program will outline the design contour lines.

- Calculating the workload at the taluy of the sides of the land

7. Output of calculation results:

All calculation results will be exported to the graphic screen, each type of drawing object is arranged in separate layers. Calculation results on drawings can be customized to display.

The results of leveling calculation are recorded on each plot on the drawing and totaled in each row and column of the grid system. Calculation results are capable of rendering AutoCAD drawings (* .dwg).

8. Export the calculation results to an Excel spreadsheet:

The results of the leveling calculation are also exported to the summary of the volume as an Excel table.
