About Toposolids
The Toposolid tool defines a topographical element using defined elevation points or imported data.
Create a Toposolid by Sketching
Create a toposolid by sketching a boundary and placing elevation points.
Video: Create a Toposolid
Create a toposolid by sketching a boundary and defining elevation points.
Create a Toposolid from Imported Data
Automatically generate a toposolid based on 3D contour data imported from DWG, DXF, DGN, or CSV points files.
Simplify Topography
Each point in a topography creates triangulated geometry, which adds to the computational overhead. When an element is created using a large number of points, you can simplify it to improve system performance. When the element is simplified, the accuracy and geometry of the contours may be affected depending on the specific conditions of the topography. After the element has been simplified, verify the contours and geometry. Add points for accuracy if needed.
Control Contour Display on Toposolids
Specify settings for contour line display, on toposolid family types.
Sub-divide a Toposolid
Define an area of a toposolid to offset from the original toposolid surface.
Sub-Division Instance Properties
Modify instance properties of a sub-division to change material, offset, and contour display.
Create a Graded Region
Grade areas of the topography, changing elevations at selected points, to develop the proposed site design.
Toposolid Instance Properties
Modify instance properties to change a toposolid's level, height offset, slope, and more.
Toposolid Type Properties
Modify type properties to change a toposolid structure, default thickness, function, and more.
