Issue:
Civil 3D used to bring point clouds files such as LAS, TXT, etc. directly into drawing in 2017. Now it requires use of ReCAP? Is .LAS format supported in Civil 3D anymore?Causes:
This is as designed. Previous to Civil 3D 2018, it was possible to import .LAS point clouds directly through Civil 3D using the legacy point cloud utility. The legacy point cloud utility does not support newer versions of LAS such as 1.4 so Civil 3D no longer use the legacy point cloud tools.Import Dwf Into Autocad
Solution:
Use ReCap to convert the LAS, ASCII, etc. files into a format that can be used or create an .RCP file. Those RCP/RCS files can attach to Civil 3D drawing and create surface form it.Note: This article describes importing point cloud LAS file and not Layer State file from AutoCAD.

Importing Lidar files into Microstation V8i Offline Aldo Scasserra over 3 years ago Is it possible to import Lidar files into Microstation V8i to bring ground levels through? Under Select A Point Cloud File Format, select LAS. Under Files To Be Imported Into The New Point Cloud Database, click. In the Select File dialog box, navigate to the tutorial folder. Select Point Cloud.las. Under New Point Cloud Database, under Specify New Point Cloud Database, click. Importing as a data link: Open excel file downloaded from the link above and select table completely then right click and select copy from the contextual menu, you can also use CTRL+C to copy table. Now open AutoCAD and click on paste special from clipboard panel of the home tab as shown in the image below. Paste special window will pop up.

Is there any way to utilize legacy point clouds in Civil 3D 2018Within ArcToolbox, go to Data Management Tools LAS Dataset and select Create LAS Dataset. In the Create LAS Dataset window, Click on Input Files to choose the LAS file path. Also, choose for a location to store the LAS Dataset (.lasd) that you are about to create by clicking on Output LAS Dataset File.
Versions:
2019; 2020; 2018; You can export and import saved layer states to use the same layer settings in other drawings. Use the ExportLayerState method to export a saved layer state to an LAS file; use the ImportLayerState method to import a LAS file into a drawing.
Note: Importing layer states does not restore them; you must use the RestoreLayerState method to restore the layer state after it is imported.
The ExportLayerState method accepts two parameters. The first parameter is a string identifying the saved layer state to export. The second parameter is the name of the file you are exporting the layer state to. If you do not specify a path for the file, it is saved in the same directory in which the drawing was opened from. If the file name you specified already exists, the existing file is overwritten. Use a .las extension when naming files; this is the extension AutoCAD recognizes for exported layer state files.
The ImportLayerState method accepts one parameter: a string naming the file that contains the layer states you are importing. If the layer state you want to import does not exist in a LAS file, but a drawing file. You can open the drawing file and then use the ImportLayerStateFromDb method to import a layer state from the Database object of the other drawing.
When you import layer states, an error condition is raised if any properties referenced in the saved settings are not available in the drawing you are importing to. The import is completed, however, and default properties are used. For example, if an exported layer is set to a linetype that is not loaded in the drawing it is being imported into, an error condition is raised and the drawing's default linetype is substituted. Your code should account for this error condition and continue processing if it is raised.

If the imported file defines settings for layers that do not exist in the current drawing, those layers are created in the current drawing. When you use the RestoreLayerState method, the properties specified when the settings were saved are assigned to the new layers; all other properties of the new layers are assigned default settings.
