I have been working with Leica HDS Laser Scanners since 1999. My company is a Leica HDS GOLD dealer and we specialize in implementing scanning and creating deliverables utilizing Leica HDS and Autodesk software. Over the past few years the typical solution(easy) is to work with PTS file format and it does provide a solution, but we can also convert the PTS format to LAS or E57 format. We are located in Michigan and MDOT requires a LAS in their RFP.

We recommend exporting Leica HDS IMP data in pts format and converting it to a LAS file for importing into Civil 3D or REVIT. This will reduce the file sixe by almost 75%. To convert the PTS to LAS we can utilize a very simple and free software called POINTZIP. Yes this is free software and yes the icon is a DUCK. I was afraid to download this free software with the .exe extension and the picture of a duck., but now after testing this product I give my stamp of approval. now.

Download while it is FREE

During the conversion process color can be retained if you select the xyzRGB option below.


Once Civil 3D is open, simply right click Pointclouds from the Prospector and Create Point Cloud. From Revit, select insert POINTCLOUD, select the las file and convert to PCG.
Select Truecolor to display Pointcloud color from the images that were taken. Below is an image of what to expect once the pointcloud is imported.
 We plan to elaberate on our next post about the advantages and disadvantages of points directly imported into Civil 3D or any Autodesk format. We will also provide solutions for importing pointclounds into Revit, Navisworks, and Factory CAD. We will also provide solutions and workflows for working with the new E57. E57 file format is a compact, vendor-neutral format for storing point clouds, images, and metadata produced by 3D imaging systems, such as laser scanners.
Happy Holidays to all!

ALL I want for Christmas is a Civil 3D APP. I have been looking at these and wanting to test them forever. Now that Autodesk University is behind us it's time to start playing again. Please post if you have downloaded any APPS and feel free to review them here. I will begin my reviews the first of the year.  http://apps.exchange.autodesk.com/CIV3D/Home/Index

 My favorite so far is the E57 file format for pointclouds. I will discuss this more on my next post along with the LAS file format for pointclouds in Civil 3D.

E57 file format plug-in for Pointclouds in Civil 3D 2013

The next review will be makinga copy 3D polylines/Featurelines and placing them in 2D.

Civil 3D Medians and Curb Islands made easy in CORRIDOR

Autodesk University was great again this year. My biggest regret was not meeting with every client that was lucky enough to be out there. I would also like to thank the clients that did hangout. First year that the CRAPS table thanked me for coming to AU.

I spoke for the 4th year in a row and the title of my class was AutoCAD® Civil 3D®: "Curbing" Your Enthusiasm. I presented Conditional corridors for driveways, ADA ramps and sidewalks. I also provide a SOLU-AROUND for medians. Below shows a small portion I presented about medians. I will provide the ultimate part about my class after this solu-around.
This method of creating medians was not practical until the 2012 version. In version 2012 we can add multiple baselines alignments to a single corridor and all assemblies show up together in cross section view. So why not create alignments from each island and use the corridor surface as the profile? This would be dynamic and update as the corridor changes. Unfortunately Civil 3D corridors will not accept the elevation from the corridor profile. Solu-Around, create a new surface called medians. Now paste the corridor surface into it.

·         Create a corridor surface
·         Create a surface called medians
·         Paste the corridor surface into the medians surface
·         Create alignment from the edge of pavement around the median
·         Create profile from median surface.
·         Create assembly using only curb attached to the assembly
·         Add the alignment, profile and assembly to existing corridor
I will post part of the AU class or recorded Solu-Around at ADSKSolutions.com I will provide
direct link here.
