Which one better?

Post by Oz4n »

Hello everyone, I'm a cad modeler. I'm using Solidworks since 11 years. I like learning constantly, so I have to always look for better.

I am using Geomagic Design X since two years. I wondered which one better? So, Do we have one better for reverse cad? My old friend said Delcam Powershape (for now Autodesk) do you think about powershape or another software?

Im assuming we are talking about pointcloud to bim here. I personnaly didnt like the tools within solidworks to work with a pointcloud,even with the pluggin. I tend to work with what I think is best and for me its autocad 3d. I just got very good with the ucs and all the types of extrusions and I like its overall compatibility, I also mapped a lot of maccros to speedrun myself to a final result,typing and clicking commands is very slow. Tools for manipulating a pointcloud are great. Overall you just have to get to know all the bugs and work arround them. I mix my work with edgewise. Edgewise for pipping / structural(often work with existing plans for the real elements names/diameter) then autocad for the more abstract forms(concrete, etc.) I can get a model out very quickly. Most models I do is for clash purpose or they often need a quick bim(no annotations needed) and not a pointcloud for their project. I dont do ISO bim models with annotations, only very quick BIM models. Others might have much better workflow,this is mine.

If we are talking about Scan to BIM as Leandre said, I think Revit and Recap is the best for 3D modeling from point cloud.We need to keep in mind that Revit is a Design based program and we are trying to use it for As Built. So you should expect issues. But for 2D modeling Auto CAD is still the best option.

Hi Oz4n,
Can you tell what are you looking for the best software for? As far as I understand you are doing reverse engineering using a point cloud, right?
Like many others here, I work more in Revit, Autocad and Arhicad, since we do architectural or mep projects in most cases.
Now our company is looking towards the development of new directions, so we began to study Siemens NX for reverse engineering. The price is expensive, but looks very promising in terms of modeling and part analysis capabilities. Have you tried it? Can you say something about the comparison with SolidWorks?

UPD. I saw that you are making models of military equipment. I used to make a photogrammetry model of helicopters and airplanes. Here is a small example of a high poly model that I made before
youtu.be/xextgx0ZBQc . If you need data like this for modeling, I have a lot of scanned military aircraft.

Rhino 3D of course :)
Try making this Plane from Autocad or Revit.
It is from a pointcloud.

Hello Mike, you can`t make that plane in Revit for sure. It is a meshed model and required totally different workflow and software skill! He said he is a CAD modeler.

Nice model! Seriously I could model that from a pointcloud within autocad 3d. It would probably take me a day or two. I never tried Rhino, I will add that software to my downtime researches

Hi Peyman,
There are no meshes in plane, it is a CAD model.
I start by extracting cross sections from the point cloud then create NURBS surfaces from the sections.

Hello All,

If you look at the link below we support point clouds for both Rhino and SolidWorks:

viewtopic.php?f=174&t=16749

In the pro version we will have Clash Detection very shortly too!

Can always email me at [email protected]

Hi, thank you so much for all answer. I think you misunderstood my job, i'am not 2D cad modeler :| sorry. We say cad modeler for 3D cad modeler and we say draftsman for 2d cad modeler in my country.

I'm sorry for not fully explaining my job to you but some of you have fully understood me. Yes i do reverse engineering using point cloud. I'll explain in full now.

In solidworks is not using point cloud, you can't get the cross-sectional area but You can get an approximate accuracy in a centered cloud of points. I am doing manuel this. There are nice add for solidworks, its name Geomagic for solidworks. I use it sometimes.

And Geomagic Design X it is excellent software but some things are too laborious and slow for a solidworks user.

I just looking for better.
