We use 3D Scanning to reproduce exiting parts into CAD
What is 3d Laser Scanning parts?
Laser Scanners are tools that collate information of a shape by using Laser and Images. The data collected (in a Mesh Cloud format) can then be used to reproduce 3D CAD Models. It should be noted that it is not as simple as just scanning an item and one then has a 3D CAD model. The format of a Laser Scan can only be used as a reference model.
Laser Scanning is a fast, accurate and safe non-contact method of capturing the dimensions of a physical object in the form of a digital point cloud. The point cloud can be used to create a 3D CAD model which can be exported into all major CAD packages. Some of the most common uses for Laser scanning include Engineering Design, Reverse Engineering, Heritage preservation, quality control and As-Built documentation. Laser Scanning can replace the need for most manual on-site measuring.
The creation of a new 3D CAD model from a Laser Scan usually involves the following steps:
- Prepare and Laser Scan Part
- Clean Up scan data
- Using Scan Data as a Reference create the fresh 3D CAD model
How do we 3D Laser scan part to reproduce the components on 3D CAD?
We Laser Scan parts that require Reverse Engineering. With the scanned data we create fresh 3D CAD model in CAD software packages such as Solidworks. From the 3D CAD model, we are then able to create new Manufacturing Drawings.
Our main services include:
- Scan and supply cleaned up Mesh Data
- Scan Part and create new 3D CAD Model
- Scan Part, create new 3D CAD Model and produce manufacturing drawings
We offer 3D Laser Scanning Services including 3D Cad Drawings, 3D Laser Scan BIM and 3D Modelling Services.
Our CAD draftsperson/3D Modelling/3D Laer Scanning Technician possesses the following qualification:
- Strong experience in using Various CAD software.
- Sound knowledge of procedures, principles and techniques of mechanical drafting.
- The ability to capture Laser Scanning data and process cloud point data.
- Utilize industry-standard hardware/software such as Leica P16, Cyclone, 3DReshaper
- Skilled at solid modelling and 3D features of drawing and designing.
- Ability to create drawings in alliance with company standards
Our first step is to make a site visit and start scanning. By setting the scanner up in six different locations we shall able to collect the necessary number of points for the detail level we would after. Each scan shall take approximately six minutes and if there is more number of flat surfaces, targets will not be used. The majority of the time will be placing spherical targets as well as checkerboard targets to help your registration software “stitch” the scans together.
Once our scans complete, our site visit shall be done and back to the office to start registering our scans.
There are several point cloud registration software options out there. We used various packages depends on size of the project. The registration process normally completed the same day.
- Launch the software
- Import the files from the scanner
With a registered point cloud, We can use our software to make the task more manageable. Dumping the entire cloud into 3D modelling software, in most cases, is not possible due to the sheer size of the file. We can use the software to segment the cloud into more bite-size pieces which are easier for CAD modelling software to digest. This takes only minutes with the included tools in the software.
Now With specific sections cut out of the model, We can import them into 3D modelling software and start modelling walls, doors, windows, structure, etc. Modelling time can vary greatly on how much or how little detail we are trying to get to out of the scan.
The advantage of having the cut sections from the registered point cloud is that we have a template to follow. We typically start with the easier items first; walls, floor, and ceiling. We then go after, in this case, the structural system. The trusses were modelled once and then copied and pasted.
Once the bulk of the walls and structure were complete We will able to create some cut sections and a ceiling plan.
Drafting Design Tools and Software
Our Expert Engineers & Drafters are versatile enough to use any software that your process might require. We have successfully managed Drafting and Design projects involving software such as AutoCAD, ArchiCAD,Solidworks, Revit Architecture, Architectural Desktop, Microstation, and 3D Studio Max.
