Section 5.2 CloudWorx for AutoCADIntroduction

CloudWorx for AutoCAD allows the user to view, measure, and draft against the point cloud directly from the AutoCAD environment without the need to load millions of points into AutoCAD directly. CloudWorx acts like a read-only external reference file to make AutoCAD believe it is only dealing with a few Pointblocksand not millions of individual points. Cyclone is actually running in the background performing all of the calculations needed to manipulate the point cloud. You do not need to have Cyclone installed on a computer to run CloudWorx. CloudWorx is a stand alone plug-in for AutoCAD.

Section 5.2 CloudWorx for AutoCAD1. Setting Up CloudWorx for AutoCAD

It is good practice to have a registered point cloud ready for CloudWorx. It should be set to your final coordinate system PRIOR to performing any work.

Deliverables should be determined well in advance of performing work in CloudWorx.

The .imp file should be on the local hard drive for optimum speed.

Open the AutoCAD program.

If not already attached as a menu item, attach CloudWorx.

Type Menuload in the command line. Then type CloudWorx in the to load custom file field. See figure 1.

Once loaded the CloudWorx menu will appear. See Figure 2.

Type UCS.


Type X to rotate about the X axis.

Hit the Enter key.

Hit the Enter key again to accept the default 90.Figure 1

Figure 2



In the Current UCS name type plan.

Hit the Enter key twice.

Type in S for Save in the Specify origin of UCSline. See Figure 2.

Hit the Enter key.

In the Enter name to save UCS or (?) line type in a name for the view. In this case we used bldg. See Figure 2.

Hit the Enter again.

If needed, regenerate the point cloud by clicking the Regenerate Point Cloud button.

When you are ready to turn OFF the Slice, go back to CloudWorx, Clip Point Cloud, Slice,and click OFF. The point cloud will re-appear.

Figure 1

Figure 2




You are now ready to start drafting.

Turn on ORTHO (F8) in AutoCAD to square the corners. Digitize what you would see with the typical AutoCAD commands.

These commands include but are not limited to:

Polyline

Copy

Mirror

Remember to save your drawing and save it often!


Section 5.2 CloudWorx for AutoCAD11. Additional Option to Align AutoCAD View

Below are instructions to alternative way to alignyour AutoCAD view to the ModelSpace.

Type UCS on the command line.

Type 3P for 3 point UCS.

Follow the prompts and pick a new 0,0,0 point.

Follow the prompt and pick a positive Xdirection. This will be the bottom of your drawing.

Follow the prompt and pick a positive Ydirection. This will be the left-hand edge of your drawing.

The UCS will align to those picks.

Type S and save your new UCS and name it 1.

Type VIEW on the command line.


In the View Manager window, Current View: Current Views area click Top. See Figure 1.

In the General field click on the Set Relative tofield, and in the drop down menu click on 1. See Figure 2.

In the View Manager window click the Set Current button. See Figure 3.

Click OK. See Figure 3.

This will set the view to match the UCS. You can always change back to the original UCS by using the above method.

Set Current button

Figure 1

Figure 2

Figure 3




Click Regenerate Point Clouds to reload the points.

Click and drag Hide Regions.

Select Hide Points Outside Fence.

This will clip out all of the points outside your

working area.

Note: The points are still in the file just masked

from view.

Change to a Front View. This is an AutoCAD view command.

Click Clip Points from Slice.

Click the Y slicing tool.



Pick a lower slicing plane, then an upper slicing plane.

Click TOP or PLAN view.

This will give you a trimmed PLAN view of the data and will allow you to trace the information as needed.

Use AutoCAD drawing tools, lines, polylines, arcs, circles, etc. to complete your drawing. All AutoCAD functions work since you are in an AutoCAD drawing.


Hide Regions Manager- Controls hidden areas, on, off, and delete.

Hide Inside Fence- Options are draw a fence as a rectangle, polygon, or a circle.

Hide Outside Fence- Options are draw a fence as a rectangle, polygon, or a circle.

Restore Inside Fence- Restore points drops the fenced area and the point cloud returns to view.

Restore Outside Fence- Restore points drops the fenced area and the point cloud returns to view.

Restore All Hidden Points- Multiple hide regions are possible.

Hide regions can be used in conjunction with Slicing.

Section 5.2 CloudWorx for AutoCAD12. Hide Regions Toolbar Definitions


Section 5.2 CloudWorx for AutoCAD13. Using Fit Section Tool

The Fit Section tool allows you to trace a cross-section of a road, building profile, floor plan, etc. and snap the line work to the point cloud. In an AutoCAD drawing, load the desired ModelSpace.

Set a UCS so that the roadway is vertical on the screen.

Make a slice across the roadway, perpendicular to the centerline of the road.

View the slice from a front view.

Trace along the point cloud with a polyline to define the road cross-section. Use moderate care, add only as many vertices as necessary to define the road surface.


Section 5.2 CloudWorx for AutoCAD13. Using Fit Section Tool

Click on the Fit Section tool and then pick the polyline you just drew. CloudWorx will adjust the polyline to fit the point cloud and will center the polyline along the exact center of the slice.

Assign the polyline to a layer and turn off that layer to keep aclear view of the data.

Advance the slice to the new cross-section location and repeat the process.

HINT: To slice at regular intervals, set up a tic-mark along your centerline. Offset the tic-mark .5 feet. Use the AutoCAD Measure command to set the tic-marks along the centerline. When slicing, pick the first tic-mark for the first slice line and the offset tic-mark for the second slice line. View from Front and continue creating cross-sections.

Alternatively you can offset the first line to establish the cross-section thickness (ex: .5 feet). To move 10 feet to the next cross-section, click the Move Forward icon 20 times.


Section 5.2 CloudWorx for AutoCAD14. Using Fit Pipe to Cloud Tool

Fit Pipe to Cloud tool allows you to create cylinders from the point cloud directly in AutoCAD. You can create just centerlines as well.

Select the Fit Pipe to Cloud tool. Options are rectangle, polygon and circle. Choose the rectangle for this example.

Drag a rectangle over the straight pipe in the point cloud. Release the button and CloudWorx will draw in a centerline (or cylinder). Repeat until you have created a centerline for each section of pipe.

Use the Connect Pipes tool and select your centerlines (in sequence) to join all straight centerlines together.


Section 5.2 CloudWorx for AutoCAD15. Drawing Completed

Once your drawing is complete, close the ModelSpace View.

NOTE! You must PURGE the ModelSpace View from the AutoCAD drawing for use on non-CloudWorx computers. To do so, from the CloudWorx menu bar click on the Purge option.

You can always re-attach the ModelSpace to the drawing using the Open ModelSpace command.
