3D Polyline to Alignment to make an RXL

[Richard_Greene]

Hey i was wondering how i turn a 3D Polyline into an Alignment so i can apply an assembly to it and create a RXL?

Thanks Richard

not familiar with an RXL

Go to the modify tab of the ribbon. Go to the Desgin panel and click the chevron arrow next to the title 'Design'. The panel drops to reveal the 3D Polyline to 2d Polyline command. Convert the 3d poly and you can go to the Home tab, expand the alignment commands and choose Alignment from Object.

SincpacC3D has the CreateAlignProf command to do this in one step.

Show off. 🙂

Richard, just kidding with Jeff above. Sincpac is a great product with a bunch of time saving addon function for C3D.

RXL?

Awesome thanks guys

RXL - Trimble Alignment

Wait. Do I still have to make a Profile to go along with this or is it made automatically?

If you're using the Sincpac tool then you would get the profile automatically.  Otherwise not - you'll have to create that separately.

Start by making a copy of the 3d polyline, and then convert that copy to a 2d polyline.  Use the Create Alignment from Object command to convert the 2d polyline.  Next you need to create a blank profile view so that you have a place to build the profile you need.  Make sure that you set the elevation range to accommodate the 3d polyline.  Use the project object to profile view command.  The final step is to create a new layout profile, tracing along the projected polyline.

I'm assuming that you already have the Trimble Link ribbon installed, and know how to export the new alignment / profile to rxl format.

Neil is smack on and has a good workflow but I would typically take the original 3d poly and make a surface with it and a stepped offset (feature line editing tools work on 3d polys) so I can work with a surface profile vs an object projection. If a surface boundary is needed due to segment deflection I would convert the 3dpolys to FLine and close it with two segments. This closed breakline can double as a boundary in the srf definition.

Please also note the flaw in the workflow if you convert the 3dpoly to soon....You will need those elevations for a projection or srf.
