can not extract point coordinate

Anonymous — Thu, 26 Nov 2020 05:19:02 GMT

I have few points in civil 3D, andI'm trying to use "extract data" to extract the x,y,z coordinates. However it's not working.

Does anyone know the reason?

Hi @Anonymous,

Welcome to our community! Thank you for reaching out in the Autodesk Forums. This is a great platform where you and the rest of the community can benefit. I need a little more information from you.

When you mention points, are you referring to AutoCAD points or Civil 3D COGO points?
Are you using DATAEXTRACTION (Command) when you said "extract data"?
Can you attach some screen shots, screencast and/or .dwg for us to take a look?

Hi Wendy,

Thanks very much for your reply.

It's civil 3D Cogopoints.

I'm using command dataextraction. I want to extrac the Cogopoint coordinates to Excel file.

Please see the following image for your reference. I'm extracting a point data, however the coordinates data are not shown in this page.

Thanks very much.

@Anonymous,
Welcome to the Autodesk Forums.
I think DATAEXTRACTION only works on AutoCAD Objects, not Civil 3D Objects. I might be wrong on this, but I tried just now, and the command doesn't seem to recognize COGO Points. For COGO Points you'll need to use use Export Points.

Dear Dave,

Thanks so much for your answer.

I have another question, hope you can help me.

Is there a way to mark points on a polyline at specific interval?

For example, I want to make some points at 0+020, 0+052, 0+063, 0+122 on a polyline.

Thanks.

@Anonymous,
"Is there a way to mark points on a polyline at specific interval?"
Yes, but you'll first need to convert the polyline to an alignment. Then you can use Create Points - Alignments >> Station/Offset or Create Points with 'SO (Station Offset) Transparent Command.

Hi, Dave,

It's clear now.
