cross section

[Mirna]

how to get quickly cross section from a plan or a map?

[ReMark]

Welcome to the forum Mirna.

 

The plan or map. Is it an AutoCAD drawing file?

[Mirna]

ya, .

[rustysilo]

If you have Land Desktop or Civil 3D this isn't hard after a surface is created. Do you have either of these tools in your arsenal?

Mirna: Perhaps you could give us some details as this conversation really doesn't seem to be going anywhere fast. The more information we have the better our chances of helping you.

Try this...thanks to Pedro

QuickProfile.LSP

Thanks for the lisp lpseifert! I went to use it, but when it asked for my alignment, it didn't recognize it as such. What am I doing wrong here?

[lpseifert]

I just tried it using a polyline (not 3dpoly) and it worked fine.

Tried it again with a line as the alignment and this is the error I got

***Horizontal Alignment must be a LWPolyline***

Be sure the contours you are using have an elevation (Z-coordinate).

I have used this lisp before, and it certainly works.

 

One warning though, it seemed to not reset the EDGEMODE variable back to 0, and then afterwards, TRIM and EXTEND choose imaginary extensions of the cutting or boundary edge

 

Check EDGEMODE :wink:

[BOB'27T]

I'll give that a try. I thought it only would work with an alignment. I tried to make it harder than it needed to be. My contours had elevations of 8',9' & 10' (it's pretty low here).

That Lisp Rocks! I Love You!

A simple Thank You would suffice

Can someone please tell me how to use the attachment above, i am still a beginner in AutoCAD and i need to make some cross-section

[Ahmed84]

Can anyone please tell me how use the attachment above I am really new to Autocad and i need to make cross-section, I am using autocad 2010

Ahmed84: There is no need to repeat your question. Please show some patience. We are all volunteers here.

 

I haven't tried the lisp routine but judging from its name I'm assuming that a person can derive a cross-section cut through a series of contours.

 

Do you know how to run a lisp routine?

 

This is how the maker of the lisp program describes it:

"A Visual Lisp Routine that creates a section profile of the terrain based on the existing contours."

 

To run the program type the letters qp at the command line then press Enter. Follow the command line prompts. Keep in mind that when you are done you may have to reset Edgemode.

Sorry for the double reply, that was by mistake and for sure I appreciate any kind of help no matter what since we are volunteers, I managed to run the application and it went smoothly, very nice

 

thank you very much

[ReMark]

Don't thank me I really didn't do anything. Thanks really belongs to the person who took the time and effort that went into writing the lisp routine.

 

Well anyways, your problem seems to have been solved and that's the main point.

 

By the way, in the future you should really start a new thread and not add your question to a pre-existing thread. That way more people are apt to see it and respond.

 

In the rush to answer your question I forgot to say, Welcome to the CADTutor forum. Where are you located? Do you work in the civil engineering field or are you a student?

[Ahmed84]

Thank you very much, I am from the middle east and I am a geolgy major working in the mining industry:)
