Autocad 3d map Shape Export

[Fleww]

Hey I got regular 3d map shape export, but when I open it in Qgis i just don't see it, I can only zoom in feature by attributes. What am I doing wrong? Please help I got crazy about this last 3h trying to make it.

I see I got some coordinate Issue but I put good zone and everthing.

I guess this is this issue but i really cant find 28532 and duplicate. I dont have it in autocad map. 😕 please help.

Hi @Fleww,
Thanks for posting your Shapefile.
"...got some coordinate Issue..."
That's first up. I don't think you use Feet over there. And I can't find EPSG:28532. It's not on the EPSG site.

@Fleww,
The PRJ with your Shapefile shows a "Double_Stereographic" Projection.
The Amersfoort-RDNew(EPSG:28992) Projection in MAPCSLIBRARY matches all the parameters in the PRJ except it uses an "Oblique Stereographic" Projection.
Your Shapefile certainly seems shifted 32,000,000 Meters away from Bing Live Maps Extents.
Where did you get that Shapefile?

direct mapexport from autocad 3d map.

Ok, so what I can do?

This is that problem. Autocad dont have this coordinates. This post dont solve my problem. I cant belive that Autocad doesnt have it. I transfer coordinate online from some online website from my dwg and i got perfect shape, all it takes is EPSG:4647.

I got crazy about this cant belive Autocad still didnt fix it its 2022.

@Fleww,
There is no "28532" or "4647" in MAPCSLIBRARY. (EPSG:4647 is ETRS89/UTM zone 32N (zE-N)) There is a ETRS89.UTM-32, which is a Transverse Mercator Projection. You can duplicate and edit that one, re-naming it "ETRS89/UTM zone 32N (zE-N)" but you still have a problem with the PRJ of your Shapefile--it shows a "Double_Stereographic" Projection. Where did you get that Shapefile? Does it represent administrative units? You can get a Shapefile in EPSG:4326(LL84) from >>>Here<<< and your problem is over.

@Fleww,
OK, here you go. Attached please find CSLibrary_ETRS89.UTM-32N_Z_CS.XML. Use Command >>>MAPCSLIBRARYIMPORT<<< to add it to your MAPCSLIBRARY Definitions. Then when you assign ETRS89.UTM-32N_Z Coordinate System to your drawing, your shapefile plops in at the correct place.
I used instructions that you linked and verified parameters at >>>EPSG:4647<<<.

OmG perfect man thanks alot!! ❤️

Your site is in Kronshagen, correct?

Kronshagen.

Your have two issues:

1. The shapefile’s is using a projection for the Netherlands but your site is in another country. 
2. The shapefile’s projection is not in Map3D’s coordinate system library. 

You’ll need to perform two tasks. First you’ll need to add the coordinate system known as EPSG 4647. Then you’ll need to add the shapefile to your drawing and at the same time, overwrite the old CS and use the newly created CS in its place. This is how you can do the tasks. 

You’ll create a new CS. Instead of creating one from scratch, you’ll make a copy of an existing CS then make modifications to it. You’ll be making a copy of a CS that’s ‘similar to your’ area because this copy shares some of the same parameters as the one you’re about to create. Your goal is to save the CS in the library so it’s available for you to use in a later part of this procedure. 

1. Open the Coordinate System Library.

2. Make a copy of ETRS89.UTM-32N. Select the copied CS then click the EDIT button. Perform steps 1 thru 5 exactly as shown below. 

3. On the Coordinate System page make the changes exactly as shown below.

4. On the Projection page make the changes shown below then click the SAVE button. Exit the Coordinate System library. You will assign a CS to modelspace next.

5. Back in your drawing, use MAPCSASSIGN command to give model space an ‘assigned’ coordinate system. Search ETRS89.UTM then highlight ETRS89.UTN-32N (EPSG 25832) and click the ASSIGN button.

6. Next, open the Data Connect palette (MAPCONNECT) then click Add SHP connection and Connect. The shapefile will display Netherlands-RDNew which is INCORRECT. Click Edit Coordinate Systems as shown below.

7. Highlight RD_New under the name column then click Edit as shown below. Search for ETRS89.UTM32 then select the ‘new’ Coordinate System you just created. The Override column will now displays the new CS. Click OK.

8. Back in the Data Connect palette your shapefile’s coordinate system MUST display coordinate systems as shown below. Note: the modelspace CS and shapefile’s CS are not the same. Click Add to Map button then turn on Bing Hybrid.
