Name polygons and export to svg.... Correct workflow anyone?

[Anonymous]

Hello Autodesk community, 

Anyone can help me with this? 

Using Autodesk software suites, would be great if could just use AutoCad for it. 

What would the best workflow be for this? 

-Convert or redraw polylines to simple polygons. 

-Label each polygon with a unique code an id=xxxxxx or something that will survive the export process. 

So once exported to .svg format the label is in tact. 

Eg. <path d="M454.76,266.19h63a24.34,24.34,0,0,1,24.47,24.21h0V489.82A24.34,24.34,0,0,1,517.74,514h-63a24.34,24.34,0,0,1-24.47-24.21h0V290.4a24.34,24.34,0,0,1,24.47-24.21h0Z" class="map__space" data-code="exampleXXXXXX”></path>

-Then export to svg with origin in the top left corner to match svg's 

Anyone? 

Could really use some help with this.

AutoCAD doesn't deal with SVG....  which is a huge pity.  AFAIK, the  way to get from DWG to SVG is to export the DWG to DXF, then use Inkscape or some other program to convert to SVG.

Possibly look for a WMF to SVG converter - and WMFOUT the geometry you want.

Either way, I suspect you'll be doing most of the work in the SVG editor you're using, rather than in Acad.

Option D if it's a big deal, and has a _really_ large budget, is to hire a programming team to write an export interface from DWG to SVG with whatever bells and whistles you want.

Hi @Anonymous,

This is an interesting workflow. Can you attach a couple sample drawings so I can see this in more detail? I would wager that there are some LISP routines out there that can do the poyline>polygon conversion or at least get you started.

I also envision that you could attach some fields to capture the geometric data as well.

As far as getting to a SVG file format, why not export as an EPS file and then convert it outside of AutoCAD?

Draftsight exports SVG's.  EXPORTSVG is the command.

Thanks JGerth. 

We played with writing something to grab layers and merge them outside of AutoCAD then convert to SVG. 

However we realized after further playing around that DXF gives us a better output, plus there is more of a development ecosystem to work with. 

So now we are: 

- Redrawing in AutoCad simple polygons

- Exporting as DXF

- Importing into some custom JS that we can click and name. 

More accurate and easier for us to name outside of Autocad. 

Thank you for all your help. 🙂 

Im sure I will be back.

Thanks John 🙂

So we realized that we don't need svg. We made an assumption that svg was going to be the easiest for us to work with. But it seems that DXF is much better for us. So now we are exporting as DXF and then have built something in js. to click and name the objects.

Still working on the semi-automated way to convert lines to polygons. Not sure how that will go. We need very simple shapes, because we are just representing spaces like a shopping mall directory (kinda, gives you an idea at least).

We want to be able to take a floorplan and convert to simple polygons.Minimal vertexs/ points....

Do you know of anyway to easily convert lines to polygons?

Thanks John.

Hi @Anonymous,

Have you tried JOIN and then select all the lines?  This might work although you might want to do it on a bylayer basis or bycolor.

I have a very similar requirement to add names for space polygons for using it for a web platform. Can you suggest any formats other than SVG to fulfill this requirement? How did the DXF with JS work out for you? 

Best,

Tj

Whats being asked is quite doable, straight out of AutoCAD.  We have a good SVG writer so the question is where would the extra information be stored in the drawing.  Would this be text inside the boundary like Class:MapSpace or would the data need to be Xdata on the polyline.

Lastly for curiosity, what target would consume this SVG content, some web based application we're not aware of?

Hi Tj, 

The DXF's worked out well. We ended up importing them into a custom web application then naming them within the app and linking them with data straight out of a graph database. The result was great! 

We are using it now for leasing and sales management for the real estate industry.

Let me know if you have any other questions.

Cheers!

Hi Terry, 

Thank you for the response. I had forgotten about this thread. 
We ended up using DXF over SVG. If we had your experience with SVG's we might have saved some time, however, we had to make do with what we had/ knew at the time. 

We are happy with the result thus far. 

The DXF's can be imported directly into our web application and linked with a database. So we can provide building data currently only sales and lease data across projects or whole portfolios. It's in early stages at the moment, currently in beta. We are currently working on a front facing website for inquiries. 

If you would like any more information please let me know. 

Thank you again and all the best!
