MAPEXPORT in AutoCAD Civil 3D 2010

Hey everyone! Happy Friday! I don't know how many of you are using the Map 3D functionality in Civil 3D, but something has been brought to my attention this morning. If you use the MAPEXPORT command in Civil 3D 2010 to create an ESRI shape file, the shape file is empty. The Export Dialog box is missing the portion for you to where you select the object type. Selecting objects on the screen won't work because the object type has not been set. So, what do you do? Well, go here. This link will take you to the page to download a new MapExport.ini file and will give you the instructions on where to put the file to fix the dialog box.

An Update to Transparent Hatches

Hey everyone. Happy Halloween! I received a comment to the Transparent Hatches post from last month. After reading the comment, I tried to create the transparent hatch and plot it from my local printer. Much to my chagrin, the hatch that shows up transparent on the screen plotted a solid colr blob on my printer.

Well, that got me to thinking and doing some more research on the topic. I called on Alacad's resident Map 3D specialist James Murphy. I told James the steps that I had gone through to create the "transparent hatch." I asked him the all important question of how can I get this transpaernt theme to hatch. James informed me of a command that is new to the 2009 version of Map 3D, which means that it also works in Civil 3D. The command is MAPPLOTTRANSPARENCY. When you enter this on the command line you have the option to turn it on or off. Turn the command on. I sent the current drawing file to my local printer and lo and behold, the hatched area printed transparently! To get this to work on your local/network printer/plotter, you may have to adjust the line merge properties of the printer/plotter. This setting can be changed through the printer properties button on the plot screen. I hope this helps! Happy plotting!

Transparent Hatches

Hey folks! It has been a while again. I have been traveling quite a bit as of late and haven't taken the opportunity to write. I wanted to share something that I came across yesterday morning. I was trolling the Autodesk Civil 3D website and downloaded Luy Kuhn's "Tips and Tricks" webcast. While watching the webcast a support call came to mind. I received a call some time ago about creating transparent hatches. A customer had an aerial photograph that he had referenced into a drawing and was wanting to put some solid color fills in certain areas for a presentation he was doing. The problem was that the solid fill hatches came out as solid color blobs on his plot. Definitely not what he was looking for. We tried various things to get it to work to no avail. We finally gave up and decided that it couldn't be done very easily.

Well, have I got something for you! As I said I had been watching the webcast and Lucy decided to show how to create a transparent hatch. The method involves using the shrinkwrap command to create a closed polyline around a hatch pattern. Then the pattern is erased and the shapes are exported as SDF data. Using FDO Connect in Map 3D the data was queried into the drawing and a theme was applied to it. In Map 3D you can change the transparency of a theme by moving a slider bar! It was definitely easier than anything I had seen or tried.

If you want to see a clip of Lucy creating these transparent hatches peruse over to the Autodesk Civil 3D website and click on the Civil 3D Resource Center Link. You will have to register to view the content, but I think it will be worth it. There are other short vids of Lucy showing different functionalities of Civil 3D. A lot of information can be found there. Take a look when you get a chance!
