AutoCAD Map 3D 2013 - Editing DXF maps

Those of you in the Oil & Gas biz - please help! I'm new to AutoCAD, and especially new to AutoCAD Map 3D. I need to make a plat showing a well location. When using Petra or DrillingInfo, a map can br printed to a DXF. DrillingInfo puts out a DXF with just the 0 layer, and the well spots come in as polyline circles. The DXF Petra puts out opens with different layers and symbology, which I like. It's just that the well spots are blocks, which I do not understand. When I open the Petra map with AutoCAD Map 3D, my well spots are unitless block references, and are tiny specks. I need to resize them so they can be seen. Why can't I figure this out??

Your blocks are using different units.  They are being scaled (0.293).  You can change the scale in the properties window (all 4 at once since they have different names).  That is a quick and easy fix for a 1 off.

 

A more permanent fix is to make sure the block definitions are using the same units.  Note that this just doesn't work with lat/long.

I tried changing the x and y scales to 100, and it still doesn't seem to change. Does the Block Unit being "Unitless" have an effect on this?

Thanks for your help!

NP.  You have to make sure the units are "unitless" before you dxfin (create a template if you have to do this several times).

 

You can also try block edit in the destination file, but it's a PITA if there are several blocks with different names.  You can also create a block with a big yellow circle or something and use block replace (xpress tools).

So I opened a blank dwg, set the units to unitless, then used command dxfin, and selected all the well blocks. I changed the x and y scales to 100 in the properties window, but this only changed the size of two of the block references. The remaining blocks are still specks. All the blocks appear to have the same properties in the properties window. Do I need to make some changes elsewhere?

Does a Match Properties (MA or MATCHPROP command) from the desired looking block to the tiny one change results?

What about a REGENALL?

Or do the blocks start to look alike after you save, close, and reopen the drawing?

I'm thinking the blocks are made up of autocad points with the point symbol not set to a symbol that you can see, Type in  DDPTYPE and pick a different symbol and/or PDSIZE and set the size up.

Not sure if it matters but you have not set a coordinate system in the map in your screen shot.  Is there a CS involved somehow?  Possibly it needs to be set before or after the dxf data is added?

The Petra map that I exported the DXF out of is set to NAD 27 Texas State Plane South Zone. When open the DXF in Map3D no CS is assigned. Therefore, I guess the DXF does not contain a spatial reference? Either way I tried assigning the CS in Map3D, but it does not seem to change the blocks. I then tried changing the units feet since I set the CS to State Plane, but that doesn't seem to help either.

Just tried MA, and it didn''t change anything. That's probably because all properties in the Properties window are already all the same for each block reference. I went ahead and did a REGENALL, saved, closed and reopened. No change.
