Converting Drawing Objects to Survey Points

Every drawing object has at least one coordinate point. For a text object, this is the text insert point. For a circle, this is the radius point. Objects like lines and polylines have additional coordinate points. When you convert drawing objects to survey points, TPC creates a survey point for each coordinate point of the drawing object and adds the survey point to the survey. It also creates a traverse point and appends it to the traverse you select.

Once the survey points have been created, you can use them for stakeout, COGO or anything else.

Reading CAD Files

You will use this feature to convert objects you've imported from a CAD file into useful survey points.

TPC can import DXF files, DWG files, Shape files and DGN files (DGN files are supported in the Professional Edition only) created in other programs. Once imported, you can convert the objects you want into survey points. Let's say that you have imported the construction drawings for your project. You can convert objects like curb lines, utilities, etc. and then export them to your data collector or total station for stakeout.

Because you can place converted points in any traverse you want, you might want to create a traverse just for the curb lines and another traverse just for utilities, etc. Now you can use the traverses to help organize your stakeout data. It's a great system.

Converting a Single Object

TPC creates one or more survey points, depending on the object, and appends them to the selected traverse.

Converting Selected Objects

TPC creates the survey points for the drawing objects in the order you selected them and appends them to the selected traverse.

Converting all the Objects on a Layer

You can also convert all the objects on a layer to survey points. This option is useful when you have imported a DXF file. You can, for instance, highlight any object on the STORM_DRAIN layer, and create survey points for all of the storm drain objects.

This option works best if the drawing uses rigorous layering rules where all the objects of a certain type reside on the same layer (i.e. all the curb objects reside on a CURB layer, all the utility objects reside on a UTILITY layer, etc.).
