Using Coordinated Geometry (COGO) to Increase Drafting Speed

Coordinated Geometry, otherwise known as COGO, allows you to quickly and accurately place geometry given specific coordinates. VectorWorks has a lot of this functionality built in to the application simply using a combination of 2D and 3D tools. Additionally, learned to use the Data Display Bar in conjunction with these tools will allow you to draft much quicker.

Here’s a summary of some COGO operations and how to do them in VectorWorks.


Insert point by coordinates

Double-click on the 2D Locus or 3D Locus tool to either create 2D or 3D locus points.


Insert point by clicking

Use the 2D or 3D locus tool and click in the drawing to insert point.


Insert line with bearing or azimuth

Double-click on the Line tool to bring up the preferences dialog box. Highlight the "polar" button to get polar style L/A coordinates.


Insert multiple points along a line or curve

Use the Line into Segments… and Arc into Segments... commands respectively to break the lines or curves into segments. To just place a point at a specific interval along a line, use the Snap Distance constraint with Multiple Divisions enabled and a locus point.


Curves: create curves through 2 & 3 points, between 2 intersecting lines, by parameters (radius, entry bearing, tangent, external, arch length, etc)

The Arc tool does all of these, some just using the modes on the mode bar. Simply double-click the Arc tool for coordinate entry.


Boundary: select any points/lines in order and define a boundary

The Property Line object will do this (by points), as will its accompanying tool, Property Line Tool (by clicking a starting point and entering data). Points Coordinates transformation: rotate around a point, translate, increase elevation by, etc

Enter your points as 3D loci using the 3D Locus Tool. You can group them and then rotate, move, or elevate them together. Then ungroup if you want.
