Rectangle 3 Points- Center / Corners


This topic will explain the Rectangle 3 Points - Center / Corners function,will explain where to find the function, and explain the options foundin it.This topic will also give a brief description of Dynamic Drawing,the Snap Increment function, explain creation with quick steps, and providelinks to related topics.

The Rectangle 3 Points - Center / Corners Function

The Rectangle 3 Points - Center / Corners function is used to createrectangles using sketching, data entry, or a combination of both.

Dynamic Drawing

This function supports Dynamic Drawing which allows you to use a combination of sketching and data entry to create the entities. After initially sketching the entity, it becomes an active entity, which is an entity that is in Modify Mode. Entities in Modify Mode display in the current Entity color, but displays with a greater line thickness to make them easier to identify. Active entities can be modified using data entry. The benefit of Dynamic Drawing is that you can quickly sketch a point to get the approximate result and then use data entry to update to the exact dimensions, and coordinate values as needed.


Entities in Modify Mode

Final Entities


In the images above, we see entities which are still in Modify Mode, followed by those same entities after they are finalized.

Snap Increment

This function support the use of the snap increment when selecting the location of the entities. The snap increment allows you to get precise results when using mouse selection and helps to reduce data entry modifications.

To open Rectangle 3 Points - Center/Corners:

  • In the Shapes group, of the Create 2D ribbon,click the down arrow under Rectangle, and select Rectangle 3 Points - Center/Corners.

The parameters display in the Data Entry Manager.

The Data Entry Parameters

Creation Options

The Creation Options allow you to select between different methods for creating rectangles in the same dialog.Click the associated icon to utilize the particular creation option.




  • Length (X) - sets the length of the rectangle along the X-axis of the Active UCS.
  • Width (Y) - sets the width of the rectangle along the Y-axis of the Active UCS.
  • Angle - allows the rectangle to be rotated around the origin.



Base Point

The Base Point determines the coordinate location of the rectangle using the XYZ coordinates of the active UCS. The selected origin location determines where the origin is on the entity.


  • X - is the X-axis location of the entity origin.

  • Y - is the Y-axis location of the entity origin.

  • Z - is the Z-axis location of the entity origin.


Tip: The XYZ coordinates are in reference to the active UCS, or user coordinate system.



Corner Type


  • Sharp Corner - creates the rectangle with sharp corners.

  • Radius - creates the rectangle with round corners using the Radius value.

  • Chamfer Length - creates the rectangle with chamfered corners using the Chamfer value.



  • OK - finalizes the function.

  • Cancel - exits the function.

Quick Steps

  1. Open the function.

  2. Click a snap point or anywhere in the graphics areato set the center point of the rectangle.

    You can modify the snap incrementvalue or turn it off while selecting locations with the mouse.

  3. Movethe mouse pointer and click a snap point or anywhere to set the lengthof the rectangle.

  4. Movethe mouse pointer and click a snap point or anywhere to set the widthof the rectangle.

    This is now the active entity, whichmeans that it is not fully defined.

  5. Dynamic Drawing allows you to update the Data Entryparameters to modify the active rectangle.

    After updating the Data Entry parameters, to finish the active entity,you can click OK or startsketching the next rectangle.

    When you don't need to update the Data Entry parameters, you can justclick to start the next rectangle.

Tip: Thereare many ways to finish the active entity: click OK, press Spacebar, orclick in the graphics area to start the next rectangle.

  1. Repeat this process for all rectangles to be created.

  2. To close the function, click Cancel.
