Help on version 0.1Help on current version: 1.1Driving Dimension Tool
Use the Dimension Tool to place Driving dimension entities in your model. Activate the Driving Dimensions Tool from either the LDD Toolbar or the Tools menu.
Placing Linear Driving Dimensions
Linear Driving Dimensions are based on a 3D model. Linear edges can be used to set the driving dimensions. To set a dimension on the edge in your model:
- Select the Driving Dimension Tool. The cursor changes to an arrow.
- Click at edge, which you are to set dimension on.
- Move the cursor perpendicular to create a dimension string.
Note - Press the Esc key at any point during the operation to start over.
- Click the mouse to fix the position of the dimension string.
Tip - You might need to occasionally rotate your model, as you dimension, to position the dimension to the proper plane.
- A dialogue box appears пїЅ type the desired length in.
Placing Radius Driving Dimensions
To place a Radius Dimension on an Arc or Circle entity:
- Activate the Driving Dimension Tool. The cursor changes to an arrow.
- Click on an Arc or Circle entity.
- Move the cursor to pull a dimension string out from the model.
- Click the mouse again to fix the position the dimension string.
Changing Dimension
Activate Driving Dimension tool. Click on the driving dimension, a dialogue box appears, change the value of the dimension and click on «Ok» or press the Enter key пїЅ the dimension changes the length or radius of the object it associated with.
 If object length/radius cannot be recalculated due to a conflict with other dimensions Driving Dimension is displayed red.
Driving Dimension Entities
 Driving Dimension entities are finite lines with length information allowing you to quickly and effectively manage the key dimensions of your model. By using Driving Dimensions you can set edge length and arc and circle radiuse precisely. Set Driving dimensions with the Driving Dimension Tool.
Each Driving Dimension Object lies in its own plane, is determined by the entity, to which it is set, and the direction used when it was created.
Changing Driving Dimension Value
A Driving Dimension entity's text displays the value you set. By changing the driving dimension value you rule the length of edge or radius of arc/circle that dimension is associated with.
Recalculate Objects
 It is possible to edit geometry by other tools than Driving Dimension, so geometry does not satisfy the values set in driving dimensions. To correct this click on Recalculate Objects tool.
If some of Driving Dimension values cannot be satisfied, those dimensions are displayed red.
Hide Driving Dimension
 Use the Hide menu item to hide all driving dimensions. To unhide driving dimension click on this tool again.
