Constraining Pattern - Copied Objects
Available in TurboCAD LTE Pro / DoubleCAD Pro only
This section refers to objects copied in patterns (lines, linear arrays, radial arrays), using the Copy Entities tools (see Copying Objects).When you copy objects in a pattern, you can use Auto Constraints and dimension variables to control spacing, angles, etc.This example uses a circle copied into a linear array.
- Before you begin, make sure Auto Add Constraints is active in the Inspector Bar.Unable to render embedded object: File (worddav453b54ac611f053fb12d317aa77ee296.png) not found.
- Create a rectangle and add a small circle. The rectangle should have parallel and coincident constraints assigned automatically.
- Select the circle and use Fit Linear Copy to copy the circle into a grid. (See Fit Linear Copy
- Assign some Orthogonal dimensions as shown. (See Creating Dimensions).
- Open the Calculator palette (F2) and the dimensions should be shown, identified by a variable. In this example, the variables were assigned names (L, E1, E2). ----Note: For more information on working with variables, see Calculator Palette - Variables
- Create a formula so that the two edge dimensions will be equal. In this case, the variable E1 was used as the formula for E2.
- To fix this, activate the Parallel constraint and click first the array constraint line, then the top line of the rectangle.
