Optimize your Calcs Builder templates for faster loading, smoother interactions, and better user experience. These tips will help you create efficient, responsive templates.

​
Template Structure Optimization

​
Organize Content Efficiently

Best Practices:
  • Limit Widgets per Page: Keep pages to 20-30 widgets maximum
  • Use Sections: Group related content into logical sections
  • Progressive Loading: Load complex content only when needed
  • Logical Flow: Organize content from simple to complex
Example Structure: 
✅ Good: Inputs (10 widgets) → Calculations (15 widgets) → Results (8 widgets)
❌ Poor: All 50 widgets on one page

​
Minimize Page Complexity

Guidelines:
  • Simple Pages: Basic inputs and outputs
  • Complex Pages: Advanced calculations and analysis
  • Reference Pages: Lookup tables and documentation
  • Results Pages: Summary and reports

​
Widget Optimization

​
Input Widgets

Performance Tips:
  1. Use Appropriate Types: Choose the right widget for your data
    • Number inputs for numerical values
    • Dropdowns for limited options
    • Text inputs for free-form data
  2. Set Reasonable Defaults: Provide sensible default values 
    // Good defaults
beam_length: 20 ft
material: "Douglas Fir-Larch"
safety_factor: 1.5
  3. Add Validation: Prevent invalid inputs early 
    // Validation rules
beam_length: min=1, max=100
safety_factor: min=1.0, max=3.0

​
Equation Widgets

Optimization Strategies:
  1. Break Complex Calculations: Use intermediate variables 
    // Instead of one complex formula:
stress = (load * length * 12) / (width * height^2 / 6)

// Use intermediate steps:
moment = load * length * 12
section_modulus = width * height^2 / 6
stress = moment / section_modulus
  2. Avoid Redundant Calculations: Don’t repeat the same calculation 
    // Bad: Recalculating the same value
widget1: area = length * width
widget2: perimeter = 2 * (length + width)
widget3: area = length * width  // Redundant!

// Good: Use the existing variable
widget1: area = length * width
widget2: perimeter = 2 * (length + width)
widget3: display_area = area  // Reference existing variable
  3. Use Conditional Logic: Only calculate when needed 
    // Only calculate if inputs are valid
stress = IF(length > 0 AND width > 0, load / (length * width), 0)

​
Lookup Widgets

Performance Considerations:
  1. Limit Lookup Size: Keep lookup tables under 1000 rows
  2. Use Indexed Data: Ensure lookup data is properly indexed
  3. Cache Results: Lookup results are cached for better performance
  4. Add Defaults: Provide fallback values for failed lookups

​
Calculation Optimization

​
Formula Efficiency

Best Practices:
  1. Simplify Expressions: Break complex formulas into steps 
    // Complex formula
result = (a * b * c) / (d * e * f) + (g * h) / (i * j)

// Simplified with intermediate variables
numerator1 = a * b * c
denominator1 = d * e * f
term1 = numerator1 / denominator1

numerator2 = g * h
denominator2 = i * j
term2 = numerator2 / denominator2

result = term1 + term2
  2. Avoid Expensive Operations: Minimize use of complex functions 
    // Expensive operations to minimize:
- Trigonometric functions (sin, cos, tan)
- Logarithmic functions (log, ln)
- Power functions with large exponents
- Iterative calculations
  3. Use Built-in Functions: Leverage Calcs Builder’s optimized functions 
    // Use built-in functions when available
max_value = MAX(value1, value2, value3)
min_value = MIN(value1, value2, value3)
average = AVERAGE(value1, value2, value3)

​
Conditional Logic

Optimization Tips:
  1. Short-Circuit Evaluation: Put most likely conditions first 
    // Put most common case first
result = IF(condition1, value1, IF(condition2, value2, default_value))
  2. Avoid Nested IFs: Use switch-like logic for multiple conditions 
    // Instead of deeply nested IFs
result = IF(type == "A", value_a, IF(type == "B", value_b, IF(type == "C", value_c, default)))

// Use a lookup table or mapping
result = LOOKUP(type, {"A": value_a, "B": value_b, "C": value_c}, default)

​
Data Management

​
Lookup Tables

Optimization Strategies:
  1. Keep Tables Small: Limit lookup tables to essential data
  2. Use Efficient Keys: Use simple, unique identifiers
  3. Index Important Columns: Ensure frequently searched columns are indexed
  4. Cache Results: Lookup results are cached automatically

​
External Data

Best Practices:
  1. Minimize API Calls: Cache external data when possible
  2. Use Efficient Queries: Optimize database queries
  3. Handle Errors Gracefully: Provide fallback values for failed requests
  4. Update Strategically: Only update data when necessary

​
User Experience Optimization

​
Loading Performance

Tips for Faster Loading:
  1. Lazy Load Content: Load complex sections only when needed
  2. Optimize Images: Compress and resize images appropriately
  3. Minimize External Dependencies: Reduce reliance on external resources
  4. Use Caching: Leverage browser caching for static content

​
Responsive Design

Guidelines:
  1. Mobile-Friendly: Ensure templates work well on mobile devices
  2. Touch-Friendly: Make interactive elements easy to use on touch devices
  3. Responsive Layout: Adapt layout to different screen sizes
  4. Fast Interactions: Ensure buttons and inputs respond quickly

​
Advanced Optimization

​
Python Solvers

Performance Considerations:
  1. Optimize Algorithms: Use efficient algorithms in custom solvers
  2. Limit Iterations: Avoid infinite loops and excessive iterations
  3. Cache Results: Store results for repeated calculations
  4. Handle Errors: Provide graceful error handling

​
Custom Functions

Best Practices:
  1. Keep Functions Simple: Break complex functions into smaller parts
  2. Validate Inputs: Check inputs before processing
  3. Return Early: Exit functions as soon as possible
  4. Document Logic: Include comments explaining complex logic
