Hi there thanks for posting in the community! Lucidscale can draw lines between resources that explicitly reference another in the metadata: 

• Elastic Load Balancers (ELBs) to Auto Scaling Groups (ASGs) [ELB→ ASG]
• ELBs to EC2 instances [ELB → EC2]
• CloudFront Distributions to S3 Buckets [CloudFront → S3]
• Application Load Balancers (ALBs) to EC2 [ALB → EC2]
• VPC Peering Connections 
• Route 53 Hosted Zones to ELBs S3 Buckets and CloudFront Distributions [Route 53 Hosted Zones → ELBs S3 CloudFront]
• Transit Gateway to Peered Transit Gateway and Virtual Private Cloud (VPC) attachments [Transit Gateways → Transit Gateways VPCs]
• Route Table to Internet Gateways and NAT Gateways [Route table → Internet Gateways NAT Gateways]
• API Gateway to Lambda [API Gateway → Lambda]
• VPN Connections via Transit gateway [Transit Gateway →  VPN Connection → Customer Gateway]
• VPN Connections via VPN gateway  [VPN Gateway →  VPN Connection →  Customer Gateway]
• HostedZones → ALBs

Note: If you’ve summarized resources within a Lucidscale View you will need to un-summarize them in order for your lines to be rendered in the model.
