Ujjwal not much to CAD in this plan of Climax delta. Only ribs are available and if you are constructing fuse as such then the firewalls are available. Rest you might have to plot every other part all afresh by physical measurement from the plan. The sheeting's, Side walls, Transom pieces, top and bottom braces of the wings, wing leading and trailing edges, control surfaces. Further to remove the pixels of grains pattern of balsa in every part is going to be a nightmare for DFX Conversion. Conversion to a DFX would be a project in itself. You can try that surely
For me building a single model scratch building is a much better option. as such the plan parts are very conducive for that. My main reason for picking up these plans was primarily because the plans were Conducive and flexible to even rearrange the inter-say distance of the ribs on a grid board.
Some progress.
Two sets of Ribs are out from the plan for cutting.
