Need advice on method of creating "hole" in 2D object while retaining the ability to edit...
Above is a photo of a work-in-progress landscape design I'm working on. I need help on creating the best method of handling the colored sections, a paver pool deck and the pool itself. Since landscape design is always subject to change, I created both objects as splines (joined with standard lines in appropriate areas like the steps). I needed to retain the ability to move curves around, which as far as I know is best done via a spline.
However, I simultaneously need three other things:
- A continuously-available ability to find the area of each object...
- Coherence between the two objects (keep the two lines creating the border as separate objects that are "tied together" such that moving one line moves the other)...
- The pool subtracted from the pool deck...
- In other words, the pool acting as it's own object, yet also acting as a "hole" in the area of the pool deck; the pool deck area should not include the pool itself (for area calculation and design purposes)...
So I need to be able to edit the pool and the pool deck separately, yet keep the border between the pool and pool deck aligned. Otherwise, If I need to edit the shape of the pool, I then need to edit the inner edge of the pool deck to realign the two while keeping them separate in terms of area calculation.
These conditions are possible if I do one the following (but I wonder if there's a much easier way):
- Convert each object (pool and pool deck) to a polyline...
- Convert each object to a region...
- Subtract the pool from the pool deck...
- Which allows me to find the area of the pool and the pool deck...
- Then undo everything in order to get back to an editable spline if changes are required...
-OR-
- Use BOUNDARY w/ island detection, select the pool deck...
- Make each object either a region or polyline (tends to be a region as AutoCAD says a polyline cannot be created)...
- Subtract pool from pool deck...
Now they are quasi-separate objects for which area can be found, but as regions/polylines the curves are not easily editable...
Any advice for a noob on this? Thanks!
