I have what may or may not be a unique challenge as a cross between 3d modeling and architecture but I could use some help. Two years ago I bought a house that I have done several substantial additions to. I went through the ?as built? routine to model the existing house and all the additions in another CAD program. Last year I transitioned to VW 11 plus upgrades. No problem. I am now running VW12.0.1. Now the challenge. The next phase of construction includes a watergarden/pond with waterfall grotto, stream, brick patio and more. All the landscaping design to date has been 2d. The pond grotto includes concrete block work, footings, brick work that ties into the existing structure so I am now extruding the 2d designs into 3d to plan out final elevations, depths etc. CRASH. The program locked up 18 times in one day with the addition of the 3d pond and other 3d elements, created as symbols. Because each depth of the pond has a different shape I created a closed polygon of each level of the pond and then extruded it to the proper depth. Each layer was then stacked and I tried solid addition to create one solid shape. Partially successful, some shapes would add together, others would not, lots of crashes. I have used what I have so far to perform live sections to attempt to detail the relationship of elevations of pond, footings, block-work and existing structure. At first I though the crashes where from overheating the CPU or overloading the memory and was about to upgrade but did a search of the forum and found stronger machines crashing also so I believe I have bad modeling making the program very unhappy. It also will not do a final quality render, which it would before. Now for the questions:
Are NURBS more effective in this application to create the curved shape, shell it and then use in renderings and sections?
Is there a way to run diagnostics on the drawing to find ?bad? spots that should be redone or deleted?
Any other similar crash problems that have been solved?
Any additional imparting of wisdom to be shared?
