I’ve been working on some construction projects (Metal, Wood) and still have trouble creating a descent technical drawing out of Rhino fast enough.
SO, I’ve been looking at other softwares 'approaches to this problem.
Currently, Rhino - sort of - uses the “AutoCAD approach”, by creating layouts and referencing certain parts in the 3D Model Area.
In order to create a descent drawing (with arrows, and text and welding signs), this requires me to heavily use the “MAKE2D” command. Then I need to apply hatches, which can be very tiring. The whole process is not much different from AutoCAD or a digital version of a drawing board. Also every change I make in the 3D Model will have to be done again. (Time consuming work) It takes more time to create a drawing than to model the object in most cases.
The result is, that the “Model Space” is now a Mix between 2D Drawings and 3D Modelling… (most put on different layers), but still a mix somehow.
Software packages like Inventor have a different approach.They strictly distinguish between 3D and 2D, even with two separate File formats. What they got right, in my opinion, is that these things are different and need to be treated differently. Drawing Files have lots of options to organize a drawing.(Filling header information semi automatic, welding symbols, etc.) Their drawing files import the model files. They can very easily create a section through a model and zoom-in on special areas. They apply hatches automatically using the right density of hatches so the drawing is “readable” when it’s printed out.
Since they are parametric Modelers, the drawing automatically adjusts to changes (which never works right).
SO HERE IS MY QUESTION:
Is the layout approach the right way? Would a stronger separation maybe be a good idea?
What is your opinion on this?
P.S.:My current workflow is as follows:
- Do my modelling all in Rhino (using scripts and all that great stuff)
- Export the relevant parts as separate 3DMFiles
- Import the whole thing into Inventor (of course no parametric intelligence)
- Create my technical drawing there (app. 10x faster than in Rhino)
- Export the drawing as PDF (or DWG file)
