Workset Posts Summary

Penggunaan workset membolehkan satu pasukan bekerja pada satu fail dalam satu masa secara kolaborasi. Tetapi pengguaannya boleh dikatakan kompleks. Disini Revit OpEd telah menyenaraikan Isu-isu mengenai penggunaan workset:

Webinar: Performance Based Design - The Energy Modeling Process

Reduce Precision of AutoCAD file for insertion into Revit (too many decimals!) and it has some wacky or imprecise units (like the distance between two walls is 8250.092234897). What you need to do is reduce the precision, such that all the decimal points get 'chopped off'. To do this: Open the offending DWG in AutoCAD. 'Save As' and choose a DXF format. Go to Tools menu - Options (see below) Choose DXF Options, ASCII Format and set the 'Decimal Places of Accuracy' to the desired value (choosing 0 will remove all decimal places): Hit Save. I recommend that you now open the DXF file you saved, and then resave it as a DWG file. Now you can insert your file into Revit, and you won't have to deal with imprecise units. Please note that this process may result in some 'rounding off' of values - you may want to double check the resulting file.

Let's say you have AutoCAD file of unknown origin, and it has some wacky or imprecise units (like the distance between two walls is 8250.092234897). What you need to do is reduce the precision, such that all the decimal points get 'chopped off'....

Just How Accurate is 123D Catch?


Do you remember Autodesk Lab's Project PhotoFly? Well, it has recently graduated into 123D Catch. And it's still free!
The idea behind it is that you can use a digital camera to take pictures of something, load it into this software, and it uses all sorts of black magic and cloud computing to convert these pictures into a real honest to goodness 3D mesh with texture. I used the Labs version to take pictures of a small statue on a co-worker's desk using just the camera on my cell phone and the results were astonishing. You can then take a known dimension on the object to convert it into something that has real size and scale.
But just how accurate is the resulting model? A model generated from nothing more than digital photos.
Well, to help answer that question I thought I'd pass along an article that I recently ran across:

Using Photofly with Revit and Vasari


Using Photofly with Revit and Vasari

So first lest start with what Photofly is: It is basically the merging of point clouds and photogrammetry. What it does is take a set of photographs of a building and stitches them together in 3D space and figures out the camera locations for each image. Once it does that, it can be used to create a 3D model of the building that is usually accurate enough for basic conceptual design and analysis related to sustainability and engineering. The heavy processing for all of this is done in the cloud and what you install is a small application to view and edit the results of Photofly. You can output the results to a number of file formats that could then be imported into AutoCADRevitVasari3ds Max among others.
