![]() It is called 3D content-based search using sketches. If you want to search through some 3D models using a 2D sketch and keywords, have a look at Princeton 3D Model Search Engine. I did not have great results when trying this out, as it is ‘experimental’. In other words, you draw a small sketch of something, and then the search engine returns results that are similar to or related to that sketch.įirst I thought ‘quick, I better blog about this, before someone else does!’, but then I thought, ‘I better see if this exists yet…’Īnd, it does. I had this great idea this morning – why can’t we do a ‘search by sketch’ of images or other data? The Revit Kid.com!: Revit Tip – Export Rendered Images Without a Background Uncategorized image, layers, photoshop, png, rendering, tif, transparency No Comments Here is a link to the aforementioned PNG post: The TIF method is probably quicker and easier in most instances. Copy and paste these two images to separate layers in Photoshop.and one of them with Model Elements on (export this to PNG).one of them with Model Elements turned off (which will just show the background) – Export this to any format except PNG.Of course, you can also do this easily by: Now you can manipulate the model elements and the background separately. Use Magic Wand to pick everything that is ‘white’.When you export as TIF, you get a bonus Alpha channel that you can use to create a selection area and move the background to a new layer. In the spirit of one-up-man-ship, I recommend that you use TIF if you want to keep the background, but quickly separate it from the model elements. The Revit Kid demonstrated today that PNG files exported from a Revit render have no background.
