Erich, With 3D (ArcScene, ArcGlobe), share your findings on �??Import�?? from Collada, especially, those from more complex 3D CAD plant models (oil/gas) and geomodels (geology). In fact, �??place�?? and �??replace�?? with COLLADA are also problematic. For the discussion, pls link to http://forums.arcgis.com/threads/93833-Any-limitation-on-the-model-replacement-in-ArcScene?p=333467&viewfull=1#post333467 So far, ESRI 3D team still investigating and no official reply. ++++++ However, what we have done with �??import�?? from COLLADA is through CityEngine 2012.1, which is OK for ArcGIS 10.x, including full-level details and textures. But, another issue with COLLADA (from CAD 3D models) is coming up. It looks that in ArcGIS 10.x / CityEngine, there is no way to 'geocode coordinates into those multipatch models (from CAD 3D models)'. Pls link to the idea at http://ideas.arcgis.com/ideaView?id=087E00000004v4aIAA Regards, ++++++ Worth to mention, the sizes of COLLADA from oil/gas and mining industries (3D plant models, 3D geomodels) are larger and complex, very commonly, 2~3 GB /DAE file. Honestly, it is challenging to handle properly. However, we believe that those issues in ArcGIS 3D have nothing to do with hardware in our practice, because the workstation used is one of the best business machines in the world, for example, 128~256 GB in memory, 2~4 processors /3.1~3.5 GHZ, 16~32 cores, latest /widely-used 3D graphic card and driver�?� ...

...  WGS84 but it still didnt work. This is also doesnt solve my problem as I have over 100 jp2 files to do. ...  v11.1 ecw plugin for ArcMap.... It seems that you are correct. On your description, an image with Geodetic /WGS 84 (lat/lon) is tested and exported into JP2 by ERDAS ER Mapper 2013. The output JP2 images from ER Mapper 2013 rotates and shifts within 10.0 SP 5, 10.1 SP1, and 10.2. Pls be realized with the following facts: [INDENT]*. JP2 with Geodetic/WGS 84 from ER Mapper 2013 is OK in ERDAS Imagine 2013; but has errors in ArcGIS 10.x and ENVI 5.0; *. JP2 with Geodetic/WGS84 from ER Mapper 2011 works in in ArcGIS 10.x and ENVI 5.0; *. JP2 with Geodetic/WGS84 from ERDAS Imagine 2013 works well in ArcGIS 10.x and ENVI 5.0; *. JP2 with UTM/WGS 84 or local datum from ER Mapper/ERDAS Imagine also works fine in ArcGIS 10.x and ENVI 5.0.[/INDENT] Generally, three things should be mentioned for consideration: First, it looks that ER Mapper 2013 could have bugs related to JP2, when it has Geodetic /wgs84 from ER Mapper 2013. Secondly, for the solution to massive JP2 generation in operation, it is good idea to use ERDAS Imagine (rather than ER Mapper). Also, advisable to test in other workstations, if ECW not accessable to ArcGIS in your machine. ++++++++++ By the way, not necessary to install the plug-in �??ECW for ArcGIS�?? to view ECW in ArcGIS (desktop). However, if loading ECW files into MD and then served as image services, it is good to install �??ECW for ArcGIS Server�??.

Ron, Share your observations�?� On our practice, when ArcGIS (raster layer property setting) comes to handle raster images for color enhancement and color-balancing, users are facing many challenges in operation. For example, not to be able to use good & effective image processing methods to adjust histogram, and then save into Lookup table, or threshold specific values for simple classification (and then save as feature class). It looks to us that it is also true to MD model & Image Analysis, even though color-correction functions/some adjustment methods were introduced starting with 10.0. Anyhow, we have been looking forward to seeing its improvements for a while ...

Hi, 1] What's the details which are lost ? I've stared at the CE/MP image for a minute, but am not sure what's missing.. Can you show the exact details ? Matt, Just investigate multipatch again and get the following findings: In CE, the model looks better, maybe in that �??Wireframe on Shaded/Textured�?? under �??Scene light�?? can be ON. Inversely, ArcScene has no similar capability (see the attachment and also compare with the previous). Obviousely, it indicates that CE has an advantage over ArcScene on its aspect. (So, it is Not a bug on exporting in CE)�?� ps. ... about 3d piping : post "CityEngine for Underground Infrastructure" http://ideas.arcgis.com/ideaList?c=09a300000004xET&category=Esri+CityEngine can you read this and maybe send me a few more inputs on this via PM? Let me know. Thanks, Already put a vote with my comment! (Sorry, what is PM :confused:). ... View more

CE should have some easy/flexible ‘component-based or model-based’ capabilities for more complex engineering designs, including facility and utility, in particular, like piping. Those components/models should be pre-defined and stored in the library catalogs, at least, which should be like some extensions for Trimble Sketchup (saying, 3Skeng at http://www.3skeng.com/en/3slibrary.htm). With ‘pure’ rulesets or ‘current’ design tools, it is very challenging for us to get those complex engineering designing/planning works done 'effectively' in CE … ... View more

I don't know much about AutoCAD. I was asked to translate a CAD drawing from UTM to MTM. Is it possible to do so without the intermediate step of creating shape files and exporting them back to CAD? I created a world file in ArcGIS (see below), but can the CAD user use that to translate his drawing? http://support.esri.com/es/knowledgebase/techarticles/detail/29039 thanks Mike, First of all, on my understanding, this process in ArcGIS makes no permanent change to the spatial location of the CAD file itself. Only the display of the data in ArcMap is changed. For permanent change, the solution to this 2D CAD conversion should have three steps in ArcGIS: import from CAD; project in FGDB; and then export the projected FC into CAD again. [INDENT]You are right, sometimes, the exported CAD via the mid-steps are not stable. Because of the different Scales between CAD and GIS, sometimes,  details of CAD datasets may be lost, including geometries/ textures/ attributes. In fact, we are working on conversion /projection of 3D DGN CAD in oil & gas into ESRI 3D and facing many challenges ... [/INDENT] Secondly, if not willing to go through the middle steps, (especially when final products are still CAD), you may use AutoCAD Map /3D, which help directly handle CAD data without intermeidate steps.

CE Team & Matt, Have you realized the following? [INDENT]1. When exporting the very fine model (imported from 3D CAD) into FGDB as multipatch, many details of the models are lost. See the attachments. What causes this issue? It looks to me that it is different from 3DS Max, which was posted at http://forums.arcgis.com/threads/59442-FBX-export-%28models%29-to-3DSMAX 2. As confirmed before, the model of trees also has an issue.

I have upgraded to 10.2 since originally posting this thread, and I am still encountering the same issues - I can't seem to generate any world files that don't have an x at the end, regardless of file format. I have georeferenced many maps in this series in 9.2, 9.3 and 10.0 and have come to know when to expect an approximate transformation and a world file ending in x, but beginning with 10.1, every single raster I georeference appears to save a world file as approximate. Is this expected behaviour or a known issue? Jordan, On my understanding, it is an expected AUX file(s), which store the transformation information between your raster and references, when updating raster (rather than warping). I guess, which AUX you get may rely on the raster format that you are working on... ++++++++ It looks to me that the release 10.1 & 10.2 have been improving the process (Update) a lot. In fact, the AUX file gives users very effective way to quickly update the accuracy of rasters 'as batch', where the AUX is only accessible using a product derived from the RDO/ERaster library, such as ArcGIS and ERDAS. Of course, still waiting for the algorithm 'directly & effectively' to be applied into MD very sooner.
