data inspector is not displaying geometries correctly

FME Information Edition: FME ESRI Edition (node locked-crc) Version: FME(R) 2017.1.0.0 (20170731 - Build 17539 - WIN32)Operating System: Microsoft Windows 7 64-bit Service Pack 1 (Build 7601)When I inspect geometries and zoom in, the data inspector does not render them correctly (see screen shot - the line should become focused and not fuzzy). In order to display them correctly I have to change to Table view and then back to 2D Geometry view. Can I do anything to resolve this?I have tried it with a single polyline and with 10000 Points - the result is the same.

Schema mapper attribute range

Is there a way for the schema mapper to map based on a range of attribute values? Essentially MinHeight, MaxHeight, NewValue 0,10,Level1 10,20, Level2 20,30,Level3 such that a feature with a height of 14.7 would map to Level2. The mapping file is an external csv maintained by someone who has no knowledge of FME, and get's updated on avergae every 2 months.

Managing shapefile attachments

I have a client with an interesting request. Basically they have about a dozen shapefiles that consist of points, and all points have 1-4 attachments. What they'd like is to combine the shapefiles into one complete shapefile, and carry over the attachments as well. Unfortunately ESRI doesn't allow you to merge shapefiles, and have the attachments go with it. To further complicate it a bit, all the attachments are labeled the same: photo01, photo02, photo03, or photo04. The naming convention is generic, so simply extracting the photos and reattaching them after merging the shapefiles is out of the question, unless I somehow rename the attachments as I take them off and link them to their proper attributes as they get reattached to the merged file.I very well could save each attachment and rename it with some kind of naming convention as i download it, but it's repetitive and mind-numbing, and it seems like a perfect candidate for automation. Anyone have any thoughts? I'm

finding duplicates then selecting one based on a value in another attribute

I have 3 attributes that could potentially have duplicates. A, B, C. After finding the duplicates, I have to make a decision on which ones to keep based on attribute D. The scenario is as followed: if A,B,C are the same, take the record where D is not null. If D is null for both records, take any one. If D both have values, take both unless the value in D is the same then take just one. Help!

Point elevation from 3D polyline

Hi,I have a set of 2D points and a disolved polyline in 3D formate that they overlap (with 100% precision) If the elevation (Z coordinates) of the polyline is removed. I am looking for a solution to elevate the points such that the intersection of each point matches the 3D polyline.Best regards

Limit vertices but maintain general polygon shape

I need to take a polygon feature and create a csv with all the vertices. I have the whole process and it works no problem, except that the amount of vertices has to be limited to 50. I have some very detailed polygons, particularly at coastlines, that become self-intersecting after passing through a vertex limiter. So far, my process involves a donut hole extractor (process that ingests the csv cannot handle multi-part polygons or holes) and the outershell passes into a vertex limiter (vertex limit:50, aggressiveness level:.001) and then after passing through a geometry validator, the rest of the process creates the csv.What I need is a small final file, but as much accuracy as possible. I am aware that limiting the vertices from thousands to 50 will create angular polygons, but what I want most is to maintain shared boundaries while still limiting the vertices. I do not want them to overlap, have gaps or self-intersect. I have tried the generalizer, but I have a specific number of ver

Merge or filter points that have a common attribute value and are spatially close

I have a couple of thousand points that have a number as attribute. Some of those points are- close to each other - also have the same number Note: there are also points that have the same number but are far apart. I want to merge all points that match both conditions into 1 point So far I have set a neighbourfinder transformer, which groups the points by number and then finds the closest points (max 4). But how do I merge the resulting related points into 1?Any suggestions are welcome. Kind regards,Pim Verver

DWG - open, transform, write - layout (paper space) issue

Hi,I'm using FME 2016. My workflow is:- open dwg- transform (coordinates)- write dwgWith FME 2016 I'm able to retain layouts but here is my problem: layout viewports don't seem to be transformed. After the coordinate transformation is done the viewports still point to where the data was before the transformation. I enabled "read paper space layout Information" and "read model space entities through viewport".Does anyone know if transformer works an viewports as well and if so, how?Thank you, Rob

I can draw lines on a raster and then save as a jpg. Why can't I put text on the raster and convert to jpg too?

I wish to add text record of attributes to jpgs. I am creating a workspace runner to do this. However, I cannot get the text to be applied to the raster. I can see that the text is created in Inspector, but Vector on Raster overlayer does not write the text to the new raster. (See workspace)I tried mapnikrasterizer with even less success; I couldn't get any product from the jpg writer.This seems like it should be a simple fix.Your help is much appreciated,William

XRef in DWG from template

Dear users of FME,The main question is short and of the kind 'yes/no': When writing to a .dwg file (creating a new one), using an existing template .dwg, is it possible for the external references from the template to be incorporated in the new .dwg? Especially when making use of relative pathways in the external references? Also, would it be possible to create attributes like 'autocad_xref_path' and 'autocad_xref_name' to manually specify an external reference when writing to a new .dwg? I have been trying out both cases but none seem to work. Looking forward to your opinions!

"Bad Allocation" error using MapnikRasterizer?

Hi guys,Has anybody else run into an issue using the MapnikRasterizer where the translation terminates unexpectedly with the error "Bad Allocation"? My first thought was RAM, but I'm running 64bit FME 2015.1.2 with plenty of available disk space and physical RAM (10+GB free at the time of the error) so I doubt it is that.I am trying to rasterise Ordnance Survey Mastermap data using the EPSG:3857 Bing Maps grid. The error seems to occur randomly, and frustratingly kills the whole process so no images are written to the file system (although multiple tiles do pass out of the MapnikRasterizer before the issue occurs).Any help greatly appreciated!

Clipping 3D contour lines with multiple regions

Hi all,I'm pretty new to this and don't have a very good idea of what things are possible using FME. I'll try to describe what I want to do below.I have a big dataset(.shp) containing 3D contour lines of New York City and I have another dataset containing 2d polygons representing neighborhoods in NYC.I want to clip the contour lines within each region and save it separately to a dwg file. So the result would be multiple dwg files, each containing a 2d polygon and only contour lines withing that polygon. I tried exporting all to one dwg file but it results in a very big file that autocad cannot handle opening. Any ideas?
