Hello, Been experiencing some learning difficulties trying to figure out the best way to model multiple excavations for structures on the same jobsite. The excavations would be within and around existing buildings of a wastewater treatment plant. I…

For some reason I'm having trouble getting my csv file to translate into a DTM model/TIN file. Yesterday it seemed to be working just fine, but no matter which avenue I'm taking it never seems to load correctly and I'm stuck without a TIN. What steps…

I noticed an issue with end conditions not tying into the existing ground line drawn in cross section cells. The problem occurred at several cross section and the error varied between 0.01' to upwards of 2'. After troubleshooting, it was noticed that…

Geopak_Support_2015_01_19.zip I have a dgn containing graphic triangles. When I create a new tin file using “Extract Graphic Triangles” I get different results when using Select Series 2 vs Select Series 3 Geopak. SS2 produces the correct resulting…

When doing terrain modelling of a proposed design in inroads, is it common practice to model all material layers below the final grade? Or you just model the final grade? What I am actually doing depends on the complexity of the model. For example,…

I am creating a TIN from survey info but I have several walls that are leaning, so when it builds the triangles it builds from the closest points so instead of goining from the ground points to the toe of the wall it goes to the top of the wall and visa…

I created a design surface from the Modeller but the dtm looks funny. the red line does not match to the component and is crooked. can anyone advise why this happens? and how can i avoid this? many thanks.

Background I am using MicroStation V8i w/ GEOPAK SS2. I obtained a ton of LiDAR data that covers about a 12-mile-by-2-mile area. The LiDAR data exclude all the surface waters (such as ponds, wetlands, rivers, and creeks) that are wider than 50 feet. The…

Hi all, I created a surface model by Corridor and Modeler on a highway interchange project. Now I am facing a rounding issues during creating sheets (Pavement Elevation Detail Sheets and Cross Sections Sheets) from this model. Apparentely, all the numbers…

Our second question on templates is in regards to end condition exceptions. In our backbone template, we have the edge of our pavement structure extending to the front slope of the ditch using the constraint "Vector-Offset" on two points (the edge…

Hi, I don't fully understand the option 'Draw Depressions Couterclockwise' under the Advanced tab in the View Contours box. Why and when should this be used? Jean Castro

We are new to Corridor Modeler/Roadway Designer in Geopak and have a few questions how to get things set up correctly. Our first issue is trying to use "if/then" statements on end conditions. Specifically, we want to test the slope between two points…

Wondering if anybody can help me out. I have two triangulated dtm surfaces for the exact same corridor and I want to identify which is the higher (in elevation) and automatically create shapes/polygons around the areas that area higher in one than the…

I created a corridor in SS3. I created terrain model from the corridor then exported the terrain model to a geopak tin. When I view the tin triangles (Using load dtm features) vs. the terrain model, the tin triangles are shifted. Does anyone…

Good morning Community, sometimes we've got problems with triangulation in InRoads in our company, it throws the message "Triangulation halted. ..." and I know that it's a known issue descriped in http://communities.bentley.com/products/road___site_design…

Hi peeps, This is my first thred and im in need of some help. Im doing my dissertation at university around DTM and have now got my self involved in Bentley microsation software. Ive installed GEOPAK so i have acess to DTM tool section. …

i have an existing surface (dtm) and i am putting in a proposed concrete pad at a certain elevation. i want the pad to tie into the existing ground at 2 to 1 how do i generate a new proposed surface showing the 2 to 1 slope .

Hello there! I have this issue, when i was done creating a surface (dtm) using Inroads, i wanted to view the low/high points of that surface, so is there any way to view them using InRoads??? Thanks & Regards, Imad Balich

All, I followed the steps in this video ( http://www.youtube.com/watch?v=8UON7jngtRU ) to create a terrain model from a corridor. However, the terrain model that was generated does not follow the surface of the corridor (see screenshot below - the…

I have the following data in ESRI shap file (.shp, .dbf) pipe data with up node, down node, up invert, down invert, diameter, shape man hole data with lid elevation, bottom invert and shaft diameter Can anyone help me with the steps to…

Hi volks, What if you have huge projects from a building site with lots of stages for earthworks and your client, a building company needs reports of lots of volume calculation for billing purposes. Lets say we have several surveys from the stages…

I have loaded and set the appropriate plugins but cannot get the contours to dynamically update after flipping triangles. Any help is much appreciated, Dale

Hi, I am having a problem with a large dtm derived from LiDAR data. It is about 350MB in size, and when I try to generate contours in either InRoads XM or v8i, I get an out of memory (swap device may be full) error. I was actually able…
