Question about Linear Stoke Tolerance - PowerGEOPAK (SS4) 08.11.09.904 -

I'm pretty new to SS4 and have a problem with linear stroke tolerance.

I currently have the tolerances set in config as follows:

When I input a fieldbook, all tolerances work just fine.

Problem is, if I either do a "Create Terrain Model from Graphic Filter" or just simply add element to terrain model, it wont adhere to linear tolerances that are set?

How and where can the linear tolerance be set to new items added?  I've seen other post talk about making those changes in properties of elements, but to this point have not seen those options anywhere?

Below is example of adding an element:

Here it is added:

Linear stroke tolerance is not being applied?

Here are the properties of that line once added, no tolerance settings as discussed in other posts?

I have discovered I can use "Convert to Point List Linear Feature" on the features to either side of my GREEN line and then use "Join Linear Features" command.  Using this, the join command will utilize the linear stoke tolerances I have set.  Only problem with this, I have to click each individual line to covert to point list linear feature.  If I identify multiple elements to convert, it will only convert last element I had selected.  Is there a simpler method?  

Guess I ended with 2 questions here.  Any assistance would be greatly appreciated.

  • If you have a terrain that is generated from Survey and you want to change the stroking, then do this.

    Go to Workspace > Configuration and set the stroking to desired value.

    Close and reopen SS4 product.

    Right click on the Field Book and select Create Terrain Model to create a Terrain model with the modified stroking values.

    These two variables are used when generating 3d elements, a Survey Terrain, and the Apply Linear Template command. It looks like you are trying to add a 3D element that was created in the 3D model space. These variables will stroke a horizontal element with a profile in the 3D model. For example, if I create a Horizontal Element and assign it a Linear Profile, then select the 3D instance of this alignment, you can see that it strokes it every 10 units as I defined with the variable, and can change the default value to whatever I want.

    If your element is simply a 3D element, the stroking isn't available. If you want the stroking, In your case, I would set the Survey Linear Feature Definition that the element has to be included in the Terrain and set to Breakline. Here's an example. That way when you generate your terrain it is automatically added and dynamic.

      

    Another option would be to convert the 3D linestring to a 2D alignment with profile and Feature Definition using the Plan By 3D Element tool. Then you can control the stroking there.

  • I really appreciate your assistance Holly!  Again, I'm pretty new to SS4 from SS2 so its quite a change for me.  I work with survey data to create terrain models/tins.  Guess I'm just trying to figure out the most efficient work flow to combine 2 sets of survey data.  I realize there are quite a few ways and I haven't found an efficient one yet.  Our survey crews may be doing cross sections on an interstate highway system which could be 100 breaklines.  Between 2 days of work starting and stopping on an even section, we have link those together to complete the terrain.  I'd like to just use the "Join Linear Feature" command, but can't unless I go through every element individually and "Convert to Graphic Linear Feature" before that command works.  If I could select them all and do that with one shot it wouldn't be so bad, but haven't figured that out?  Using that command "Join Linear Feature", it will use the linear stoke tolerance that I have set in project level.  It just seems there is a more efficient way to do this?   I thought maybe I could just delete the whole terrain model, draw lines (3d) in between the 2 sets of data, then just run "Create Terrain Model by Graphic Filter" would solve my problem.  I found out that "Create Terrain Model by Graphic Filter" does not use my linear stroke tolerance settings, so fail. 

    Any assistance with efficient workflow would greatly appreciated.

  • What format is the data collected?

    We had to convince our crews that even when asked to "collect Cross Sections", that collecting breaklines and random points as thought they were collecting topography was easier on them and we could cut sections in such a way that it matched the points they shot. As long as they shot in the same direction or used JoinPoint commands when they had to shoot out of order, you would get automatic line work and a DTM based upon the feature codes.

  • We utilize Leica hardware and process via Infinity software.  Our Bentley input is a text file that has all feature codes and line strings already assigned by the crews, then processed through feature definitions (SMD in SS2).  Crews do a awesome job at continuing from previous day 100' down section with same codes.  Just haven't found the efficient way in SS4 to link different dumps together and still have linear stroke tolerance functioning as set forth.

  • Have you tried using the Append Point in Linear Feature command so that you don't have to convert your linestrings.
