Problems with superelevation and shoulder rollover locks of my template

Akande, take a closer look at the constraints on the bottom of curb at the median. make sure the top of curb is constrained horz and vertical to the bottom of curb.

When fully superelevated where are the points of rotation? At the median edge?

Did you define separate supers for the left and right side of the highway?

Looks like the center of the highway could use a vector-offset constrained between the median curb and the outside curb if the center point slope follows the left and right side.

In Super, you would only need to create super lines for the outside and inside curb lines.

Could you attached your .itl and .ird file?

A few more things to consider.

Rollover locks are not needed in this case since there is no shoulder. The rollover locks are applied to the segment just outside your backbone. In this case you have curb, no rollover needed.

InRoads triangulation will not support vertical faces. So your face of curb component should have a horizontal offset from the bottom of curb to the top of curb of .01m or .001m. This is set to allow triangulation of the top surface. To check this, have your display triangulated surface checked on in your Roadway Designer Tools>Options.

Your bottom components points should be constrained Horizontally and Vertically to the point above. This is critical when applying superelevation. Your should also experiment with the vector-offset constraint. This is a very powerful constraint in a highway template with Superelevation.

The center points of your divided highway lanes, are they really needed? Not knowing your design I would consider removing them if they provide no value to your design. If they are in the template, to supports graphics in Microstation for a drafting line I would consider removing them. Parametric Constraints can be used to control pavement widths.

Bottom Line - Make your template simple as possible.

Joe thanks again for your quick response, here is the template library file and the roadway designer file, if you check out the superelevation image above you will see what i was talking about.

joe thanks i never knew that inroads cannot triangulate vertical faces i guess i still have alot of work to do, in terms of the template technologies. Thanks alot for all your expertise, Pls for the template file i attached look inside the AA TEMPLATES FOLDER and open the MAIN CORRIDOR TEMPLATE, this is the one i initially built as required by the design. other ones are just modification as i was looking for a possible solution.

Thanks Alot  Joe.

I fixed the Template in question by removing the CL points and changing the face of curb. I don't know how to send this to you because this forum does not allow e-mail addresses to be published.

I couldn't check the .ird because i need the .alg file as well.

In the Superelevation, are you using the table method or AASHTO?

For the Template I removed the center points L_CL AND R_CL and constrained the outside curb lines to the inside curblines with horizontal and slope. This will work as follows when defining the superelevation points. You will need to create 2 separate Superelevation entries. 1 for the left side and 1 for the right side.

NAME - Left Side of Highway

CROWNPOINT - L_EOP

LEFT  RANGE POINT- L_EOP1

RIGHT RANGE POINT - L_EOP

For the right side of the Highway

NAME - Right Side of Highway

CROWNPOINT - R_EOP

LEFT RANGE POINT - R_EOP

RIGHT RANGE POINT - R_EOP1

When finished you should see in your point controls for Super, 6 lines of Super

Joe.

Thanks joe pls could you attach the template file to your post with the built in attach file tool in the forum, so that i can have a look at the modifications that you have made to it. in super elevation i normally use the table method, because it is faster for me.  

Thanks once more

ok, attached is the file.

Thanks joe about to download and check it out, another thing have you heard of  dynamite vps used for road visualization, it is very powerfull, but it autodesk has bought it,  you can easily export your corridor into the program and it does all the visualization for you.

cheers

Regards

joe thanks alot i checked out the template it was amazing all the changes you made to it, it now worked properly with superelevations, Joe pls just one very important thing, pls have you ever used AUTOCAD with inroads, actually our design office is a multi cad environment, we are running inroads v8i SS2 on both microstation and Autocad, everything seems to be okay with microstation when i want to cut out plan and profile sheet, but when i try it with autocad there is an interuption and the command will terminate.

What am saying is, have you had any experience using autocad with inroads, most especially for plan and profile production

Thanks for all your endless advice and recommendations, i could not have  been able to get to the stage i am,

JOE THANKS

REGARDS

Thank You,

I have no background with InRoads and Autocad. You must contact Bentley Support for thier advice. If you are going to the BE Conference in Philadelphia, PA USA  you will gain alot of knowledge in these areas. I will be there.

Regards,

Joe

Thanks  alot Joe, i would really love to be at the BE conference, but due to the workload in the office, i cannot make it, i know it is going to be an exciting one for you, so please have a wonderful time over there in PA.

Once more thanks alot, you inspire me alot.
