HOW TO CHANGE ELEVATION VALUES OF REFERENCE POINTS BY INSTANCE PROPERTIES/OTHER?

Hey BIMMERS !! 

 

I have a situation here.

 

Objectives :

 

I wanna change the elevation value of the reference points contained on this spline through points to gradually meet (slope towards) one of the edges of the mass, seen in the picture below, while maintaining the curvature of the said projected spline. (breathe)

 

Problem :

 

When I click on the point, there is no elevation property in the instance properties panel where I can type in the elevation, it only gives me handles to drag the point, which kinda defeats the hope of any accuracy. 

 

Any suggestions ? Many thanks

Switch to an elevation view and you can enter the relative dimension from
the reference point to the associated work plane.

  • select the point.
  • be sure that the Host is a Level
  • use Offset to control Z distance from the Level

if you want to have some predefined Z ( heights) you can make an Offset Parameter

I unmarked my post as a solution.  @constantin.stroescu method is more legitimate for changing Reference point coordinates.  Mine is kind of work but it is more for vertex points from a form, where you do not have the Offset parameter from their properties.

In general, I think it would be good to wait until the user who posted the question marks the solution, especially when there are several valid responses to the same question. I have noticed a tendency to mark solutions too quickly. I think waiting some time would be better. If nothing is marked yet after a few days, then it makes sense to go ahead and mark the solution, after allowing some time to evaluate all the replies.

OP marked the solutions in this thread.

 

I have never marked my replies as solutions, ever.  I do mark other replies as solutions if they are obvious AND OPs drop the ball after at least s few days.

@Alfredo_Medina 

 

You are quite right. I will take care not to mark the question as resolved quite so quickly.  

 

The fact that someone may reply within a few days with a thorough solution, and also problems that can occur after having tried those solutions

are reasons enough to make me wait before giving into the happy temptation of hitting the RESOLVED button the next time round.  

 

LEARNING IS A SLOW PROCESS. Thanks for the advice.

 

... (the next challenge I´m facing):

 

Having disclosed that... (please don´t kill me just yet Smiley (überglücklich)) I have had a hiccup trying to change the Z value of some points. 

 

Upon selecting points, the gizmo handles are not perpendicuar to floor levels. 

 

When I modify the offset, as the Z-axis is rotated, the point moves out of place in plan view. 

 

I can see that in the Instance Properties I can change the Rotation Angle, but I don´t know what angle it is currently in to be able to set it to universal USC. 

 

Would you be able to help me with this? Thanks

I think the problem that you are experiencing is due to using a sequence of steps that is not good if you plan to use the reference points to manipulte the shape. What you should do is:

 

  • Create all the reference points that are going to drive the shape, on the reference level. They are hosted initially by the reference level, and therefore, they have an offset parameter.
  • Optionally, you may need to host new points on the initial set of points that are on the ground.
  • Then, create splines using the points that you have created.
  • Then, create surfaces using the splines that you have created.
  • Now, if you change the offset values of the points, you can control the shape of the surfaces.

Hello again  @Alfredo_Medina ! 

 

I tried your suggestion to ´´Create all the reference points that are going to drive the shape, on the reference level´´. 

 

This allowed me to change the Z offset as desired. Now my model is resolved Smiley (fröhlich) Thank you, Thank you !! 

 

Thank you to @ToanDN and @constantin.stroescu as well for sharing your knowledge with me and others that find themselves with this hurdle !  

 

Side note: 

 

Building roads in Revit alone was an arduous challenge for me, despite having watched Marcelo´s Sgambelluri´s videos on handling topo.

 

I found this post that uses Dynamo to drive the modelling process of highways, which seems more user-friendly.

Though I haven´t tried this method yet. 

 

How do you model roads and topo in Revit ?
