@Rich-O-Brien said in Softening a border edge:

The Soften Edges Panel will help you control the surface normals of a selected surface based on an angle threshold.

Thanks Rich, In this way you set the boundary condition of the angle treshold. I guess the question is more : what is the most efficient way to select certain edges of a (boundary) selection. Once they are selected you can do anything you want with them (in my case I want to soften them)

@Dave-R said in Softening a border edge:

Select all of the edges that you want to soften, right click on the selection, choose Soften. If needed, adjust the slider in the Soften Edges panel in the tray.

Thanks Dave! But that means I still need to select edges individually if its not already a curve (or already welded edges) I was hoping there was a plugin that could assist.

Hi everyone,
I’m currently brushing up on my SketchUp skills and working through the best way to efficiently soften border edges, often those that form a closed loop.

In cases where there are many edges, I’d like to avoid manually softening each one individually. Does anyone have tips, tools, or workflows that can speed this up?
Thanks!

What is the "correct order"? How is that determined?

Thanks very much Dave!!, I now realize that it is indeed a bit of a shady definition!
I just meant that each polygon has a begin and an end-point and the "correct" order is getting the sequential line segments in that order. So for example for a polyline consisting of 3 line segments I would get 4 co-ordinates in order that makes up the polyline:

x1,y1 start line segment a
x2,y2 end line segment a, start line segment b
x3,y3 end line segment b, start line segment c
x4,y4 end line segment c

I think this is the only way to rebuild a polyline if all you have are the co-ordinates.

Michiel

I have asked this question before but I guess its now somewhere on the bottom of the pile and I have not had a response yet Before I abandon this idea I would like to give it one more try:

I need to draw polygons (trace a scaled map) and export co-ordinates in the correct order to a csv.
I found this great plugin from TIG (Export Vertices to CSV), which works fine, except it dumps the coordinates not by following the line segment order. I am trying to read the generated point file into a python script that redraws the polygon for me... but I get quite a mess this way...

Thanks in advance!

Hi is there perhaps a way this plugin (or other) can export the co-ordinates of the polyline segments in the correct order? I am trying to reconstruct a polygon by loading in the co-ordinates from the csv, but I need them in the correct order. At the moment I am basically getting a point cloud

Thanks
Michiel

One possibility is to convert the original to Polyline, which will give you the sequence of control points. Indeed, make a copy of the original bezier curve before.

wow, I am honoured to get a response from the great Frodo himself!, you are a absolute hero just wanted to say that.

But I am not quite sure what you mean, because if I convert the bezier curve to a polyline (which I did) I just get a polyline....where are the control points ?

oops initial response too fast I got it now!, thanks very much!!

@dave r said:

Usually I approach it from the other direction and create identifiable location for the control points of the Bezier curve. Would that be possible in your case?

Thanks Dave!
That would not work in my case as I want to trace a shape (imported image) and then I trying to adjust set the control points to get the shape I need

@dave r said:

Are you still using SketchUp 2015 Make as your profile indicates?

Oh I need to update that, I am using Sketchup pro 2019

Does anybody know how to get the co-ordinates of the control points of a Bezier curve?
I am using Fredo6 BZ_Toolbar and I have been unable to figure it out
Any help / tips appreciated, perhaps I need another plugin (which?) but I really like this one

Thanks!

You can resize your object by 1000
then use CleanUp by Thomthom it finds many problems and repears
Then Joint PushPull by Fredo for give a thickness

Then solid Solver by Tig

But despit of that seems there are always problems, too little surfaces, maybe intersect faces etc...

where does this object come from? An unfolding one ?...

Thanks Piloe, its the result of an intersection with two solids from a topographic survey but its a complete mess. I just spend 3 hours to do it manually and finally managed to get a clean solid (joint push pull V) I guess there is no easy way when you get a shape like this

Better if you can send your skp (save as version 6) for a more large audience!

Thanks, I just uploaded the file.

Hello There !,
I am trying to extrude attached surface area into a solid to do some volume calculations (merge / subtract operations) But I am getting a lot of errors on the edges of my extruded shape. I am pretty sure it has to do with the fact that the border edges are broken into segments whilst there are no triangulation lines. How can Sketchup still generate a surface area and how do I get rid of this (without doing it manually?) and generate a proper surface to extrude?
Thanks

Does anybody know of a way to have two extrusion paths through several 2D areas?
I have been using Curviloft a lot to extrude 2D shapes over a single path but now I am getting into a particular problem I dont know how to solve (except manually which will cost me too much time)

@dave r said:

The file you upload has all the X-cross components exploded. If you leave the components unexploded you should be able to edit the component, put a guide point at the intersection and erase the lines. Then explode all instances of the component to leave yourself with a cloud of guidepoints.

I was going to make an example using your model but at this point it would be very time consuming to put the components back.

Thanks Dave, I exploded them because I thought it would be easier to work with most plugins. But are you suggesting I do this manually ?, there are thousands of points

Hello, I have an issue with importing an autocad file with (xyz) points in separate layers. Each point is imported as a separate group consisting of a "X-cross", so when I explode the points I am left with 4 lines per point. What I need is a singular guide point for each crossing so I can triangulate the layers.

I have found some plugins that can forexample convert each end point to a guid but thats not a very nice solution. Does anybody know a plugin that can actually provide a guide point for each point where lines are crossing? Or any other solution would be great.

Doing it manually is not an option as there are way too many, I have attached my file

Thanks for your help

I was a bit fast posting this, but maybe for others having the same problem
I just found the plugin I need: its ThomThom Guide Tools

It has an option CPoint at Edge-Edge Intersection (v1.2.0) Adds a construction point where the selected edges connects. Note: only "loose" edges - edges that is not part of a face.

Great !, what should we do without ThomThom!
