Revodesign problem

[dean]

Why can’t I reverse engineer almost 99% of stl files that I download from printables for example
file

1. fit line, slot, circle,… doesn’t work
2. strange (unclear) stl when I open it
   The same thing happens if I draw something in QS and export to stl and then open the same stl in QS (same for stl exported from solidworks)
   the more technically undemanding the object is, the worse the results
   Is this because of the trial version or is it the same in the purchased version??

Hi dean,

Your post is a little vague. It sounds like you are trying to modify an stl file in QuickSurface. What version are you using (lite, full, sw plugin)?

Have you watched any of the tutorial videos? It sounds like you are trying to do things in the wrong way, but I cant tell from your description. Just saying “doesn’t work” isn’t a lot to go off of. Most of the time it is just user error…

Hi

1. → I guess your approach might be wrong, as Nickluvin says → Check the tutorials , Revodesign is Quicksurface lite, so you should go through QS tutorials.

2. right-Click on the Mesh in the Tree and activate “Flat shaded”. This is example with the same mesh with it turned on and off.

fit line, slot, circle,… doesn’t work
with stl from scanner everything works fine
The problem is with stl files exported from a cad program

The trial has expired and I can no longer test it.

I think the problem is due to the density (too few) of “white” dots

I see your cross section, but how are you going about fitting lines. You are not showing that work flow.

I opened the part in RevoDesign and I think I see the issue you are having. you go to create a sketch, and it shows up that it should create a good sketch

At least for me, when I go to create the sketch, it is missing a lot of data. Which tells me it is an issue with the stl file.

I re-polygonized at 0.02mm and ended up with something missing some faces

but now when I do a cross section sketch I get something a little more usable

Performing actions like fitting circles is working

Why there is missing data in the sketch you go to edit it I am not sure. To be honest though I think you are going to struggle to create this part in RevoDesign because of the lack of “cutting” tools you have available to you. You cant trim surfaces, do boolean cut/combine/intersect. You have no fillets. This instance of the program is more for simple fixing of meshes and orienting your mesh.

You need to look into the pro version of QS or another cad program if you want to do a deeper dive into Reverse Engineering. Fusion 360 is a popular lower cost alternative to look at. @ivan has some good tutorials on doing this.

I was looking at it a little more. What I think is actually happening is it is showing nodes or points because it is perfectly straight between those sections.

You can get a line to go by selecting 3 points

Similarly I can get arcs and circles to work this way

even though its not continuous data, you can fit lines, arcs, and rectangles
