Can I move vertices, edges, or faces similar to polygonal modeling?

Post by Moult »

In polygonal modeling tools, such as Blender, I can select a face of a cube, and move it in any direction. Similarly, I can select any edge or vertex and do the same. As I move it, I get real-time visual feedback of exactly what is happening to my shape.

In FreeCAD, if I draw a rectangle and extrude it using the "trim / extend tool", I get a visual feedback of the extrusion. Once that extrusion is done, I can change the "Dir.Z" data to change its extrusion length, but I am not aware of any "visual" way to change the extrusion length. Is there functionality similar to what I can do in polygonal modeling tools?
I also blog about 3D rendering, architecture, software and other on thinkMoult.com. RSS / Atom feed available for your convenience.

It is not possible when editing the properties directly, but if the tool provides an edit dialog, which usually is invoked by double clicking, then you often have a checkbox "Update view" which can be enabled.
Examples can be seen in Pad and Pocket operation.
A Sketcher Lecture with in-depth information is available in English, auf Deutsch, en français, en español.

As far as I can tell from Draft's code, these are called "trackers". It's a type of "preview" that is drawn using pivy.coin in the scene itself. But it's not native to FreeCAD; each tool has to implement its own tracker in the way that fits them.

This is what you are talking about: Freeform surface manipulation through interactive movement of nodes

Microelly has developed a ton of nifty features over the years; some of them are just prototypes while others become full features. The original threads are from 2017, but not much progress was made since. Now he's already looking into a node editor, which would also allow controlling such surfaces instead of picking on individual edges and faces.

I have the same pending issue for many months, in this point, I need to request help.

... I did not find a method to edit Vertex/Edges/Faces/Mesh/Solids Objects directly after use Draft WB Downgrade, I mean something like Blender.

... maybe is there any tool to convert Objects to others like Edges Objects to Draft WB Lines? this to create editable objects.

Edges can be converted to Wire with Upgrade but their XYZ vertex coordinates still can not be edited like Draft WB edit their Line Objects when I use double click, or maybe I did anything wrong?

As the wiki advises: it can be useful to use the command multiple times.

I tried, I just can use Transform or Placement, this move the entire Object, maybe I could rotate but If I wish to increase Lenght this is not useful

maybe converting this Edge/Wire Object to Draft-WB-Line/Wire-Object I could edit, but there is no way.

you could try to use the Tweak tool of the Design456_Workbench.

I am very impressed that SketchUp is being integrated in FreeCAD, sadly this WB just can edit Draft WB Objects. When I downgrade any object is already not possible edit anything
