Looking For Help? / Can DC output an SVG file?
« Last post by pnb on Today at 12:26:58 PM »
We have a nice A3 printer but it reads SVG files.
Can DC provide these? At the moment I am printing drawings as a pdf and then converting them on line.

Yes, I think I can understand your concern. As a I get to use and learn more of the 3D version of DC, I have left behind lots of 'failed' points in my drawings, as you have identified. If they become important when the file is used to make something surely there should be an automated way of removing them, I guess even experienced users will leave some?

I hoped after all the coaching I would be able to complete my project by myself. No such luck. Perhaps rogue points are the cause of my current problem with the attached.
If I extrude the complex 'roundish shape' in the panel with z = -18 the shape is perfect but extrude the wrong way, out of the plane. If it is extruded with z=18, the way it needs to go, the result looks like 'a ball of wool' within the correct outline!
What on earth have I done wrong?

I do have a concern about making a pointmark or any other line or whatever to a solid, especially by incorporating it into the solid with Solid Define.

If you do this I would suggest placing these reference marks on a separate layer so the display of these things can be turned off. I do know that lines display very bright in shaded images. If you plan on generating images from your 3D drawings you should make an effort to purge lines from them, or at least place them all on a a layer that can be disabled.

My real concern is what effects these things might have for future uses of the solids. I do not know what 3D printer drivers will do with the zero and one dimensional objects. I'm not sure what effect, if any, they will have on the solid Boolean operations.

Thanks again both of you. You must have amassed many hours with DC 3D to be so well versed in its method and idiosyncrasies!

Phil, yes 2D Cover was my poor description of a circle over solid cylinder, or similar. As constructed solids seem to retain redundant construction points it would be nice if it could also retain specific handles, ones that can be used for future use. I was just hoping!
"Display CS" was exactly what I wanted.
I will try the alternative shading 'systems', if I can, the screen corruption of its setting window with my screen res' makes any changes a bit hit and miss.
The vc.d3m macro sounds very useful, I will explore it.
Rob; Setting a point mark on a solid seems a good practice, I will try to remember to add one when I am drawing.

Onwards and upwards!

By 2D cover, I think you mean the drawing of a circle to establish the centre of a cylinder's face?

Another example - 2D diagonal lines can also be used to find the centre of a rectangular face of a solid, by snapping to its mid-point, as you might also do for a 2D rectangle.

As such temporary construction lines as I like to call them have lots of different uses to find points that don't already exist on whatever shape you are working with.

Even though you cannot reliably establish a permanent handle, you can draw a pointmark where you want it, (erase any construction lines you drew to locate it) and include the pointmark in the solid define command.    Subsequently, if you right-click on this pointmark your solid will be selected with its handle at that point.

OPen-GL shading option is selected in the upper window of the shading dialog where it defaults to GDI.   The only problem with working in open-GL shaded mode is that for most people (depending on video hardware) any rubber band lines you produce while drawing will be excruciatingly slow.

Let us know how it works for you.

I have no idea what you mean by "new 2D 'cover."

To see the XYZ directions open "Options/Options/Grid" tab and check the "Display CS" option. This will cause the three axis orientation symbol (CS) to be displayed in the working window.

In theory, if you select "Enable sticky handles" in the "options/Options/General" tab, a permanent handle will be created for an object. However, it doesn't work with all commands (bug), so this is pretty much useless. There really isn't any way to set a permanent handle to be used by all commands.

What do you mean by "keeping the shading" when changing the view center? With all GDI shading, anything that causes the display to redraw will cause the view to change to wireframe. If you use OpenGL Quick or Gouraud shading it will remain after causing the screen to redraw.

For what it is worth, I have found the necessity to set a view center and then changing the view angle annoying. I have reassigned the "Y" key to use the vc.d3m macro. You gravity snap to any point on the drawing (or just left click on the screen) and the macro sets the View Center to the snap point and then starts the "Set View by View Center" to orbit the view about the new View Center. Common sense tells you that this is the way the "Set View" function should have worked in the first place!

Thanks, I see it now, I can move parts of the plate by themselves! Not sure how it became exploded, too many failed attempts at doing what I wanted perhaps. There seems to be a lot forward planning needed to get the desired result.
Some questions please.
Is it possible to:
Make a handle on a solid at a specific place without make a new 2D 'cover'?
Can a handle remain with an object for its life and so make it re-usable?
Is there a way of displaying the x y and z directions in the working view?
Keeping the shading when changing the view centre of an object?

Once again, thanks so much for walking me through this part of my project.
Only 3 more panels to do, I will try not to bother you again!

For some reason, the plate solid got exploded and is missing its top surface in your latest drawing, so the tool wont subtract.

I pasted your latest tool into the previous plate drawing (using one of the corners as a handle) and it subtracted fine with results as below.

That version of the plate does show a lot of the extraneous points we were working on previously.

Thanks for persevering Rob.
I think I must have missed the 'make a plane' step.
I have had another go and this time DC refuses to subtract my punch from my surface. Both seem to be solids so a bit puzzled.
I would welcome your diagnosis.

To answer your question as I understand it, the following should do it:

Draw another 3-point circle around the bottom end of the centre drill hole.  (Blue)

Then draw a 4-mm line down from the centre of that circle.   (Red)

Use the bottom of that line to set your handle?

Now looking at your tool drawing a bit further, I noticed the large circle and the centre hole are both hollow, so they will not remove any volume when subtracting.   I am not quite sure what you intend to achieve there.
