Looking For Help? / Re: small cursor in stretch command
« Last post by Lar on August 03, 2017, 05:03:09 AM »
Rccon,

In 3D mode the Stretch command works completely differently depending on whether the 'use 3-d box' is enabled or not.

If disabled you get the small cursor you described but you can press F5 to get the cursor across the full window.

HOWEVER, if you use multiple windows you should set all you points in an orthographic view (Top, Front or Side)... BUT be careful about snapping to existing points that appear on top of other points because it's hard to know which point dcad will snap to. What I'm saying is you may want to set the first two points in an orho window then set the last 2 in a 3d window (to make sure snap to the correct point - usually for point 3)... but dcad will consider all 4 points as if they were all set in the last window used... so although you were setting the 2D rubber band box for the first 2 points in the ortho window, dcad will consider the points within the rubber band box as it visually appears in the window you set the 4th point in. So, in this scenario, even if you do snap the 3rd point in the 3D window just set the last point in the same window as the first 2.

If 'use 3-d box' is enabled you will get the 3D cursor (and F5 will make it fill across the full window). Now, the first 2 points-to-be-set has to capture all the points-to-be-moved in a 3D rubber band box. So, it doesn't matter which windows the points are set in but you may need 2 ortho windows (Top and Front-or-Side) and a 3D window to visually confirm the 3d rubber band box encompasses all the points-to-be-moved.

Lar
ps:
1] F5 is a toggle so it flips between a cursor that fills the window and one that doesn't.
2] The Stretch command completely ignores Ortho Mode (H).
3] If using the method described by Phil above remember that certain Elements won't get move, such as dimensions and multi-lne text.

I see the drawing in question has 14,000 or so pints, and thus the resulting solid with holes would end up having about that many!!!

That may explain why it wasn't working.

Solution - draw cylinders with fewer facets

I have seen similar problems many times.

I create separate solids for each hole - usually just cylinders.

Then I select all of the hole solids and use Solid Define to make one solid of them all.

Then I select this combination solid from the "plate" and it works unless the 5000 point limit is reached. Unfortunately, it often is exceeded.

You can also "stretch" objects using Point Select mode - "CTRL 1" toggles Point Selection Mode on/off.

1. Select the object or objects to be stretched. All points will be marhed with small pen squares.

2. Select the points to be moved - the selected points will be marked with snall black squares.

3. Click on one of the selected points - this will be the movement handle.

4. Move the cursor the desired distance and angle and the selected points will follow.

5. Click to set the selected "handle" point where you want it. All other selected points will move to new positions relative to the movement handle point.

Are you running in RED mode or standard?  RED might reduce cursor jumpiness.

Do you have running snap enabled?  If so cursor will always jump to nearest snap point, try turning it off.

Cursor should move smoothly while setting points for the stretch, and it should display the 3D cursor and a selection box.

Using dcad 2017, bu I've had this in earlier versions, too. I'm somewhat 3d challenged so 3d selection box doesn't work for me. With 2d selection box and a fairly simple drawing I can select the points I want without by a box in the plane of the screen however near or distant they may be, but the cursor is so small and jumpy I can hardly tell where it is.

Even that may not work every time. Remember, for about 12 or 13 versions now, when you make a hole in a plane, the result is still a single plane (used to split the plane into two pieces). With a lot of holes, that can lead to a lot of points around the plane's perimeter, and you might find yourself approaching the 5,000 point limit.

Possibly converting the platesolid to a solid surface before subtraction may help.

Also, you asked about drawing info (and selection filter) only showing grids and planes, no solids. A solid is not an entity type, it's essentially a special kind of group. Just as every object with the same group id is in the same group, every object with the same solid id is in the same solid.

*addendum* After creating the top plane for the platesolid and re-defining the platesolid to include the new plane, I converted the platesolid to a solidsurface entity. Then the subtraction seemed ok.

I started working on this, and I was able to get a subtraction, but it only penetrated to top surface.

Then I had to go buy some food, so I never finished the job......

Definitely something weird here, why would grouping the objects affect the outcome?

Found the problem.
Did the same procedure again, but without grouping anything at any time.

1  Selected all 2d hole patterns and executed make plane. Result = discrete planes.
2  Selected all hole planes and executed extrude. Result = discrete extrusions.
3  Selected all hole extrusions and executed solid define. Result = single solid.
4  Subtracted it from platesolid. Worked perfectly ( but took some time ).

When I issue the stretch command, I get a dialog in which I can check "use 3D selection box.

Then I get a 3D cursor and a rubber band box showing the selection.

What version are you using, in case that makes a difference?
