Looking For Help? / Re: measuring volume

you can use the AREA command, which asks for points to be seton the perimeter of the shape
or , if it is a poly line ( a line comprised of multiple points) you can select it and open the INFO box. at the bottom of the box there is an option to display area of selected entity.

edit, just read the post asks about Volume. I'm not sure what the question is now

If I create or import an irregular 2d shape is there a way to measure the area of it?
Looking For Help? / Double line point relative
« Last post by Ado on June 06, 2017, 04:30:38 PM »
When I make an arc and convert it to a double line (with or without end caps)how can I get a point relative on the new line?
I'm new to this so sorry if ti's a simple question.
SDK Errata / DragSelect
« Last post by bdeck on June 02, 2017, 09:50:48 AM »
From the example for DragSelect in SDK v 17:

>SelectMode3D  should be ">3DSelectMode" or ">2DSelectMode"
<Type t

Errors and Omissions in documentation:

1) ">SelectMode3D" is not a valid function. Should read ">3DSelectMode" or ">2DSelectMode"

When Not in point select mode Or When No entities are currently selected:

2) When t=0 or t=1, DragSelect selects any entity fully inside the box, even if it touches the box. A line coinciding with the box edge IS  selected.
3) When t=2 or t=3, DragSelect selects any entity at least partially inside the box, but not if it only touches the the box. A line coinciding with the box edge is NOT selected.

Maybe use SetWorkingPlane to temporarily rotate the coordinate axes, and then use dragselect? Calculating the new position of the bounding box would then require some mathematics, but it sounds like you're up to it. Then use ResetWorkingPlane when you're done.

You could consider temporarily rotating your entire drawing, and then using a normal selection box?

Hello everyone,

for one of my macros I need to be able to select entities using a selection box at an arbitrary angle...  ::)  I was thinking about this for a long time, because >DragSelect obviously can't just be rotated.

The solution I came up with works for about half the cases I need the angled selection box. Basically, I'm using a series of complicated SIN() and COS() calculations after a quick >AngleDistance to calculate the four corner points of the angled selection box, then I run >PolygonSelection and pass it the four corner points.

This works fine if I want to get a similar behaviour to "Type 0" of >DragSelect, which only selects entities which are inside the selection box entirely. But if I want to select any entity touching the angled selection box, >PolygonSelection leaves me hanging.

Currently I don't see an easy way around this, but it could easily be fixed if the >PolygonSelection command offered you these "Types" of different selections as well, with one type being "select only items inside or touched by box".

Correct, we finally added that control in the 2D version starting with V24.

Fortunately, the sys(1173) trick works in almost all versions since we implemented the CS display (circa v18 or 19, I think)

I'm using 2116 Max and it is there both in 2D and 3D. I just check V23 Max and it is there also. I don't have the 2D only. Seems as thought it was introduced about the time of v20 or so and as you say not in the 2D only program.

Lar, I think that's only available in the 3D version, I'm using DC 23 2D.
