scale function

[Anonymous]

I am new in dynamic block and I am trying to make a double door with frames.
But I cannot seem to succeed in scaling the arcs with the right scale factor
and the right basepoint. Can anyone help me please?

Good use of Stretch Action for a newbie. You are learning well. Naming of the parameter is smart but carry that to the actions too so that you know what actions affects what geometry. Save the DB within your container drawing for use here and so that you can test w/o having to insert into another dwg.
Your Scale Actions are fine and working properly. The trouble is the multiplier for Stretch2. It needs to be .5 since both doors are being stretched. This way each door gets half the total width.
The Flip Action needs to include the Stretch2 Action (door width) to work properly when flipped.
Also, I moved the Door Width Parameter to the center points of the arcs which allows them to scale from center and not offset to that. Notice that the grip can be moved where you need it regardless of Parameter ends. Try moving these parameter points and see how it affects the arc. It's not that the arc is scaling wrong its that the offset from the center of the arc to the parameter is scaling also; therefore moving the center of the arc.

Thank you very much Charles for your help and your
good word.

I prefer of course the door width to include the
frames, but this is much better than nothing...

I don't believe that there is no way to make it
work like that. Dynamic block is so magic, so I think there is nothing it cannot
do!

Never mind... Now that I look I see what you mean.
I think its possible and will give it a try later if Juris does not beat me to it!

Haha! OK.

I am attaching a great achiement of mine for you to
see.... I am very proud of it. It works fine if you stretch it about 1000mm
bigger. But if you stretch it 2000mm it doesn't work...

Of course the example I am attaching I prefer that
it has the linear parameter outside the frames and not inside, so that when I
pick the arrow to lengthen the window, I will select the corner of the wall and
not 50mm apart from the wall.

Your move (Move Center Arc) and scale are probably conflicting with one another so that the half moon arc are performing oddly.
I know you are trying to get the parameter to the outside but short of that you can move the grip point to the outside so that it will stretch to the edge you want.
Good use of the 1/4 and 3/4 multiplier on the divider stretches. I've done that on a couple of other DB's I have. You do have to be careful about what thru entities you choose when stretching this way because you can easily double up on the geometry.

Thanks for the advices.

I will be waiting for you to find some time to
think of a solution on the parameter to get to the outside. Apart from the grip
I will be using the total width of the windows to make a table of the dimensions
of the windows and it will be confusing to see 900mm and to have to write
1000mm.

But for the time being I know I can move the grip
of the block (the insertion point of the block). But can I move the grip of the
parameter? Because I want to grip on that arrow to stretch it so that it reaches
the wall.

Thanks again

Any of the grips you can pick individually w/o choosing the parameter and move them where you want.

Okay so here is my contribution...

[Anonymous]

Yes, you are right about the grips. I can move them
separately. Thank you.

As far as the block is concerned I tried and tried
but I cannot find the mistake or conflict on the move and scale. Can anyone help
me on that please? Or maybe I should repost this so somebody else may help
me?

I am currently playing with Dynamic blocks and am having a problem with flip affecting stretches. I was looking for help and noticed that the block that Juris submitted has the same problem I have - when you flip the door the 90 degree stretches go the wrong way?

Any Ideas how to solve this?

[Charles_Shade]

Have you tried removing the Stretch Action from the flip selection set?
Regards, Charles Shade

[Ruari_c]

Thanks, for getting back. Yes, I have just tried that but it doesn't seem to make a difference, see the attached file which has both versions in it.

Add the Stretch2 Action to the selection set of both Flip Actions from single door 2.
Regards, Charles Shade

[Charles_Shade]

Have you tried working this from the center out both toward zero and 180? Instead of moving parts by this multiplier and that multiplier. I really think you are cancelling and/or doubling things out.
Yes you can repost in a new thread for potential other ideas. Items that have been tried here will be repeated since others will not have the benefit of reading what has been tried.

I can offer that version
