Author Topic: Draw Multi-line without jig? (Read 4588 times)

josano · « **on:** October 15, 2010, 03:02:25 PM »

Hello Friends,

I was looking for information on how to draw lines without jig.
Unfortunately, I can not find information.
My idea is to draw an example profile metallic as the photo attached.
My idea is more or less what the post code http://www.theswamp.org/index.php?topic=34430.0, only without jig.
Has anyone thought of anything like that or know where can I start?
Something like clicking the start / end point and generate the lines
Thanks guys for the help.

Hugs,
Josano

Hi Fixo,

I see the Thread, greatly helped in ideas.
I created a code that adds only three lines that all lines are placed one above the other, could not change the starting point of lines 2 and 3.
Friends, how do I change? I put comments on lines of points.

How are you subtracting or what are you subtracting?

josano · « **Reply #4 on:** October 18, 2010, 04:38:40 PM »

I want to create three lines
a point which has been clicked a 44.7 below and 51 below the other first, always having as reference the first

--------------------------- (Line 1) - reference to the following two lines

--------------------------- (Line 2)
--------------------------- (Line 3)

Perhaps an Offset would suit you

Friends,

Can any of you help me with the code below?
I can insert a bracket of 51 mm x 6.3 mm horizontally.
If I try to enter angle values are not correct.
How can I leave the values prevail even with angle?

Friends,

I made some modifications to the code with the tips.
I can now insert with angle but for some reason the values are only correct when I insert horizontally.
Below the code changed, some of you know where I could be wrong?

It looks like you get the angle and do nothing with it. angRes

josano · « **Reply #9 on:** October 22, 2010, 03:58:37 PM »

Jeff,

How do I add the angled lines?
I'm trying but I can not understand how to change the angle with the remaining values.

Hugs,
Josano

Jeff H · « **Reply #10 on:** October 22, 2010, 04:18:52 PM »

Thanks for the hug,
GetAngle I think will vary depending on "AUNITS" setting. All you getting is back is a double

Would you rather just let them pick a point a 3rd point like drawing a regular line but with the other 2 lines generated?

josano · « **Reply #11 on:** October 22, 2010, 04:25:34 PM »

Jeff,

I thought about how to generate all but dont know not yet know how to work well.
Then the form that was able to generate the other two lines.
I thank you for your help.

I'm going crazy from trying to insert correctly.

Hugs,
Josano

When I get a minute I will post something that might help.

In the meantime you can look at the developer's guide under these headings for ideas

Calculate Points and Values
Offset Objects
Transform Objects
Move Objects

You might also consider using polylines
Here is offsetting some lines but there probably is a better way.

Jeff, Bryco and friends,

Thank you all for your support.
I think now I can develop the part of beam.
Please excuse me for the work, but I'm still crawling in autocad.net, with everyone's help understand more about lines, polylines and offset.

Hugs,
Josano
