Stretch Modifications input dimensions

[Mhooper]

Hi,

I worked for an architect in the past that had a modification of stretch that allowed you to set a dimension. For instance if you had a door way drawn in a stud wall set back from the wall 50mm and you wanted to change that to 100mm you could use the stretch command with another shortcut command to specify the distance from the wall.

 

The command list would be as follows:

 

-"s" (Stretch)

- Select objects to move, "Enter"

- Specify the basepoint to move (corner of door in this case).

-Then i would hit another command shortcut from there system. This would allow me to pick the point where i want the dimension to start from.

- Input the dimensions, in this case "100" , then enter to complete.

 

It seem simple the but very useful for more obscure applications.

 

I also understand in the application above you could just stretch 50mm across 50mm but this requires calculation. We want to get away from having to calculated all the time.

 

Any assistance would be greatly appreciated.

There is no calculation required to stretch an object an additional 50mm, 500mm or 5000mm. Pick your basepoint and at the line that reads Specify second point or : drag your mouse in the direction you want to go and type the distance. Done.

I dont think that i explained myself very well. See attached image.

 

Image 1: Is the orginal drawing

Image 2: is what i want to achieve.

 

In this example there is an opening in a blockwork wall. Image 1 can see the opening is set 519mm from the end of the wall. This doesnt make sense and should be 600mm. In image 1 you can use stretch move the opening from point 'A' to 'B' by adding 81mm. However this require calculation.

 

In the firm i use to work for they used stretch to shift the door opening like in image 2. First you would use the stretch command and select the opening. Select point 'a' which then you would hit there custom shortcut then click point 'c' and type the dimension (in this case '600') this would move the opening to point 'c'.

 

I hope that's clearer.

It had to be a custom lisp routine assigned to the Stretch command.

 

Personally I don't find the calculation as you call it to be that much of a challenge.

In this example it may seem simplistic but it can save a huge amount of time if you can reduce the number of key stroke required to get a result. Thanks for your input ReMark.

 

If anyone else has a solution to the problem please post!!!

There is a solution. Call someone over at your old company and ask them if they would mind giving you a copy of the lisp routine or tell you how it was written.
