How to create a dashed line with a space at the vertex

[Anonymous]

I'm trying to create or find a linetype that is exactly like the dashed linetype, but instead of the line starting and ending with a dash, it starts and ends with a space.

My first try was to inverse the dashed line:

*INVERSEDASHED,InverseDashed __ __ __ __ __ __ __ __ __ __ __ __ __ _
A,-.25,.5

which doesn't work, because you can't start a linetype with a negative. I've also tried fudging in the space using small values like 0.0001, and I've also tried a few different things using the MKLINETYPE command from the express tools.

I'm using Autocad 2014, and I am using polylines. I can't change PLINEGN to 1, because it would mess up all my other polylines.

Any ideas?

Plinegen only affects plines yet to be drawn.  The properties palette allows you to enable linetype generation on an object by object basis.

The linetype feature only has one alignment mode and requires pen down at start and end for lines.  Polylines will wrap as you know with linetype generation enabled.  You can use lengthen to move the lines away from the vertex and can insert markers at verticies that have wipeouts.

A Linetype have to start with a line segment, it can define as length 0 (point) but not with a space segment.

What you are asking for is somewhat common in mechanical drafting standards for situations where a hidden line represents hidden geometry that does not interact with visible geometry.  It's usually just a line that needs a gap at one end or the other.

The big difference for you is in wanting the 90 degree intersection of the hidden lines to not touch.

In either case I would advise that you observe the essential rule for hidden lines... It's hidden and for communication of a feature that should be dimensioned or otherwise represented as visible in another view, and NEVER gets a dimension applied to it.  Since we never dimension hidden lines/features, you should feel free to do as @dbroad suggests and drag the endpoints away from one another to represent the effect you wish.

Hidden geometry is only "eye candy" to assist and support another view.

Oh yeah... maybe it's not hidden geometry your after as I forgot you are using "Dashed".  In any case @dbroad ahd the right recommendation.

BTW... If you are not familiar and you have many intersections to reduce by a same amount you can use the Lengthen command with a negative Delta value.

Hello consistent gaps!
