Using trim on rectangles or hash marks
Posted: Thu Dec 10, 2015 9:36 pm
Hello,
I am using Qcad recently to create shop drawings for masonry walls. I have a few questions regarding the tools and achieving a simple workflow. I hope you can assist in this matter!
Thus far I have been very impressed with Qcad. Having never delved into Cad software before, it is also slightly daunting. I have grasped a good amount of concepts, but am still lacking in a few areas. Namely the ability to delete un-needed lines, or understanding hash tool a bit better.
As a simple first question, is there a way to add to selections? Many other programs use the Cntrl button to add to selections. Click on a line, press and hold cntrl, click on next line and it adds to selection. It works in revers if using the Alt button. is there a similar function in Qcad? All I can do is simple select with one click, or area select. however if I have lines that fall within an area... I am at a loss as to how to select only certain lines. Please Advise. Below is my main question:
*********************************************************
In Example A (of the attachment) I have a simple rectangle. To my understanding the trim tool is what I am looking for, however it only works on arcs, circles, splines, or lines. So how would I delete portion 2? Aside from manually adjusting the lengths of the individual lines to the cutting lines intersection.
In example B the same question applies, but with the addition of a hatch infill. Is it possible to "cut" a hatch? or must one simply delete the hatch, adjust the perimeter, and then reapply the hatch?
The bottom of the picture shows what I am trying to achieve. By using the import tool I am essentially creating a floor plan showing CMU blocks to be laid in a wall.
In a separate file I created a single 8" CMU block to scale. Then I saved that file as its own .dxf file. In my plans I import the .dxf file/ block and either place it as many times as I want, or copy it along the line. The problem is a lot of times I need to "Cut" one of the blocks somewhere in between. I have been doing it manually, but am wondering if there is an easier way to do this other than: deleting the hatch pattern, moving the end points of the lines to the cut line, re-applying the hash pattern to the new shape.
***********************************
Now as an alternative that I have considered, but have no idea how to implement, I noticed there is a way to select the pattern for hatch area. There is even a pattern I use that I have noticed many architects use for masonry that works completely to scale for elevation views! Pattern AR-B816. Might there be a way to create a custom hatch pattern and use that (on a correctly measured rectangle) to achieve the desired effect I am trying to implement? If it is possible to create your own hatch patterns, where might those need to be saved and in what format? I look forward greatly to your reply. Thank you!
